Detailed Description

This class is a variation of a string that ignores case. Thus in all standard comparison (#==#, #<# etc) and search (Find()# etc) functions the case of the characters and strings is ignored.

The characters in the string still maintain their case. Only the comparison operations are affected. So printing etc will still display the string as entered.

Constructor & Destructor Documentation

PINLINE PCaselessString::PCaselessString

(

)

Create a new, empty, caseless string.

PINLINE PCaselessString::PCaselessString

(

const char *

cstr

)

Create a new caseless string, initialising it to the characters in the C string provided.

Parameters:

cstr	C string to initialise the caseless string from.

PINLINE PCaselessString::PCaselessString

(

const PString &

str

)

Create a caseless string, with a reference to the characters in the normal PString# provided. A PCaselessString may also be provided to this constructor.

Parameters:

str	String to initialise the caseless string from.

PCaselessString::PCaselessString

(

const std::string &

str

)

[inline]

Create a caseless string from a std::string

Parameters:

str	String to initialise the caseless string from.

PINLINE PCaselessString::PCaselessString	(	int	dummy,
		const PCaselessString *	str
	)			[protected]

Member Function Documentation

PINLINE PCaselessString & PCaselessString::operator=

(

const PString &

str

)

Assign the string to the current object. The current instance then becomes another reference to the same string in the str# parameter.

Returns:

reference to the current PString object.

Parameters:

str	New string to assign.

Reimplemented from PString.

PINLINE PCaselessString & PCaselessString::operator=

(

const char *

cstr

)

Assign the C string to the current object. The current instance then becomes a unique reference to a copy of the cstr# parameter. The cstr# parameter is typically a literal string, eg: {verbatim} myStr = "fred"; {verbatim}

Returns:

reference to the current PString object.

Parameters:

cstr	C string to assign.

Reimplemented from PString.

PINLINE PCaselessString & PCaselessString::operator=

(

char

ch

)

Assign the character to the current object. The current instance then becomes a unique reference to a copy of the character parameter. eg: {verbatim} myStr = 'A'; {verbatim}

Returns:

reference to the current PString object.

Parameters:

ch	Character to assign.

Reimplemented from PString.

virtual PObject* PCaselessString::Clone

(

)

const [virtual]

Make a complete duplicate of the string. Note that the data in the array of characters is duplicated as well and the new object is a unique reference to that data.

Reimplemented from PString.

virtual Comparison PCaselessString::InternalCompare	(	PINDEX	offset,
		char	c
	)			const [protected, virtual]

Reimplemented from PString.

virtual Comparison PCaselessString::InternalCompare	(	PINDEX	offset,
		PINDEX	length,
		const char *	cstr
	)			const [protected, virtual]

Reimplemented from PString.
