Constructor Details

Iterator

private Iterator(byte[] trieBytes,
 int offset,
 int remainingMatchLength,
 int maxStringLength)

Method Details

reset

public BytesTrie.Iterator reset()

Resets this iterator to its initial state.

Returns:

this

hasNext

public boolean hasNext()

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)

truncateAndStop

private BytesTrie.Entry truncateAndStop()

branchNext

private int branchNext(int pos,
 int length)
