Detailed Description

A table which stores sequences of unicode characters, referenced by hash keys.

The hash key itself is the same size as a unicode character ( ushort ) so that it can occupy the same space in a structure.

Member Function Documentation

ushort ExtendedCharTable::createExtendedChar	(	ushort *	unicodePoints,
		ushort	length
	)

Adds a sequences of unicode characters to the table and returns a hash code which can be used later to look up the sequence using lookupExtendedChar()

If the same sequence already exists in the table, the hash of the existing sequence will be returned.

Parameters

unicodePoints	An array of unicode character points
length	Length of unicodePoints

ushort * ExtendedCharTable::lookupExtendedChar	(	ushort	hash,

Looks up and returns a pointer to a sequence of unicode characters which was added to the table using createExtendedChar().

Parameters

hash	The hash key returned by createExtendedChar()
length	This variable is set to the length of the character sequence.

Returns

A unicode character sequence of size length.
