public abstract class JexlNode
extends SimpleNode

Base class for parser nodes - holds an 'image' of the token for later use.

Since:

2.0

JexlNode

public JexlNode(int id)

JexlNode

public JexlNode(Parser p,
                int id)

jjtSetFirstToken

public void jjtSetFirstToken(Token t)

jjtSetLastToken

public void jjtSetLastToken(Token t)

jexlInfo

public JexlInfo jexlInfo()

Gets the associated JexlInfo instance.

Returns:

the info

clearCache

public void clearCache()

Clears any cached value of type JexlProperty{G,S}et or JexlMethod.

This is called when the engine detects the evaluation of a script occurs with a class loader different that the one that created it.

isConstant

public boolean isConstant()

Whether this node is a constant node Its value can not change after the first evaluation and can be cached indefinitely.

Returns:

true if constant, false otherwise

isConstant

protected boolean isConstant(boolean literal)

isLeftValue

public boolean isLeftValue()

Whether this node is a left value.

Returns:

true if node is assignable, false otherwise
