Method Detail

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

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

skip

public void skip(long skipNum)

Description copied from interface: AmetysObjectIterator

Skip a number of elements in the iterator.
The default implementation simply calls skipNum times Iterator.next().

Specified by:

skip in interface AmetysObjectIterator<A extends AmetysObject>

Parameters:

skipNum - the non-negative number of elements to skip

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>

remove

public void remove()

Specified by:

remove in interface Iterator<A extends AmetysObject>
