VariableReference

public VariableReference(java.lang.String name)

alternative to using a Builder for convenience

Parameters:

name - of the variable

Method Detail

getName

public java.lang.String getName()

Specified by:

getName in interface NamedNode<VariableReference>

Returns:

the name of this node

getChildren

public java.util.List<Node> getChildren()

Specified by:

getChildren in interface Node<VariableReference>

Returns:

a list of the children of this node

isEqualTo

public boolean isEqualTo(Node o)

Description copied from interface: Node

Compares just the content and not the children.

Specified by:

isEqualTo in interface Node<VariableReference>

Parameters:

o - the other node to compare to

Returns:

isEqualTo

deepCopy

public VariableReference deepCopy()

Specified by:

deepCopy in interface Node<VariableReference>

Returns:

a deep copy of this node

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

accept

public TraversalControl accept(TraverserContext<Node> context,
                               NodeVisitor visitor)

Description copied from interface: Node

Double-dispatch entry point. A node receives a Visitor instance and then calls a method on a Visitor that corresponds to a actual type of this Node. This binding however happens at the compile time and therefore it allows to save on rather expensive reflection based instanceOf check when decision based on the actual type of Node is needed, which happens redundantly during traversing AST. Additional advantage of this pattern is to decouple tree traversal mechanism from the code that needs to be executed when traversal "visits" a particular Node in the tree. This leads to a better code re-usability and maintainability.

Specified by:

accept in interface Node<VariableReference>

Parameters:

context - TraverserContext bound to this Node object

visitor - Visitor instance that performs actual processing on the Nodes(s)

Returns:

Result of Visitor's operation. Note! Visitor's operation might return special results to control traversal process.
