Method Detail

next

public BinaryRow next(BinaryRow reuse)
               throws IOException

Description copied from interface: MutableObjectIterator

Gets the next element from the collection. The contents of that next element is put into the given reuse object, if the type is mutable.

Specified by:

next in interface MutableObjectIterator<BinaryRow>

Parameters:

reuse - The target object into which to place next element if E is mutable.

Returns:

The filled object or null if the iterator is exhausted.

Throws:

IOException - Thrown, if a problem occurred in the underlying I/O layer or in the serialization / deserialization logic

next

public BinaryRow next()
               throws IOException

Description copied from interface: MutableObjectIterator

Gets the next element from the collection. The iterator implementation must obtain a new instance.

Specified by:

next in interface MutableObjectIterator<BinaryRow>

Returns:

The object or null if the iterator is exhausted.

Throws:

IOException - Thrown, if a problem occurred in the underlying I/O layer or in the serialization / deserialization logic
