Member Enumeration Documentation

NFHint

enum NFHint

strong

This is a list of flags that store information obbout the format of the literal given in the expression string. This information is used with the generation of a normalized version of the literal.

Enumerator
NONE	No hint.
Scientific	Float was given in scientific format.
Hexadecimal	Integral value was given in hexadecimal format.
Octal	Integral value was given in octal format.
Binary	Integral value was given in binary format.

Constructor & Destructor Documentation

ASTLiteral() [1/3]

ASTLiteral ( const String &  string, integer  position  )

inline

Parameters

string	The value of the literal.
position	The index of this AST in the expression string.

Definition at line 113 of file ast.hpp.

ASTLiteral() [2/3]

ASTLiteral ( integer  value, integer  position, NFHint  hint = NFHint::NONE  )

inline

Constructs an integer literal.

Parameters

value	The value of the literal.
position	The index of this AST in the expression string.
hint	A hint about the format that expression string used to express the literal.

Definition at line 126 of file ast.hpp.

ASTLiteral() [3/3]

ASTLiteral ( double  value, integer  position, NFHint  hint = NFHint::NONE  )

inline

Constructs a floating point literal.

Parameters

value	The value of the literal.
position	The index of this AST in the expression string.
hint	Optional information about the number format that was detected while parsing.
