Constructor Detail

ResourceTypeManager

public ResourceTypeManager(Map<Name,TypeSet<T>> resourceTypeSetMap)
                    throws IllegalStateException

Adds the given types to the manager, building a graph to represent the type hierarchy.

Parameters:

resourceTypeSetMap - a full set of types to use

Throws:

IllegalStateException - if types are missing (e.g. a type needs a parent but the parent is missing)

ResourceTypeManager

public ResourceTypeManager(Map<Name,TypeSet<T>> resourceTypeSetMap,
                           Collection<Name> setsToUse)
                    throws IllegalStateException

Adds the given types to the manager, building a graph to represent the type hierarchy.

Parameters:

resourceTypeSetMap - a full set of types

setsToUse - optional set of type names that the manager to care about - it will ignore others it finds. If null, then the full set is used (by "full set" it means the resourceTypeSetMap param).

Throws:

IllegalStateException - if types are missing (e.g. a type needs a parent but the parent is missing)

Method Detail

getResourceTypesGraph

public org.jgrapht.graph.ListenableDirectedGraph<T,org.jgrapht.graph.DefaultEdge> getResourceTypesGraph()

Returns:

the internal graph of the resource types being managed. Use with caution, changes to this graph are backed by this manager.

getBreadthFirstIterator

public org.jgrapht.traverse.BreadthFirstIterator<T,org.jgrapht.graph.DefaultEdge> getBreadthFirstIterator()

Returns an iterator that let's you walk the tree of resource types breadth-first. Do NOT modify the resource type graph while iterating.

Returns:

an iterator that iterates the resource type graph breadth-first

getDepthFirstIterator

public org.jgrapht.traverse.DepthFirstIterator<T,org.jgrapht.graph.DefaultEdge> getDepthFirstIterator()

Returns an iterator that let's you walk the tree of resource types depth-first. Do NOT modify the resource type graph while iterating.

Returns:

an iterator that iterates the resource type graph depth-first

getRootResourceTypes

public Set<T> getRootResourceTypes()

Returns resource types that are at the top of the hierarchy (that is, they do not have any parent types).

Returns:

root types

getChildren

public Set<T> getChildren(T resourceType)

Returns the direct child types of the given resource type.

Parameters:

resourceType - the type whose children are to be returned

Returns:

the direct children of the given resource type

getParents

public Set<T> getParents(T resourceType)

Returns the direct parent types of the given resource type.

Parameters:

resourceType - the type whose parents are to be returned

Returns:

the direct parents of the given resource type

getAllResourceTypes

public Set<T> getAllResourceTypes()

Returns an unordered set of all resource types currently being managed.

Returns:

all resource types
