Method Detail

isJobDescriptor

public boolean isJobDescriptor()

Returns:

true if this node represents a inlined job definition or simple job reference, otherwise false

getSeriesLength

public int getSeriesLength()

For nodes representing a flow or split, return how many are in the series of things to run (so the number to run in sequence or the number to run in parallel).

Returns:

the length of the series for flow or split nodes, otherwise -1

getSeriesElement

public JobNode getSeriesElement(int index)

For nodes representing a flow or a split, return a specific element in the series of things that will run either sequentially or in parallel.

Parameters:

index - the element of interest

Returns:

the indicated series or null if this is not a flow/split node

getSeries

public java.util.List<JobNode> getSeries()

For nodes representing a flow or a split, return the series of elements to run in sequence/parallel.

Returns:

the series of elements for this flow/split, or null if not a flow/split node
