Method Detail

getStageCount

int getStageCount()

Get a count of all stages.

Returns:

the total count of all stages.

getStageChildren

int[] getStageChildren(int stage)

Find children of a given pipeline stage. Pass -1 to find the children of the root stage.

Parameters:

stage - is the stage index to get the children of.

Returns:

the pipeline stages that represent those children.

getStageParent

int getStageParent(int stage)

Find parent of a given pipeline stage. Returns -1 if there's no parent (it's the root).

Parameters:

stage - is the stage index to get the parent of.

Returns:

the pipeline stage that is the parent, or -1.

getStageConnectionName

java.lang.String getStageConnectionName(int stage)

Get the connection name for a pipeline stage.

Parameters:

stage - is the stage to get the connection name for.

Returns:

the connection name for that stage.

checkStageOutputConnection

boolean checkStageOutputConnection(int stage)

Check if a stage is an output stage.

Parameters:

stage - is the stage to check.

Returns:

true if the stage represents an output connection.

getOutputCount

int getOutputCount()

Return the number of output connections.

Returns:

the total number of output connections in this specification.

getOutputStage

int getOutputStage(int index)

Given an output index, return the stage number for that output.

Parameters:

index - is the output connection index.

Returns:

the stage number.
