All Implemented Interfaces:

Cloneable, OclRoot

public class OclAnyImpl

extends OclAny

This class represents the OCL type OclAny. It implements the properties defined for this type and gives access to fields of application objects using Java Reflection.

Field Detail

applicationObject

private Object applicationObject

the application object that is encapsulated by this instance of OclAnyImpl

featurelistener

private static FeatureListener featurelistener

Constructor Detail

OclAnyImpl

public OclAnyImpl(Object o)

A public constructor for OclAnyImpl. Applications using the OCL class library should use the factory methods of the class Ocl to create instances of OclAnyImpl.

OclAnyImpl

public OclAnyImpl(int dummy,
                  String reason)

constructor for the undefined OclAnyImpl

Method Detail

isEqualTo

public OclBoolean isEqualTo(Object o)

two OclAnyImpl objects are equal if their encapsulated application objects are identical (NOT equal)

Specified by:

isEqualTo in interface OclRoot

Specified by:

isEqualTo in class OclAny

isNotEqualTo

public OclBoolean isNotEqualTo(Object o)

Description copied from interface: OclRoot

Returns the negated result of isEqualTo.

Specified by:

isNotEqualTo in interface OclRoot

Overrides:

isNotEqualTo in class OclAny

Returns:

the negated result of isEqualTo

getFeature

public OclRoot getFeature(String attributeName)

Calls getFeatureQualified without qualifiers.

Specified by:

getFeature in interface OclRoot

Specified by:

getFeature in class OclAny

See Also:

getFeatureQualified(java.lang.String, java.lang.Object)

getFeatureQualified

public OclRoot getFeatureQualified(String attributeName,
                                   Object qualifier)

The attributes of application objects can be queried through this method. Due to restrictions of the Java language, only public fields can be queried.

Parameters:

attributeName - the name of the feature, as a java.lang.String

findMethod

public static Method findMethod(Class myclass,
                                String name,
                                Class[] params)

getFeature

public OclRoot getFeature(String methodName,
                          Object[] params)

To call side-effect free methods of an object, invoke this method with the method name as String and the appropriate parameters. This method does not enforce that only side-effect free methods are called.

If an exception occurs in the called method or in accessing it, an undefined value is returned.

getFeatureAsSequence

public OclSequence getFeatureAsSequence(String name)

equals

public boolean equals(Object o)

hashCode

public int hashCode()

toString

public String toString()

oclType

public OclType oclType()

This property is no longer present in OCL 1.3. In spite of this, the library contains this method. The problems that lead to its cancellation do not occur in this Java implementation.

Overrides:

oclType in class OclAny

getObject

public Object getObject()

Returns:

the application object encapsulated by this OclAnyImpl

setFeatureListener

public static void setFeatureListener(FeatureListener f)

clearFeatureListener

public static void clearFeatureListener()
