Method Summary

Modifier and Type	Method and Description
void	finish() Make sure that the iterator is complete, and recover resources.
boolean	hasNext() true if another Feature object is available
NestedPointFeatureCollection	next() Returns the next NestedPointFeatureCollection object You must call hasNext() before calling next(), even if you know it will return true.
void	setBufferSize(int bytes) Hint to use this much memory in buffering the iteration.

Method Detail

hasNext

boolean hasNext()
         throws java.io.IOException

true if another Feature object is available

Returns:

true if another Feature object is available

Throws:

java.io.IOException - on i/o error

next

NestedPointFeatureCollection next()
                           throws java.io.IOException

Returns the next NestedPointFeatureCollection object You must call hasNext() before calling next(), even if you know it will return true.

Returns:

the next NestedPointFeatureCollection object

Throws:

java.io.IOException - on i/o error

setBufferSize

void setBufferSize(int bytes)

Hint to use this much memory in buffering the iteration. No guarentee that it will be used by the implementation.

Parameters:

bytes - amount of memory in bytes

finish

void finish()

Make sure that the iterator is complete, and recover resources. You must complete the iteration (until hasNext() returns false) or call finish(). may be called more than once.
