Adjust an existing graph traversal policy so that orphaned model objects will always or never be included, according to their type.

Parameters:

graphPolicy - the graph policy to adjust

graphPathBean - the graph path bean, for converting class names to the actual classes

startFrom - the model object types to from which to start inclusion, may not be empty or null

startAction - the action associated with nodes qualifying as start objects

permissionsOverrides - where to note for which startFrom objects permissions are not to be checked

Returns:

the adjusted graph policy

Throws:

ome.services.graphs.GraphException - if no start classes are named

getSkipHeadPolicyPerform

public static ome.services.graphs.GraphPolicy getSkipHeadPolicyPerform(ome.services.graphs.GraphPolicy graphPolicy,
                                                                       com.google.common.collect.SetMultimap<java.lang.String,java.lang.Long> permissionsOverrides)

Adjust an existing graph traversal policy so that for specific model objects permissions are not checked.

Parameters:

graphPolicy - the graph policy to adjust

permissionsOverrides - for which model objects permissions are not to be checked

Returns:

the adjusted graph policy
