Method Detail

sendBuffer1

public int sendBuffer1(org.apache.flink.python.api.streaming.data.SingleElementPushBackIterator<IN1> input)
                throws IOException

Extracts records from an iterator and writes them to the memory-mapped file. This method assumes that all values in the iterator are of the same type. This method does NOT take care of synchronization. The caller must guarantee that the file may be written to before calling this method.

Parameters:

input - iterator containing records

Returns:

size of the written buffer

Throws:

IOException

sendBuffer2

public int sendBuffer2(org.apache.flink.python.api.streaming.data.SingleElementPushBackIterator<IN2> input)
                throws IOException

Extracts records from an iterator and writes them to the memory-mapped file. This method assumes that all values in the iterator are of the same type. This method does NOT take care of synchronization. The caller must guarantee that the file may be written to before calling this method.

Parameters:

input - iterator containing records

Returns:

size of the written buffer

Throws:

IOException
