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

◆ createExtendedChar()

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.
