Parameters:

source - Enumeration instance to get elements from.

Method Detail

internalHasNext

protected boolean internalHasNext()

Description copied from class: AbstractEnumerator

Returns whether the enumerator has more elements.

This method is the internal counterpart of AbstractEnumerator.hasNext().

Specified by:

internalHasNext in class AbstractEnumerator<E>

Returns:

true if the enumerator has more elements, false otherwise.

internalNext

protected E internalNext()

Description copied from class: AbstractEnumerator

Returns the next enumerated element.

This method is the internal counterpart of AbstractEnumerator.hasNext()

Specified by:

internalNext in class AbstractEnumerator<E>

Returns:

next enumerated element.

cleanup

protected void cleanup()

Description copied from class: AbstractEnumerator

Cleans up the internals of the current enumerator when enumeration ends.
