CharMap

public CharMap(String source,
               String destination)

Creates a char map with the given source and destination characters. If the strings do not have the same length, subsequent characters in the longer string are ignored. The first mapping is defined as source[0] --> destination[0], all other mappings in an analogous way with matching character indices in the two strings.

Parameters:

source - source characters

destination - destination characters

Throws:

IllegalArgumentException - if any of the destination characters is the zero character

Method Detail

Parameters:

source - source characters
