Class NullValueImpl

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<RealValue>, java.lang.Iterable<java.lang.Object>, BagValue, CollectionValue, IntegerValue, NullValue, ObjectValue, OCLValue, OrderedCollectionValue, OrderedSetValue, RealValue, SequenceValue, SetValue, TupleValue, UniqueCollectionValue, UnlimitedValue, Value

public class NullValueImpl
extends UndefinedValueImpl
implements NullValue

An InvalidValueException wraps an InvalidValue and is used to return the InvalidValue to the caller. Exceptions are a is thrown when an Invalid Value arises during an evaluation, and when no EvaluationEnvironment is available to support throwing an InvalidEvaluationException. When such an environment is available the InvalidValueException is rethrown as an InvalidEvaluationException. * @generated NOT

asEcoreObject

@Deprecated
public java.util.List<java.lang.Object> asEcoreObject()

Deprecated.

Description copied from interface: Value

Return the Ecore representation of this value.

An thrown exception for an invalid OCL value.

Java-null for a null OCL value

Objects for other things

Specified by:

asEcoreObject in interface CollectionValue

Specified by:

asEcoreObject in interface Value

asEcoreObject

public java.util.List<java.lang.Object> asEcoreObject(@NonNull
                                                      IdResolver idResolver)

Specified by:

asEcoreObject in interface CollectionValue

Specified by:

asEcoreObject in interface Value

asElement

public DomainElement asElement()

Specified by:

asElement in interface Value

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

getType

@NonNull
public DomainType getType(@NonNull
                                  DomainStandardLibrary standardLibrary)

getTypeId

@NonNull
public OclVoidTypeId getTypeId()

Description copied from interface: Value

Return the type of this value determined from its construction context. In the case of collections this may differ from the actual type.

Specified by:

getTypeId in interface CollectionValue

Specified by:

getTypeId in interface NullValue

Specified by:

getTypeId in interface TupleValue

Specified by:

getTypeId in interface Value

Specified by:

getTypeId in class UndefinedValueImpl

Returns:

its type

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

intValue

public int intValue()

Specified by:

intValue in interface IntegerValue

isInvalid

public boolean isInvalid()

Specified by:

isInvalid in interface Value

oclEquals

public boolean oclEquals(@NonNull
                         OCLValue thatValue)

Description copied from interface: OCLValue

Return true if this is an equivalent OCL value to thatValue.

Note that the caller must check that the argument is an OCLValue and should also check for the shortcut case that this == thatValue. Implementations are therefore wasting time if they re-implement the shortcut.

Specified by:

oclEquals in interface OCLValue

oclHashCode

public int oclHashCode()

Specified by:

oclHashCode in interface OCLValue

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Throwable
