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.

toString

public String toString()

Overrides:

toString in class SimpleNode

toGetSourceString

public String toGetSourceString(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:

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

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 SimpleNode

Parameters:

context - the OgnlContext within which to perform the operation.

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

Returns:

Literal java string representation of an object set.
