Constructor Detail

ASTAnd

public ASTAnd(int id)
TODO: javadoc

Parameters:
id - the id

              int id)
TODO: javadoc

Parameters:
p - the parser
id - the id
Method Detail

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
Overrides:
jjtClose in class SimpleNode

getValueBody

protected Object getValueBody(OgnlContext context,
                              Object source)
                       throws OgnlException
Description copied from class: SimpleNode
Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.

Specified by:
getValueBody in class SimpleNode
Throws:
OgnlException

setValueBody

protected void setValueBody(OgnlContext context,
                            Object target,
                            Object value)
                     throws OgnlException
Description copied from class: SimpleNode
Subclasses implement this method to do the actual work of setting the appropriate value in the target object. The default implementation throws an InappropriateExpressionException, meaning that it cannot be a set expression.

Overrides:
setValueBody in class SimpleNode
Throws:
OgnlException

getExpressionOperator

public String getExpressionOperator(int index)
Overrides:
getExpressionOperator in class ExpressionNode

getGetterClass

public Class getGetterClass()
Description copied from class: BooleanExpression
The type returned from the expression - if any.

Specified by:
getGetterClass in interface NodeType
Overrides:
getGetterClass in class BooleanExpression
Returns:
The type.

toGetSourceString

public String toGetSourceString(OgnlContext context,
                                Object target)
Description copied from class: BooleanExpression
Expected to return a java source representation of itself such that it could be turned into a literal java expression to be compiled and executed for ExpressionAccessor.get(OgnlContext, Object) calls.

Specified by:
toGetSourceString in interface JavaSource
Overrides:
toGetSourceString in class BooleanExpression
Returns:
Literal java string representation of an object get.

toSetSourceString

public String toSetSourceString(OgnlContext context,
                                Object target)
Description copied from interface: JavaSource
Expected to return a java source representation of itself such that it could be turned into a literal java expression to be compiled and executed for ExpressionAccessor.get(OgnlContext, Object) calls.

Specified by:
toSetSourceString in interface JavaSource
Overrides:
toSetSourceString in class ExpressionNode
Returns:
Literal java string representation of an object get.

accept

public <R,P> R accept(NodeVisitor<? extends R,? super P> visitor,
                      P data)
         throws OgnlException
Description copied from interface: Node
Supports the Visitor pattern. The method which corresponds to the runtime type of this Node will be called.

Type Parameters:
R - The return type of the visitor.visit method.
P - The type of the second parameter type.
Parameters:
visitor - The visitor to accept.
data - The second parameter to pass through to visitor.visit
Returns:
the value returned by visitor.visit
Throws:
OgnlException
