Constructor Detail

DivideExpr

public DivideExpr()
The noarg constructor is needed for ANTLR support and deserialization. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.


DivideExpr

public DivideExpr(antlr.Token token)
The noarg constructor is needed for ANTLR support. The caller must make sure to set the ANTLR tree structure himself or, call setChildren optionally.

Method Detail

arrive

public void arrive(NodeVisitor visitor)
Delegates to the argument visitor.

Specified by:
arrive in interface Node
Overrides:
arrive in class NodeImpl
Parameters:
visitor - the node visitor

leave

public java.lang.Object leave(NodeVisitor visitor,
                              java.lang.Object[] results)
Delegates to the argument visitor.

Specified by:
leave in interface Node
Overrides:
leave in class NodeImpl
Parameters:
visitor - the node visitor
results - the result array
Returns:
the object returned by the visitor instance

walkNextChild

public boolean walkNextChild(NodeVisitor visitor,
                             java.lang.Object resultOfPreviousChild,
                             int indexOfNextChild)
Delegates to the argument visitor.

Specified by:
walkNextChild in interface Node
Overrides:
walkNextChild in class NodeImpl
Parameters:
visitor - the node visitor
resultOfPreviousChild - the result computed by leaving the previous child node
indexOfNextChild - the index in the children array of the next child to walk
Returns:
the boolean value returned by the visitor instance
