com.ibm.icu.util.BytesTrie.Iterator

All Implemented Interfaces:

Iterator<BytesTrie.Entry>

Enclosing class:

BytesTrie

public static final class BytesTrie.Iterator
extends Object
implements Iterator<BytesTrie.Entry>

Iterator for all of the (byte sequence, value) pairs in a BytesTrie.

Method Summary

Modifier and Type	Method and Description
boolean	hasNext() Returns true if the iteration has more elements.
BytesTrie.Entry	next() Finds the next (byte sequence, value) pair if there is one.
void	remove() Iterator.remove() is not supported.
BytesTrie.Iterator	reset() Resets this iterator to its initial state.

Method Detail

reset

public BytesTrie.Iterator reset()

Resets this iterator to its initial state.

Returns:

this

hasNext

public 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<BytesTrie.Entry>

Returns:

true if there are more elements.

next

public BytesTrie.Entry next()

Finds the next (byte sequence, value) pair if there is one. If the byte sequence is truncated to the maximum length and does not have a real value, then the value is set to -1. In this case, this "not a real value" is indistinguishable from a real value of -1.

Specified by:

next in interface Iterator<BytesTrie.Entry>

Returns:

An Entry with the string and value of the next element.

Throws:

NoSuchElementException - - iteration has no more elements.

remove

public void remove()

Iterator.remove() is not supported.

Specified by:

remove in interface Iterator<BytesTrie.Entry>

Throws:

UnsupportedOperationException - (always)
