Method Detail

getSplitterNumWork

public int getSplitterNumWork()

Returns the number of work functions for this Splitter.

Specified by:

getSplitterNumWork in interface SplitterIter

Overrides:

getSplitterNumWork in class SIRSplitJoinIter

Returns:

number of work functions for this Splitter

getSplitPushWeights

public int[] getSplitPushWeights(int nWork)

Returns distribution of weights on a particular invocation of work function for Splitter of this Stream. The distribution is simply an array of ints, with numChildren elements. The value at index 0 corresponds to number of items pushed out to 1st child, etc.

Specified by:

getSplitPushWeights in interface SplitterIter

Overrides:

getSplitPushWeights in class SIRSplitJoinIter

Returns:

distribution of weights on a particular invocation of work function for the Splitter of this Stream.

getSplitPop

public int getSplitPop(int nWork)

Returns number of data items consumed by a particular invocation of work function for Splitter of this Stream. These are the items that will end up being pushed out to the children of this Stream.

Specified by:

getSplitPop in interface SplitterIter

Overrides:

getSplitPop in class SIRSplitJoinIter

Returns:

number of data items consumed by a particular invocation of work function for Splitter of this Stream.

getJoinerNumWork

public int getJoinerNumWork()

Returns the number of work functions for the Joiner of this Stream.

Specified by:

getJoinerNumWork in interface JoinerIter

Overrides:

getJoinerNumWork in class SIRSplitJoinIter

Returns:

number of work functions for the JOiner of this Stream

getJoinPopWeights

public int[] getJoinPopWeights(int nWork)

Returns distribution of weights on a particular invocation of work function for Joiner of this SplitJoin. The distribution is simply an array of ints, with numChildren elements. The value at index 0 corresponds to number of items popped from 1st child, etc.

Specified by:

getJoinPopWeights in interface JoinerIter

Overrides:

getJoinPopWeights in class SIRSplitJoinIter

Returns:

distribution of weights on a particular invocation of work function for Joiner of this SplitJoin.

getJoinPush

public int getJoinPush(int nWork)

Returns number of data items produced by a particular invocation of work function for Joiner of this SplitJoin. These are the items that were consumed from various children of this SplitJoin.

Specified by:

getJoinPush in interface JoinerIter

Overrides:

getJoinPush in class SIRSplitJoinIter

Returns:

number of data items produced by a particular invocation of work function for Joiner of this SplitJoin.
