Class Trie2.CharSequenceIterator

java.lang.Object

com.ibm.icu.impl.Trie2.CharSequenceIterator

All Implemented Interfaces:

Iterator<Trie2.CharSequenceValues>

Enclosing class:

Trie2

public class Trie2.CharSequenceIterator
extends Object
implements Iterator<Trie2.CharSequenceValues>

An iterator that operates over an input CharSequence, and for each Unicode code point in the input returns the associated value from the Trie2. The iterator can move forwards or backwards, and can be reset to an arbitrary index. Note that Trie2_16 and Trie2_32 subclass Trie2.CharSequenceIterator. This is done only for performance reasons. It does require that any changes made here be propagated into the corresponding code in the subclasses.
