public SchemaTypeInformation()

Method Detail

getIdentifier

public String getIdentifier(Type type)

Returns a unique identifier for the given element.

Specified by:

getIdentifier in interface NodeInformation<Type>

Parameters:

type - The element.

Returns:

The unique identifier.

getParentIdentifiers

public List<String> getParentIdentifiers(Type root,
                                         Type type)

Returns the identifiers of the parents of the given element, in the order that decides precedence among them.

A List because the order is read: Dag.addNode(Object) takes the first parent when the DAG does not allow multiple inheritance, so which one comes first decides where the node is attached. A Set would leave that to the implementation's choice of collection.

Specified by:

getParentIdentifiers in interface NodeInformation<Type>

Parameters:

root - The root element of the DAG.

type - The element.

Returns:

The parent identifiers, most significant first.

getAccessType

public AccessType getAccessType(Type type)

Returns the AccessType of the given element.

Specified by:

getAccessType in interface TypeInformation<Type>

Parameters:

type - The element.

Returns:

The access type.

getRoot

public Type getRoot(AccessType accessType)

Returns the root element for a given AccessType.

Specified by:

getRoot in interface TypeInformation<Type>

Parameters:

accessType - The access type.

Returns:

The root element.
