Method Detail

getResult

OutputPin getResult()

Returns the value of the 'Result' containment reference.

This feature subsets the following features:

• 'Output'

The pin on which are put the objects participating in the association at the end not specified by the inputs.

Returns:

the value of the 'Result' containment reference.

See Also:

setResult(OutputPin), UMLPackage.getReadLinkAction_Result()

setResult

void setResult(OutputPin value)

Sets the value of the 'Result' containment reference.

Parameters:

value - the new value of the 'Result' containment reference.

See Also:

getResult()

createResult

OutputPin createResult(java.lang.String name,
                       Type type)

Creates a new OutputPin,with the specified 'Name', and 'Type', and sets the 'Result' containment reference.

Parameters:

name - The 'Name' for the new OutputPin, or null.

type - The 'Type' for the new OutputPin, or null.

Returns:

The new OutputPin.

getResult()

validateOneOpenEnd

boolean validateOneOpenEnd(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                           java.util.Map<java.lang.Object,java.lang.Object> context)

Exactly one link-end data specification (the 'open' end) must not have an end object input pin. self.endData->select(ed | ed.value->size() = 0)->size() = 1

Parameters:

diagnostics - The chain of diagnostics to which problems are to be appended.

context - The cache of context-specific information.

validateTypeAndOrdering

boolean validateTypeAndOrdering(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                                java.util.Map<java.lang.Object,java.lang.Object> context)

The type and ordering of the result output pin are same as the type and ordering of the open association end. let openend : AssociationEnd = self.endData->select(ed | ed.value->size() = 0)->asSequence()->first().end in self.result.type = openend.type and self.result.ordering = openend.ordering

Parameters:

diagnostics - The chain of diagnostics to which problems are to be appended.

context - The cache of context-specific information.

validateCompatibleMultiplicity

boolean validateCompatibleMultiplicity(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                                       java.util.Map<java.lang.Object,java.lang.Object> context)

The multiplicity of the open association end must be compatible with the multiplicity of the result output pin. let openend : AssociationEnd = self.endData->select(ed | ed.value->size() = 0)->asSequence()->first().end in openend.multiplicity.compatibleWith(self.result.multiplicity)

Parameters:

diagnostics - The chain of diagnostics to which problems are to be appended.

context - The cache of context-specific information.

validateNavigableOpenEnd

boolean validateNavigableOpenEnd(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                                 java.util.Map<java.lang.Object,java.lang.Object> context)

The open end must be navigable. let openend : AssociationEnd = self.endData->select(ed | ed.value->size() = 0)->asSequence()->first().end in openend.isNavigable()

Parameters:

diagnostics - The chain of diagnostics to which problems are to be appended.

context - The cache of context-specific information.

validateVisibility

boolean validateVisibility(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                           java.util.Map<java.lang.Object,java.lang.Object> context)

Visibility of the open end must allow access to the object performing the action. let host : Classifier = self.context in let openend : AssociationEnd = self.endData->select(ed | ed.value->size() = 0)->asSequence()->first().end in openend.visibility = #public or self.endData->exists(oed | not oed.end = openend and (host = oed.end.participant or (openend.visibility = #protected and host.allSupertypes->includes(oed.end.participant))))

Parameters:

diagnostics - The chain of diagnostics to which problems are to be appended.

context - The cache of context-specific information.
