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.

Method Summary

Modifier and Type	Method and Description
boolean	hasNext() Returns true if the iteration has more elements.
boolean	hasPrevious()
Trie2.CharSequenceValues	next() Returns the next element in the iteration.
Trie2.CharSequenceValues	previous()
void	remove() Iterator.remove() is not supported by Trie2.CharSequenceIterator.
void	set(int i)

Method Detail

set

public void set(int i)

hasNext

public final boolean hasNext()

Description copied from interface: Iterator

Returns true if the iteration has more elements. (In other words, returns true if Iterator.next() would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator<Trie2.CharSequenceValues>

Returns:

true if the iteration has more elements

hasPrevious

public final boolean hasPrevious()

next

public Trie2.CharSequenceValues next()

Description copied from interface: Iterator

Returns the next element in the iteration.

Specified by:

next in interface Iterator<Trie2.CharSequenceValues>

Returns:

the next element in the iteration

previous

public Trie2.CharSequenceValues previous()

remove

public void remove()

Iterator.remove() is not supported by Trie2.CharSequenceIterator.

Specified by:

remove in interface Iterator<Trie2.CharSequenceValues>

Throws:

UnsupportedOperationException - Always thrown because this operation is not supported
