Method Detail

reset

public CharsTrie.Iterator reset()

Resets this iterator to its initial state.

Returns:

this

hasNext

public boolean hasNext()

Description copied from interface: Iterator

Returns true if there is at least one more element, false otherwise.

Specified by:

hasNext in interface Iterator<CharsTrie.Entry>

Returns:

true if there are more elements.

Iterator.next()

next

public CharsTrie.Entry next()

Finds the next (string, value) pair if there is one. If the string 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<CharsTrie.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<CharsTrie.Entry>

Throws:

UnsupportedOperationException - (always)
