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)

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

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)

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