Method Detail

init

void init(java.lang.String className,
          java.lang.String fieldName)

Called from parser action.

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

Parameters:

context - the OgnlContext within which to perform the operation.

source - the Object from which to get the value body.

Returns:

the value body from the source (as appropriate within the provided context).

Throws:

OgnlException - if the value body get fails.

isNodeConstant

public boolean isNodeConstant(OgnlContext context)
                       throws OgnlException

Description copied from class: SimpleNode

Returns true iff this node is constant without respect to the children.

Overrides:

isNodeConstant in class SimpleNode

Parameters:

context - the OgnlContext within which to perform the operation.

Returns:

true if this node is a constant, false otherwise.

Throws:

OgnlException - if the check fails.

getFieldClass

private java.lang.Class<?> getFieldClass(OgnlContext context)
                                  throws OgnlException

Throws:

OgnlException

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

Returns:

The type.

getSetterClass

public java.lang.Class<?> getSetterClass()

Description copied from interface: NodeType

The type used to set the value - if any.

Specified by:

getSetterClass in interface NodeType

Returns:

The type.

toString

public java.lang.String toString()

Overrides:

toString in class SimpleNode

toGetSourceString

public java.lang.String toGetSourceString(OgnlContext context,
                                          java.lang.Object target)

Description copied from interface: JavaSource

Specified by:

toGetSourceString in interface JavaSource

Overrides:

toGetSourceString in class SimpleNode

Parameters:

context - the OgnlContext within which to perform the operation.

target - the Object from which to retrieve the get source string.

Returns:

Literal java string representation of an object get.

toSetSourceString

                                          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
