This is the path for logging to the internal domain. By manipulating this Log Domain's Verbosity, the verbosity of ALox itself can be controlled. For example, with Verbosity.INFO, the 'on the fly' creation of Log Domains are logged, which can be helpful to determine the Lo bg Domains that are created by libraries and larger projects.
The following Subdomains are used by ALox:
Subdomain | Description |
---|---|
LGR | Used when Loggers are registered, retrieved or removed from a Lox and when the Verbosity of a Log Domain for a Logger is changed. In addition used with method Lox::SetStartTime. |
DMN | Used when Log Domains are registered (on first use), when Scope Domains are set or removed and when Domain Substitution Rules are set. |
PFX | Used when Prefix Logables are set or removed. |
THR | Used with method Lox::MapThreadName. |
LGD | Used with storing and retrieving Log Data objects. |
In addition, class ALoxReportWriter logs into subdomain 'REPORT'
.
Constructs a new, empty Lox with the given name. The name is immutable and all Lox objects registered with ALox must be unique. Lower case letters in the name are converted to upper case. The name "Log"
is reserved for the internal default singleton used for debug-logging. In addition, name "GLOBAL"
is not allowed.
If parameter register is true
(the default), static method alib::lox,ALoxCamp::Register "lox,ALoxCamp::Register" is invoked and the object will be retrievable with static method alib::lox,ALoxCamp::Get "lox,ALoxCamp::Get". In some situations, such 'registration' may not be wanted.
name | The name of the Lox. Will be copied and converted to upper case. |
doRegister | If true , this object is registered with static class alib::lox,ALoxCamp "lox,ALoxCamp". Optional and defaults to true . |

. If executed, Verbosity::Error is used.
The first object provided may be a domain name. All values are passed to EntryDetectDomain. See documentation of this method for information on how to avoid ambiguities in respect to domain names.
If one of the arguments (or a single argument given) is of type alib::boxing,TBoxes "boxing,TBoxes", then the contents of this list are inserted into the list of logables. This allows collecting logables before invoking the method.

Logs the current list of Logables that previously have been received using GetLogableContainer with the given verbosity.
This method is usually not used directly. Instead, methods Info, Verbose, Warning and Error provide simpler interfaces which take variadic arguments that are collected in a list of boxed objects and then passed to this methods.
Note that the other interface methods accept an "external" list of boxes as a parameter. as well. This means also with these methods it is allowed to collect the logables in an user-specific list first and later pass them to these methods.
Hence, the use of this method is recommended only if the verbosity of a log statement is evaluated only at run-time.

Logs a list of Logables with the given Verbosity.
If more than one Logable is given and the first one is of string-type and comprises a valid domain path, then this first argument is interpreted as the domain name! Valid domain path are strings that consists only of characters of the following set:
'-'
),'_'
) and'/'
).If a first Logable could be misinterpreted as being a domain name, an empty string (the "neutral" domain) has to be added as a first argument. Alternatively, a character which is illegal in respect to domain names could be added to the first argument, for example a simple space at the end of an output string.

Returns a reference to a list of boxes to be used for logging. The list is recycled from a previous log operation and cleared. The method may be used to retrieve a container for logables that then are collected until finally logged.
Note that the Lox instance has to be acquired before invoking this method and the container returned must be used only while the object is still acquired.
With each recursive acquirement of this object, a different container is returned. This is implemented to allow recursive log calls.

Logs given logables once, up to quantity times, or every n-th time. In its simplest overloaded version, the counter is bound to the source code line, hence, only the first execution of this exact Log Statement is executed.
With parameter group, a set of Log Statements that share the same group key, can be grouped and of such set, only the one which is first executed actually logs.
Alternatively, when key is omitted (or nullptr or empty), but a Scope is given with parameter scope, then the counter is associated with the scope.
Finally, parameters key and scope can also be used in combination. The key is then unique in respect to the Scope provided.
Using, none, one or both of the parameters group and scope, among others, the following use cases can be achieved.
When parameter quantity is a negative value, the log statement is executed every n-th time instead n-times. E.g, if quantity is -5
, the first statement is executed and afterwards every fifth invocation.

The given scopeDomain becomes the default domain path for given scope. This means, that any subsequent log invocations (from within this same scope) can omit the domain parameter, or if they provide one, this Scope Domain path is prepended. If subsequent log calls specify a domain name with a leading '/' character, then the Scope Domain of the scope is ignored.
Furthermore, if the given scope is an inner scope, outer scopes are prepended to the given scopeDomain when the resulting domain of a log invocation is evaluated. Again, this behavior can be overruled by prepending a leading '/' character to scopeDomain.
To remove a previously set Scope Domain a nulled or empty string has to be passed with parameter scopeDomain. For Scope::ThreadOuter and Scope::ThreadInner, passing an empty or nulled string removes the most recently added domain path. For removing an explicitly named domain path of Scope::ThreadOuter and Scope::ThreadInner use method RemoveThreadDomain.

Adds a Domain Substitution Rule. Domain Substitution is performed as a last step when evaluating the domain path of a Log Statement, taking Scope Domains and the optional parameter domain of the statement into account.
Wildcards
Parameter domainPath supports 'wildcard' character '*'
at its beginning and at its end (or both). This allows having four types of rules:
*
at the end of domainPath)*
at the start of domainPath)*
at both, start and the end of domainPath)Only minimal checks are performed, e.g., if an exact match is requested, but domainPath does not start with character '/'
. In this and some other cases, the rule is not stored and an internal warning is logged. Further checks, for example, for illegal domain path characters, are not performed. (Illegal domain path characters will be eliminated when the resulting domain path is to be created internally).
Circular Dependencies
If the given rules have circular dependencies, only a limited number (ten) replacements are performed. If this number of replacements for one Log Statement is exceeded, an internal warning message is logged. This is done only once over the life-time of a Logger.
Application of Rules
Rules are applied in the order of their definition. After all rules have been applied, this is repeated as long as at least one rule matches (up to ten times).
Deletion of Rules To delete a rule, invoke the method with the same parameter domainPath but with a 'nulled' or empty string for parameter replacement. To delete all rules, invoke the method with parameter domainPath 'nulled' or empty.
Final remarks Domain substitution is useful to permanently change ('redirect') domain paths of 3rd party code (e.g., libraries using ALox) or log statements that must not be changed for other reasons. It is advised to not 'overuse' this feature, as side effects are inherent to the concept of Domain Substitution. For example, an unwanted side effect might be that Prefix Logables are not applicable to the substituted domain, while other Prefix Logables are bound to the resulting domain.
For Lox objects that should be protected of external manipulation, it is advisable to remove all Domain Substitution Rules right after the Lox was created by invoking this method with a nulled value for parameter domainPath. The reason is that otherwise, through configuration files or command line parameters, domains of the Lox can be substituted and then the resulting domains Verbosities be overwritten using further configuration variables. Any prioritized 'internal' setting of Verbosities this way could be circumvented!
For more information consult the chapter 15 Log Domain Substitution of the Programmer's Manual.

The given prefix becomes a Prefix Logable associated to the given Log Domain. Prefix Logables associated with the Log Domain are added to the list of Logables right before the main Logable of the Log Statement itself. Multiple Prefix Logables can be added per Log Domain.

The given prefix becomes a Prefix Logable provided to loggers with each log statement executed within the given scope. The list of objects received by a logger is sorted from outer scope to inner scope. The logable of the Log Statement itself, is the last in the list, except one or more Prefix Logables of Scope::ThreadInner are set. Those are (similar to how this Scope is used with Scope Domains) appended to the end of the list.
To remove a previously set Prefix Logable, nullptr
has to be passed with parameter prefix. For Scope::ThreadOuter and Scope::ThreadInner, passing nullptr
(respectively with the overloaded method accepting string messages, a nulled string) removes the most recently added Prefix Logable.

Adds path to an internal list of substrings that are used to trim the path of a source file name. Trimmed paths are used for Scope mechanisms and can be logged (e.g., with meta-information of class TextLogger.
By default such setting affects all instances of class Lox, not only this instance. This can be altered using parameter global. one other The given trim information can either

Parameter trimReplacement optionally provides a replacement string for the trimmed path. This can be used for example to provide the right absolute path for an IDE to find source files of a library.
Parameter includeString determines if the searched substring should be included in the resulting source path or not. In addition, parameter trimOffset, which can be negative or positive, is added to the position of trimming. This can be used to increase the length of the search path, and then cut only a portion of what was searched for.

Sets the Verbosity of the Log Domain which is evaluated from parameter domain and applicable Scope Domains. The verbosity given is set recursively for all Subdomains.
With the first invocation of this method for a distinct logger, this Logger is registered with this Lox. In this case, before setting the given Verbosity for the evaluated subdomain, the Verbosity for all domains is set to Verbosity::Off.
To deregister a Logger with a Lox, use method RemoveLogger. To 'disable' a Logger, invoke this method with parameters verbosity equaling to Verbosity::Off and domain to "/"
.
Optional parameter priority defaults to Standard, which is a lower priority than those of the standard plug-ins of external configuration data. Therefore, external configuration by default 'overwrite' settings made from 'within the source code', which simply means by invoking this method.
The parameter can be provided for two main reasons:
Config::PriorityOf(Priority::Standard) + 1
, then this subdomain will not be affected by future invocations of this method with standard-priority given.For more information on how to use external configuration variables with priority and on protecting verbosity settings, consult the ALib Module ALox - Programmer's Manual.
