Package ariba.util.expr

Interface Summary

ClassResolver	This interface defines an object that will resolve a class from a string and a ognl context table.
ExprContext.ExtensibleContext
MemberAccess	This interface provides a hook for preparing for accessing members of objects.
MethodAccessor	This interface defines methods for callinig methods in a target object.
Node	JJTree interface for AST nodes, as modified to handle the AribaExpr operations getValue and setValue.
NullHandler	Interface for handling null results from Chains.
PropertyAccessor	This interface defines methods for setting and getting a property from a target object.
Symbol
TypeConverter	Interface for accessing the type conversion facilities within a context.

Class Summary

AribaExprEvaluator	Factory for Expr-based expressions
AribaExprEvaluator.Expression
AribaExprEvaluator.NodeVisitor
ASTNodeVisitor
ClassNameToFirstParameterAdapter	Takes care of getting the first argument from the methodInfo and passing that during runtime based on the annotation.
ConvertibleFieldValue
DefaultClassResolver	Default class resolution.
DefaultMemberAccess	This class provides methods for setting up and restoring access in a Field.
DefaultTypeConverter	Default type conversion.
DynamicSubscript	This class has predefined instances that stand for special "dynamic subscripts" for getting at the first, middle, or last elements of a list.
EnumerationIterator	Object that implements Iterator from an Enumeration
Environment
Evaluation	An Evaluation is and object that holds a node being evaluated and the source from which that node will take extract its value.
EvaluationPool
Expr	This class provides static methods for parsing and interpreting AribaExpr expressions.
ExprContext	This class defines the execution context for an AribaExpr expression
ExpressionNode
ExprInvokePermission	BasicPermission subclass that defines a permission token for invoking methods within Expr.
ExprOps	This is an abstract class with static methods that define the operations of AribaExpr.
ExprRuntime	This is an abstract class with static methods that define runtime caching information in AribaExpr.
FieldValue_ConvertibleFieldValue
IntHashMap	A Map that uses ints as the keys.
IntHashMap.Entry
IteratorEnumeration	Maps an Iterator to an Enumeration
Log
ObjectArrayPool
ObjectArrayPool.SizePool
ObjectIndexedPropertyDescriptor	PropertyDescriptor subclass that describes an indexed set of read/write methods to get a property.
ObjectMethodAccessor	Implementation of PropertyAccessor that uses reflection on the target object's class to find a field or a pair of set/get methods with the given property name.
ObjectNullHandler	Implementation of NullHandler that returns null in all cases, so that NullPointerException will be thrown by the caller.
SafeSymbolValidator
SemanticRecord
SimpleNode
SymbolTable
SymbolValidator
TypeChecker
TypeConversionHelper

Exception Summary

ExpressionSyntaxException	Exception thrown if a malformed OGNL expression is encountered.
ExprException	Superclass for Expr exceptions, incorporating an optional encapsulated exception.
InappropriateExpressionException	Exception thrown if an OGNL expression is evaluated in the wrong context; the usual case is when an expression that does not end in a property reference is passed to setValue.
MethodFailedException	Exception thrown if a method or constructor call fails.
NoSuchPropertyException	Exception thrown if a property is attempted to be extracted from an object that does not have such a property.
