Method Details

getProtoName

public String getProtoName()
                    throws InvalidNodeException

Description copied from interface: X3DProtoDeclaration

Get the type of this node. The string returned should be the name of the VRML node or the name of the proto instance this node represents.

Specified by:

getProtoName in interface X3DProtoDeclaration

Returns:

The type of this node.

Throws:

InvalidNodeException - The node has had it's resources disposed of

See Also:

• X3DProtoDeclaration.getProtoName()

getNodeType

public int[] getNodeType()
                  throws InvalidNodeException

Description copied from interface: X3DProtoDeclaration

Fetch the type of this proto. The proto's type is defined by the first child node in the body, in accordance with the X3D specification.

The types values are provided in the array of values. There is no specific order of the returned types. It is expected that most node types, which only descend from a single parent type would return an array of length 1.

Specified by:

getNodeType in interface X3DProtoDeclaration

Returns:

The primary type(s) of this node

Throws:

InvalidNodeException - The node has had it's resources disposed of

See Also:

• X3DProtoDeclaration.getNodeType()

getFieldDefinitions

public X3DFieldDefinition[] getFieldDefinitions()
                                         throws InvalidNodeException

Description copied from interface: X3DProtoDeclaration

Get the list of fields that this node contains. This will return one definition for each field regardless of whether it is eventIn/Out, exposedField or field access type.

Specified by:

getFieldDefinitions in interface X3DProtoDeclaration

Returns:

The definitions for all fields of this node

Throws:

InvalidNodeException - The node has had it's resources disposed of

See Also:

• X3DProtoDeclaration.getFieldDefinitions()

createInstance

public X3DProtoInstance createInstance()
                                throws InvalidNodeException

Description copied from interface: X3DProtoDeclaration

Create an instance of this proto that may be used at runtime.

Specified by:

createInstance in interface X3DProtoDeclaration

Returns:

An instance of this proto to work with

Throws:

InvalidNodeException - The node has had it's resources disposed of

See Also:

• X3DProtoDeclaration.createInstance()

dispose

public void dispose()
             throws InvalidNodeException

Description copied from interface: X3DProtoDeclaration

Dispose of this node's resources. This is used to indicate to the browser that the java side of the application does not require the resources represented by this node. The browser is now free to do what it likes with the node.

This in no way implies that the browser is to remove this node from the scene graph, only that the java code is no longer interested in this particular node through this reference.

Once this method has been called, any further calls to methods of this instance of the class is shall generate an InvalidNodeException.

Specified by:

dispose in interface X3DProtoDeclaration

Throws:

InvalidNodeException - The node is no longer valid and can't be disposed of again.
