Method Detail

addBaseNode

public BaseNode addBaseNode(java.lang.String key,
                            java.lang.Class type)

Description copied from interface: DataStructureConfiguration

Registers a base node that does not depend on any other node and holds a value of the given type.

Specified by:

addBaseNode in interface DataStructureConfiguration

Parameters:

key - the key of the node to create

type - the type that this node holds

Returns:

the node that has been added

addAspectNode

public AspectNode addAspectNode(java.lang.String key,
                                java.lang.String sourceKey,
                                java.lang.Class sourceType,
                                java.lang.String aspectName,
                                java.lang.Class aspectType)

Description copied from interface: DataStructureConfiguration

Registers an aspect node that depends on one source value and provides the value of an aspect of that value. This is usally an attribute of an object.

Specified by:

addAspectNode in interface DataStructureConfiguration

Parameters:

key - the key of the node to create

sourceKey - the key of the node that holds the source value

sourceType - the type of the value that is expected from the source node

aspectName - the name of the aspect, i.e. the name of the attribute of the source value

aspectType - the type that the aspect guarantees to have. This is usually the type of the attribute but it may be narrowed to a type that is assignable to the type of the attribute.

Returns:

the node that has been added

addComputedNode

public ComputedNode addComputedNode(java.lang.String key,
                                    java.lang.String[] sourceKeys,
                                    Computation computation)

Description copied from interface: DataStructureConfiguration

Registers a computed node that depends on one or more source values and is defined by a Computation. When computed, the values of the nodes that are defined by the source keys are passed to the Computation in the order the keys are defined in this method.

Specified by:

addComputedNode in interface DataStructureConfiguration

Parameters:

key - the key of the node to create

sourceKeys - the keys of the nodes in the order that the computation depends on

computation - the computation rule

Returns:

the node that has been added

addIndexedNode

public IndexedNode addIndexedNode(java.lang.String key,
                                  java.lang.String sourceKey,
                                  java.lang.Class sourceType,
                                  java.lang.Class indexType,
                                  java.lang.Class type)

Description copied from interface: DataStructureConfiguration

Registers an indexed node that depends on one source value and provides indexed access to the value. The source value must be a collection of data of some type supported by the DataManagerPlugIns of the DataManager.

Specified by:

addIndexedNode in interface DataStructureConfiguration

Parameters:

key - the key of the node to create

sourceKey - the key of the source node that provides the collection

sourceType - the type of the source value

indexType - the type of the index values

type - the type of the values in the collection

Returns:

the node that has been added

hasNode

public boolean hasNode(java.lang.String key)

Description copied from interface: DataConfiguration

Tests whether a node has been configured

Specified by:

hasNode in interface DataConfiguration

Parameters:

key - the key of the node

Returns:

true iff the node has been defined

getNode

Description copied from interface: DataConfiguration

Returns the node configured for the given key

Specified by:

getNode in interface DataConfiguration

Parameters:

key - the key of the node

Returns:

the node for the key

removeNode

public Node removeNode(java.lang.String key)

Description copied from interface: DataConfiguration

Removes a node and all nodes that depend on it

Specified by:

removeNode in interface DataConfiguration

Parameters:

key - the key of the node to remove

Returns:

the node that has been removed

addNode

public void addNode(Node node)

Description copied from interface: DataConfiguration

Configures a new node

Specified by:

addNode in interface DataConfiguration

Parameters:

node - the node that should be added

getNodeKeys

public java.util.Set getNodeKeys()

Specified by:

getNodeKeys in interface DataConfiguration

Returns:

the set of the keys of all nodes.
