Constructor Detail

GreaterThanExpr

public GreaterThanExpr()

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.

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
