org.eclipse.uml2.uml
Interface ExceptionHandler

All Superinterfaces:
Element, org.eclipse.emf.ecore.EModelElement, org.eclipse.emf.ecore.EObject, org.eclipse.emf.common.notify.Notifier

public interface ExceptionHandler
extends Element

A representation of the model object ' Exception Handler '. An exception handler is an element that specifies a body to execute in case the specified exception occurs during the execution of the protected node.

The following features are supported:

Method Detail

getHandlerBody

ExecutableNode getHandlerBody()
Returns the value of the ' Handler Body ' reference. A node that is executed if the handler satisfies an uncaught exception.

Returns:
the value of the 'Handler Body' reference.
See Also:
setHandlerBody(ExecutableNode), UMLPackage.getExceptionHandler_HandlerBody()

setHandlerBody

void setHandlerBody(
ExecutableNode value)
Sets the value of the ' Handler Body' reference.

Parameters:
value - the new value of the 'Handler Body' reference.
See Also:
getHandlerBody()

getExceptionInput

ObjectNode getExceptionInput()
Returns the value of the ' Exception Input ' reference. An object node within the handler body. When the handler catches an exception, the exception token is placed in this node, causing the body to execute.

Returns:
the value of the 'Exception Input' reference.
See Also:
setExceptionInput(ObjectNode), UMLPackage.getExceptionHandler_ExceptionInput()

setExceptionInput

void setExceptionInput(
ObjectNode value)
Sets the value of the ' Exception Input' reference.

Parameters:
value - the new value of the 'Exception Input' reference.
See Also:
getExceptionInput()

getExceptionTypes

org.eclipse.emf.common.util.EList<
Classifier> getExceptionTypes()
Returns the value of the ' Exception Type ' reference list. The list contents are of type Classifier. The kind of instances that the handler catches. If an exception occurs whose type is any of the classifiers in the set, the handler catches the exception and executes its body.

Returns:
the value of the 'Exception Type' reference list.
See Also:
UMLPackage.getExceptionHandler_ExceptionType()

getExceptionType

Classifier getExceptionType(java.lang.String name)
Retrieves the first Classifier with the specified ' Name ' from the ' Exception Type ' reference list.

Parameters:
name - The ' Name ' of the Classifier to retrieve, or null.
Returns:
The first Classifier with the specified ' Name ', or null.
See Also:
getExceptionTypes()

getExceptionType

Classifier getExceptionType(java.lang.String name,
                            boolean ignoreCase,
                            org.eclipse.emf.ecore.EClass eClass)
Retrieves the first Classifier with the specified ' Name ' from the ' Exception Type ' reference list.

Parameters:
name - The ' Name ' of the Classifier to retrieve, or null.
ignoreCase - Whether to ignore case in String comparisons.
eClass - The Ecore class of the Classifier to retrieve, or null.
Returns:
The first Classifier with the specified ' Name ', or null.
See Also:
getExceptionTypes()

getProtectedNode

ExecutableNode getProtectedNode()
Returns the value of the ' Protected Node ' container reference. It is bidirectional and its opposite is ' Handler'.

This feature subsets the following features:

The node protected by the handler. The handler is examined if an exception propagates to the outside of the node.

Returns:
the value of the 'Protected Node' container reference.
See Also:
setProtectedNode(ExecutableNode), UMLPackage.getExceptionHandler_ProtectedNode(), ExecutableNode.getHandlers()

setProtectedNode

void setProtectedNode(
ExecutableNode value)
Sets the value of the ' Protected Node' container reference.

Parameters:
value - the new value of the 'Protected Node' container reference.
See Also:
getProtectedNode()

validateExceptionBody

boolean validateExceptionBody(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                              java.util.Map<java.lang.Object,java.lang.Object> context)
The exception handler and its input object node are not the source or target of any edge. true

Parameters:
diagnostics - The chain of diagnostics to which problems are to be appended.
context - The cache of context-specific information.

validateResultPins

boolean validateResultPins(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                           java.util.Map<java.lang.Object,java.lang.Object> context)
The result pins of the exception handler body must correspond in number and types to the result pins of the protected node. true

Parameters:
diagnostics - The chain of diagnostics to which problems are to be appended.
context - The cache of context-specific information.

validateOneInput

boolean validateOneInput(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                         java.util.Map<java.lang.Object,java.lang.Object> context)
The handler body has one input, and that input is the same as the exception input. true

Parameters:
diagnostics - The chain of diagnostics to which problems are to be appended.
context - The cache of context-specific information.

validateEdgeSourceTarget

boolean validateEdgeSourceTarget(org.eclipse.emf.common.util.DiagnosticChain diagnostics,
                                 java.util.Map<java.lang.Object,java.lang.Object> context)
An edge that has a source in an exception handler structured node must have its target in the handler also, and vice versa. true

Parameters:
diagnostics - The chain of diagnostics to which problems are to be appended.
context - The cache of context-specific information.
