  extended by org.eclipse.gmt.modisco.infra.query.util.QuerySwitch<T>

public class QuerySwitch<T>
extends java.lang.Object

The Switch for the model's inheritance hierarchy. It supports the call doSwitch(object) to invoke the caseXXX method for each class of the model, starting with the actual class of the object and proceeding up the inheritance hierarchy until a non-null result is returned, which is the result of the switch.

QuerySwitch

public QuerySwitch()
Creates an instance of the switch.

Method Detail

doSwitch

public T doSwitch(EObject theEObject)
Calls caseXXX for each class of the model until one returns a non null result; it yields that result.

Returns:
the first non-null result returned by a caseXXX call.

caseModelQuerySet

public T caseModelQuerySet(ModelQuerySet object)
Returns the result of interpreting the object as an instance of 'Model Query Set'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:
object - the target of the switch.
Returns:
the result of interpreting the object as an instance of 'Model Query Set'.
See Also:
doSwitch(EObject)

caseModelQuery

public T caseModelQuery(ModelQuery object)
Returns the result of interpreting the object as an instance of 'Model Query'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:
object - the target of the switch.
Returns:
the result of interpreting the object as an instance of 'Model Query'.
See Also:
doSwitch(EObject)

caseJavaModelQuery

public T caseJavaModelQuery(JavaModelQuery object)
Returns the result of interpreting the object as an instance of 'Java Model Query'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:
object - the target of the switch.
Returns:
the result of interpreting the object as an instance of 'Java Model Query'.
See Also:
doSwitch(EObject)

caseModelQueryParameter

public T caseModelQueryParameter(ModelQueryParameter object)
Returns the result of interpreting the object as an instance of 'Model Query Parameter'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:
object - the target of the switch.
Returns:
the result of interpreting the object as an instance of 'Model Query Parameter'.
See Also:
doSwitch(EObject)

caseOCLModelQuery

public T caseOCLModelQuery(OCLModelQuery object)
Returns the result of interpreting the object as an instance of 'OCL Model Query'. This implementation returns null; returning a non-null result will terminate the switch.

Parameters:
object - the target of the switch.
Returns:
the result of interpreting the object as an instance of 'OCL Model Query'.
See Also:
doSwitch(EObject)

defaultCase

public T defaultCase(EObject object)
Returns the result of interpreting the object as an instance of 'EObject'. This implementation returns null; returning a non-null result will terminate the switch, but this is the last case anyway.

Parameters:
object - the target of the switch.
Returns:
the result of interpreting the object as an instance of 'EObject'.
