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 java.lang.Object getValueBody(OgnlContext context,
                                        java.lang.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,
                            java.lang.Object target,
                            java.lang.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 java.lang.String getExpressionOperator(int index)

Overrides:

getExpressionOperator in class ExpressionNode

getGetterClass

public java.lang.Class getGetterClass()

Description copied from interface: NodeType

The type returned from the expression - if any.

Specified by:

getGetterClass in interface NodeType

Overrides:

getGetterClass in class BooleanExpression

Returns:

The type.

toGetSourceString

public java.lang.String toGetSourceString(OgnlContext context,
                                          java.lang.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:

toGetSourceString in interface JavaSource

Overrides:

toGetSourceString in class BooleanExpression

Returns:

Literal java string representation of an object get.

toSetSourceString

public java.lang.String toSetSourceString(OgnlContext context,
                                          java.lang.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.
