Method Detail

getSize

public long getSize()

Description copied from interface: AmetysObjectIterator

Returns the number of elements in the iterator. If this information is unavailable, returns -1.

Specified by:

getSize in interface AmetysObjectIterator<A extends AmetysObject>

Returns:

a long

getPosition

public long getPosition()

Description copied from interface: AmetysObjectIterator

Returns the current position within the iterator. The number returned is the 0-based index of the next element in the iterator, i.e. the one that will be returned on the subsequent next call.
Note that this method does not check if there is a next element, i.e. an empty iterator will always return 0.

Specified by:

getPosition in interface AmetysObjectIterator<A extends AmetysObject>

Returns:

a long

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<A extends AmetysObject>

next

public A next()

Specified by:

next in interface Iterator<A extends AmetysObject>

_fetchNextObject

private boolean _fetchNextObject()

Set nextObject to the next object.

Returns:

If there are no more objects then return false. Otherwise, return true.

_internalHasNext

private boolean _internalHasNext()

_internalNext

private A _internalNext()
