Method Detail

getParentElement

public MetadataElement getParentElement()

equals

public boolean equals(Object object)

Overrides:

equals in class Object

acceptVisitor

public void acceptVisitor(ProductVisitor visitor)

Accepts the given visitor. This method implements the well known 'Visitor' design pattern of the gang-of-four. The visitor pattern allows to define new operations on the product data model without the need to add more code to it. The new operation is implemented by the visitor.

The method simply calls visitor.visit(this).

Specified by:

acceptVisitor in class DataNode

Parameters:

visitor - the visitor

createDeepClone

public MetadataAttribute createDeepClone()
