Method Summary
Modifier and TypeMethodDescriptionThe type returned from the expression - if any.int
getIndexedPropertyType
(OgnlContext context, Object source) Returns true if this property is described by an IndexedPropertyDescriptor and that if followed by an index specifier it will call the index get/set methods rather than go through property accessors.getProperty
(OgnlContext context, Object source) The type used to set the value - if any.protected Object
getValueBody
(OgnlContext context, Object source) Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.boolean
Returns true if this property is itself an index reference.boolean
isNodeSimpleProperty
(OgnlContext context) void
setIndexedAccess
(boolean value) protected void
setValueBody
(OgnlContext context, Object target, Object value) Subclasses implement this method to do the actual work of setting the appropriate value in the target object.toGetSourceString
(OgnlContext context, Object target) 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 forExpressionAccessor.get(OgnlContext, Object)

setIndexedAccess
public void setIndexedAccess(boolean value) -
isIndexedAccess
public boolean isIndexedAccess()Returns true if this property is itself an index reference. -
getIndexedPropertyType
Returns true if this property is described by an IndexedPropertyDescriptor and that if followed by an index specifier it will call the index get/set methods rather than go through property accessors.- Throws:
OgnlException
-
getProperty
- Throws:
OgnlException
-
getValueBody
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 classSimpleNode
- Throws:
OgnlException
-
setValueBody
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 anInappropriateExpressionException
, meaning that it cannot be a set expression.- Overrides:
