Detailed Description

A regexp matching class.

A regular expression matching class.

Constructor & Destructor Documentation

Regexp() [1/3]

Regexp

(

)

Creates a new, empty regexp.

Referenced by operator=(), and Regexp().

Regexp() [2/3]

Regexp ( const char * value, bool extended = false, bool insensitive = false )

explicit

Creates a new initialized regexp.

Parameters

value	Initial value of the regexp.
extended	True to use POSIX Extended Regular Expression syntax
insensitive	True to not differentiate case

Regexp() [3/3]

Regexp

(

const Regexp &

value

)

Copy constructor.

Parameters

value

Initial value of the regexp.

References Regexp().

~Regexp()

virtual ~Regexp ( )

virtual

Destroys the regexp, disposes the memory.

Member Function Documentation

changed()

virtual void changed ( )

protectedvirtual

Called whenever the value changed (except in constructors) to recompile.

Reimplemented from String.

compile()

bool compile ( ) const

inline

Makes sure the regular expression is compiled

Returns

True if successfully compiled, false on error

References doCompile().

doCompile()

bool doCompile ( ) const

protected

Compile the regular expression

Returns

True if successfully compiled, false on error

References matches().

Referenced by compile().

isCaseInsensitive()

bool isCaseInsensitive

(

)

const

Return the Case Insensitive flag

Returns

True if not differentiating case

isExtended()

bool isExtended

(

)

const

Return the POSIX Extended syntax flag

Returns

True if using POSIX Extended Regular Expression syntax

matches() [1/2]

bool matches

(

const char *

value

)

const

Checks if the pattern matches a given value

Parameters

value

String to check for match

Returns

True if matches, false otherwise

Referenced by doCompile(), and matches().

matches() [2/2]

virtual bool matches ( const String & value ) const

inlinevirtual

Checks if the pattern matches a string

Parameters

value

String to check for match

Returns

True if matches, false otherwise

Reimplemented from String.

References matches(), and String::safe().

operator=()

Regexp & operator= ( const char * value )

inline

Assignment from char* operator.

References String::operator=(), and Regexp().

setFlags()

void setFlags	(	bool	extended,
		bool	insensitive )

Change the expression matching flags

Parameters

extended	True to use POSIX Extended Regular Expression syntax
insensitive	True to not differentiate case
