Method Summary

Modifier and Type	Method	Description
void	endScriptDecl()	Notification of the end of a script declaration.
void	scriptFieldDecl(int access, String type, String name, Object value)	Notification of a script's field declaration.
void	startScriptDecl()	Notification of the start of a script declaration.

Method Details

startScriptDecl

void startScriptDecl()
              throws SAVException,
VRMLException

Notification of the start of a script declaration. All calls between now and the corresponding endScriptDecl() call belong to this script node. This method will be called after the ContentHandler startNode() method call. All DEF information is contained in that method call and this just signifies the start of script processing so that we know to treat the field parsing callbacks a little differently.

Throws:

SAVException - This call is taken at the wrong time in the structure of the document.

VRMLException - This call is taken at the wrong time in the structure of the document.

endScriptDecl

void endScriptDecl()
            throws SAVException,
VRMLException

Notification of the end of a script declaration. This is guaranteed to be called before the ContentHandler endNode() callback.

Throws:

SAVException - This call is taken at the wrong time in the structure of the document.

VRMLException - This call is taken at the wrong time in the structure of the document.

scriptFieldDecl

void scriptFieldDecl(int access,
 String type,
 String name,
 Object value)
              throws SAVException,
VRMLException

Notification of a script's field declaration. This is used for all fields except url, mustEvaluate and directOutput fields. These fields use the normal field callbacks of ContentHandler.

If the current parsing is in a proto and the field "value" is defined with an IS statement then the value returned here is null. There will be a subsequent call to the ProtoHandlers protoIsDecl() method with the name of the field included.

Parameters:

access - The access type (eg exposedField, field etc)

type - The field type (eg SFInt32, MFVec3d etc)

name - The name of the field

value - The default value of the field as either String or String[]. Null if not allowed.

Throws:

SAVException - This call is taken at the wrong time in the structure of the document.

VRMLException - This call is taken at the wrong time in the structure of the document.
