Constructor Detail

ElementAddressableVectorIterator

public ElementAddressableVectorIterator(T vector)

Constructs an iterator for the ElementAddressableVector.

Parameters:

vector - the vector to iterate.

ElementAddressableVectorIterator

public ElementAddressableVectorIterator(T vector,
                                        ArrowBufHasher hasher)

Constructs an iterator for the ElementAddressableVector.

Parameters:

vector - the vector to iterate.

hasher - the hasher to calculate the hash code.

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<ArrowBufPointer>

next

public ArrowBufPointer next()

Retrieves the next pointer from the vector.

Specified by:

next in interface Iterator<ArrowBufPointer>

Returns:

the pointer pointing to the next element in the vector. Note that the returned pointer is only valid before the next call to this method.

next

public void next(ArrowBufPointer outPointer)

Retrieves the next pointer from the vector.

Parameters:

outPointer - the pointer to populate.
