Method Detail

getVertexIdMessageBytesIterator

VertexIdMessageBytesIterator<I,M> getVertexIdMessageBytesIterator()

Get specialized iterator that will instantiate the vertex id and message of this object. It will only produce message bytes, not actual messages and expects a different encoding.

Returns:

Special iterator that reuses vertex ids (unless released) and copies message bytes

getVertexIdMessageIterator

VertexIdMessageIterator<I,M> getVertexIdMessageIterator()

Get specialized iterator that will instiantiate the vertex id and message of this object.

Returns:

Special iterator that reuses vertex ids and messages unless specified
