Package ariba.util.fieldvalue Description

The core property access mechanism used by AribaWeb bindings and the Expr expression language. FieldValue provides a uniform Map-like (get/set) interface to objects of various sorts (POJOs, Maps, scriptable objects, ...). FieldValue is implemented as a ClassExtension, meaning that implementation of the FieldValue abstraction can be done outside of the target classes, thereby allowing implementations on existing core Java classes (Object, Map, etc).

FieldValue provides optimized access for field paths (e.g. "employee.manager.name") via the FieldPath class. FieldPaths are pre-parsed and cache the FieldValueAccessor to which they last (dynamically) resolved, thereby avoiding future lookup/reflection on repeated use.

Interface Summary

Extensible	The Extensible interface can be implemented when a given class wants to provide dynamically added fields.
FieldValueAccessor	The FieldValueAccessor class is a base class that serves as the base for all FieldValueAccessors.
FieldValueGetter	The FieldValueGetter class is an abstract class that serves as the base for all FieldValueGetters.
FieldValueSetter	The FieldValueSetter class is an abstract class that serves as the base for all FieldValueSetters.

Class Summary

AWPrimitiveArrayClassExtension
BaseAccessor	The BaseAccessor class is a base class that serves as the base for all FieldValueAccessors.
ClassExtensionGetter	A special FieldValueAccessor subclass which supports the use of the FieldValue subsystem to invoke ClassExtension methods.
ClassExtensionSetter	A special FieldValueAccessor subclass which supports the use of the FieldValue subsystem to invoke ClassExtension methods.
CompiledAccessor
CompiledAccessorFactory	CompiledAccessorFactory creates instances of CompiledAccessor given either a java.lang.reflect.Field or java.lang.reflect.Method.
CompiledAccessorFactory.ByteArrayClassLoader
Expression	Abstract representation of an expression in an unspecified expression language.
ExpressionEvaluator	Abstraction of a factory class for creating Expressions.
ExtensibleFieldValueAccessor	FieldValue_Extensible provides an implementation of the FieldValue interface for the Extensible interface.
FieldInfo
FieldInfo.Collection
FieldPath	The FieldPath class is an object representation of a dotted fieldPath.
FieldValue	The FieldValue class defines a ClassExtension for JavaBean-like property access on target objects.
FieldValue_Extensible	FieldValue_Extensible provides an implementation of the FieldValue interface for the Extensible interface.
FieldValue_JavaHashtable	The JavaHashtableFieldValueClassExtension converts the behavior of java.util.Map so that using fieldValue accessors on them does not attempt to access the fields or methods of the Map itself, but will access the values stored in the Map.
FieldValue_Object	The FieldValue_Object class extension is the default implementation of the FieldValue interface.
FieldValueAccessorUtil	Several static methods which are used in various places within the FieldValue subsystem to handle certain reflection operations more gracefully.
OrderedList	Sample Usage: int index = OrderedList.get(someList).indexOf(someList, someObject);
OrderedList_AribaVector
OrderedList_Collection	Partial implementation of OrderedList protocol for Collections (Useful for Sets)
OrderedList_JavaVector
OrderedList_List
OrderedList_ObjectArray
ReflectionMethodAccessor	The ReflectionMethodAccessor is a wrapper for java.lang.reflect.Method and provides a uniform interface so that users needn't know if the accesor they're dealing with is either a Method or a Field.
ReflectionMethodGetter	The ReflectionMethodGetter is a wrapper for java.lang.reflect.Method and provides a uniform interface so that users needn't know if the accesor they're dealing with is either a Method or a Field.
ReflectionMethodSetter	The ReflectionMethodSetter is a wrapper for java.lang.reflect.Method and provides a uniform interface so that users needn't know if the accesor they're dealing with is either a Method or a Field.
RelationshipField	Used to manipulate Collection-typed properties.
RelationshipField.Adder

Exception Summary

ExpressionEvaluatorException	An Exception class for the ExpressionEvaluator class.
ExpressionException	Represents an exceptional condition that has ocurred in some way related to Expressions.
FieldValueException	The FieldValueException class provides a simple runtime exception for all the various problems which might occur within the FieldValue dispatch mechanism.
