getSkipHeadPolicySkip

public static GraphPolicy getSkipHeadPolicySkip(GraphPolicy graphPolicy,
                                                GraphPathBean graphPathBean,
                                                Collection<String> startFrom,
                                                GraphPolicy.Action startAction,
                                                com.google.common.collect.SetMultimap<String,Long> permissionsOverrides)
                                         throws GraphException

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:

GraphException - if no start classes are named

getSkipHeadPolicyPerform

public static GraphPolicy getSkipHeadPolicyPerform(GraphPolicy graphPolicy,
                                                   com.google.common.collect.SetMultimap<String,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
