Collaboration diagram for TWildcardMatcher< TChar >:

Class Description

template<typename TChar>
class aworx::lib::strings::util::TWildcardMatcher< TChar >

---

This utility class implements so called wildcard string matching. Wildcard characters are

• '*': Matches zero or more characters.
• '?': Matches exactly one character.

Method Compile accepts the pattern string and translates it to an internal (simple) list of "matching commands". This way, the class is optimized for performance, because after compilation, subsequent invocations of Match do not need to parse the pattern string.

Template Parameters

TChar

The character type. Implementations for nchar and wchar are provided with type definitions aworx::WildcardMatcherN and aworx::WildcardMatcherW.

Constructor & Destructor Documentation

TWildcardMatcher()

TWildcardMatcher ( const TString< TChar > &  pattern = NullString() )

inline

---

Constructs a WildcardMatcher to work on a given string. Passes the optional parameters to method Compile.

Parameters

pattern

The string pattern to match. Defaults to NullString() to allow parameterless construction, with later invocation of Compile.

Compile()

template ALIB_API void Compile

(

const TString< TChar > &

pattern

)

Resets this object to use the given pattern.

Parameters

pattern

The string pattern to match.

Here is the call graph for this function:

Match()

template ALIB_API bool Match	(	const TString< TChar > &	haystack,
		Case	sensitivity = Case::Sensitive
	)

---

Tests if given haystack matches the actual pattern. If Compile was not invoked or an empty pattern string was given, true is returned.

Parameters

haystack	The string to test.
sensitivity	Denotes whether the matching is performed case sensitive. Defaults to Case::Sensitive.

Returns

true if given haystack matches the actual pattern, false otherwise.
