public class OCLConstraintCondition

extends 
OCLCondition

A specialized OCL condition class that is used to apply boolean-valued OCL expressions to EObjects. These are commonly used to express invariant constraints; they are not typically evaluated but are usually checked for isSatisfied(EObject).

Field Summary

Field Detail

NULL_CONDITION

public static final 
OCLConstraintCondition NULL_CONDITION
Deprecated. 
A simple condition constant that represents an OCLConstraintCondition that is always satisfied. Functions as a literal "true".

Constructor Detail

OCLConstraintCondition

public OCLConstraintCondition(
String oclExpressionString,
                              
EClass contextEObjectType,
                              
IEStructuralFeatureValueGetter eStructuralFeatureValueGetter)
Deprecated. 
Initializes a constraint condition with an OCL expression string, an EClass representing the EObject type which the OCL expression uses as a context, and an IEStructuralFeatureValueGetter to use to get values of StructuralFeatures referenced by the OCL expression. It defaults to using PruneHandler.NEVER to consult for pruning.

NOTE: if contextEObjectType is null, then this becomes a context-free OCL constraint condition.

Parameters:
oclExpressionString - The OCL expression to apply when evaluating this OCLCondition
contextEObjectType - The EClass representing the OCL context classifier. Use null to create a context-free OCLCondition.
eStructuralFeatureValueGetter - The strategy for accessing structural feature values. It serves as a layer of indirection to allow clients to intervene between this condition object and the way it extracts the StructuralFeatures' values so as to allow for manipulation of such values before subjecting them to evaluation by the OCL interpreter.

OCLConstraintCondition

public OCLConstraintCondition(
String oclExpressionString,
                              
EClass contextEObjectType)
Deprecated. 
Initializes a constraint condition with an OCL expression string, an EClass representing the EObject type which the OCL expression uses as a context, and an IEStructuralFeatureValueGetter to use to get values of StructuralFeatures referenced by the OCL expression. It defaults to using PruneHandler.NEVER to consult for pruning.

NOTE: if contextEObjectType is null, then this becomes a context-free OCL constraint condition.

This constructor implicitly uses the default EStructuralFeatureValueGetter to access any EAttributes or EReferences of EObjects.

Parameters:
oclExpressionString - The OCL expression to apply when evaluating this OCLCondition
contextEObjectType - The EClass representing the OCL context classifier. Use null to create a context-free OCLCondition.

OCLConstraintCondition

public OCLConstraintCondition(
String oclExpressionString,
                              
EClass contextEObjectType,
                              
IEStructuralFeatureValueGetter eStructuralFeatureValueGetter,
                              
PruneHandler pruneHandler)
Deprecated. 
Initializes a constraint condition with an OCL expression string, an EClass representing the EObject type which the OCL expression uses as a context, an IEStructuralFeatureValueGetter to use to get values of StructuralFeatures referenced by the OCL expression, and a PruneHandler to consult for pruning the content tree.

NOTE: if contextEObjectType is null, then this becomes a context-free OCL constraint condition.

Parameters:
oclExpressionString - The OCL expression to apply when evaluating this OCLCondition
contextEObjectType - The EClass representing the OCL context classifier. Use null to create a context-free OCLCondition.
eStructuralFeatureValueGetter - The strategy for accessing structural feature values. It serves as a layer of indirection to allow clients to intervene between this condition object and the way it extracts the StructuralFeatures' values so as to allow for manipulation of such values before subjecting them to evaluation by the OCL interpreter.
pruneHandler - The PruneHandler to consult when pruning

OCLConstraintCondition

public OCLConstraintCondition(
Query oclQuery,
                              
EClass contextEObjectType,
                              
IEStructuralFeatureValueGetter eStructuralFeatureValueGetter,
                              
PruneHandler pruneHandler)
Deprecated. 
Initializes a constraint condition with a compiled OCL query, an EClass representing the EObject type which the OCL expression uses as a context, an IEStructuralFeatureValueGetter to use to get values of StructuralFeatures referenced by the OCL expression, and a PruneHandler to consult for pruning the content tree.

Parameters:
oclQuery - The OCL query to apply when evaluating this OCLCondition
contextEObjectType - The EClass representing the OCL context classifier. Must not be null.
eStructuralFeatureValueGetter - The strategy for accessing structural feature values. It serves as a layer of indirection to allow clients to intervene between this condition object and the way it extracts the StructuralFeatures' values so as to allow for manipulation of such values before subjecting them to evaluation by the OCL interpreter.
pruneHandler - The PruneHandler to consult when pruning

OCLConstraintCondition

public OCLConstraintCondition(
Query oclQuery,
                              
EClass contextEObjectType,
                              
PruneHandler pruneHandler)
Deprecated. 

Initializes a constraint condition with a compiled OCL query, an EClass representing the EObject type which the OCL expression uses as a context, an IEStructuralFeatureValueGetter to use to get values of StructuralFeatures referenced by the OCL expression, and a PruneHandler to consult for pruning the content tree.

This constructor implicitly uses the default EStructuralFeatureValueGetter to retrieve the values of an EObject's structural feature values.

Parameters:
oclQuery - The OCL query to apply when evaluating this OCLCondition
contextEObjectType - The EClass representing the OCL context classifier. Must not be null.
pruneHandler - The PruneHandler to consult when pruning
