Detailed Description

Represents mapping of numeric values of tagnames to their string value.

Represents mapping of numeric values of tagnames to their string value, which takes therefore a string, e.g. <tagname></tagname> or <tagname/>, as arguments and returns the string value for a (numeric value of a) tagname.

Note:: Tagnames are internally represented by numbers!
SINGLETON PATTERN!

const char * TagMap::getTag ( unsigned id ) [inline]

Returns string value for the entered (numeric value of a) tagname.

unsigned TagMap::insertTag ( const char * tag )

Inserts a new string of a tagname and returns the numeric value.

Parameters:

[in] tag Pointer to a char object (string of a tagname).

Return values:

unsigned

Numeric value for string value of a tagname.

unsigned TagMap::insertTagWithOffset	(	const char *	tag,
		unsigned	start_offset,
		unsigned	end_offset
	)

Inserts a new string of a tagname and returns the numeric value.

Inserts a new string of a tagname and returns the numeric value. Thereby the string is copied starting from position start up to position end.

Parameters:

`[in]`	tag	Pointer to a char object (string of a tagname).
`[in]`	start_offset	The start offset (from the left).
`[in]`	end_offset	The end offset (from the right).

Return values:

unsigned

Numeric value for string value of a tagname.
