Method Detail

eval

public java.lang.Object eval(NameSpace namespace)
                      throws EvalError
Evaluate the types. Note that type resolution does not require the interpreter instance.

Overrides:
eval in class SimpleNode
EvalError

jjtOpen

public void jjtOpen()
Description copied from interface: Node
This method is called after the node has been made the current node. It indicates that child nodes can now be added to it.

Specified by:
jjtOpen in interface Node

jjtClose

public void jjtClose()
Description copied from interface: Node
This method is called after all the child nodes have been added.

Specified by:
jjtClose in interface Node

jjtSetParent

public void jjtSetParent(Node n)
Description copied from interface: Node
This pair of methods are used to inform the node of its parent.

Specified by:
jjtSetParent in interface Node

jjtGetParent

public Node jjtGetParent()
Specified by:
jjtGetParent in interface Node

jjtAddChild

public void jjtAddChild(Node n,
                        int i)
Description copied from interface: Node
This method tells the node to add its argument to the node's list of children.

Specified by:
jjtAddChild in interface Node

jjtGetChild

public Node jjtGetChild(int i)
Description copied from interface: Node
This method returns a child node. The children are numbered from zero, left to right.

Specified by:
jjtGetChild in interface Node

getChild

public SimpleNode getChild(int i)

jjtGetNumChildren

public int jjtGetNumChildren()
Description copied from interface: Node
Return the number of children the node has.

Specified by:
jjtGetNumChildren in interface Node

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object

toString

public java.lang.String toString(java.lang.String prefix)

dump

public void dump(java.lang.String prefix)

prune

public void prune()
Detach this node from its parent. This is primarily useful in node serialization. (see BSHMethodDeclaration)


eval

public java.lang.Object eval(CallStack callstack,
                             Interpreter interpreter)
                      throws EvalError
This is the general signature for evaluation of a node.

EvalError

setSourceFile

public void setSourceFile(java.lang.String sourceFile)
Set the name of the source file (or more generally source) of the text from which this node was parsed.


getSourceFile

public java.lang.String getSourceFile()
Get the name of the source file (or more generally source) of the text from which this node was parsed. This will recursively search up the chain of parent nodes until a source is found or return a string indicating that the source is unknown.


getLineNumber

public int getLineNumber()
Get the line number of the starting token


getText

public java.lang.String getText()
Get the text of the tokens comprising this node.
