will be removed in OMERO 5.2, so use the new graphs implementation

@Deprecated

Method Summary

Methods

Modifier and Type	Method and Description
GraphStep	create(int idx, List<GraphStep> stack, GraphSpec spec, GraphEntry entry, long[] ids) Deprecated.
GraphSteps	postProcess(List<GraphStep> steps) Deprecated. Gives the GraphStepFactory a chance to add pre or post-steps for validation and similar activities.

Method Detail

create

GraphStep create(int idx,
               List<GraphStep> stack,
               GraphSpec spec,
               GraphEntry entry,
               long[] ids)
                 throws GraphException

Deprecated.

Parameters:

idx - Index which is being assigned to this step.

stack - Non-null stack of other steps which precede this one in the graph.

spec - Non-null GraphSpec which was used to define this step.

entry - Non-null GraphEntry which was used to define this step.

ids - Non-null, non-empty array of ids which were found for this GraphStep

Returns:

some specific GraphStep implementation which will permit arbitrary operations on all the nodes of the graph.

Throws:

GraphException

postProcess

GraphSteps postProcess(List<GraphStep> steps)

Deprecated.

Gives the GraphStepFactory a chance to add pre or post-steps for validation and similar activities.

Parameters:

steps - Non-null list of steps which are to be post-processed.

Returns:

Either the original unmodified list, possibly with additions or deletions, or a new list entirely.
