Method Detail

canSucceed

public static final Boolean canSucceed(Stage upstream,
                                       Stage downstream)

Tests whether the specified downstream stage can succeed the specified upstream stage.

Parameters:

upstream - the upstream stage

downstream - the stage consuming data produced by the upstream stage

Returns:

true or false on definitive identification of compatibility or null if unable to determine compatibility due to missing metadata.

canSucceedOnBranch

public static final Boolean canSucceedOnBranch(Stage upstream,
                                               String downstreamBranchKey,
                                               Stage downstream)

Tests whether the specified downstream stage can succeed the specified upstream stage on a branch pipeline identified by the given branch key.

Parameters:

upstream - the upstream stage

downstreamBranchKey - the key identifying the branch receiving data from the upstream stage

downstream - the stage consuming data produced by the upstream stage

Returns:

true or false on definitive identification of compatibility or null if unable to determine compatibility due to missing metadata.
