Method Detail

isSwitchFor

protected boolean isSwitchFor(EPackage ePackage)

Checks whether this is a switch for the given package.

Parameters:

ePackage - the package in question.

Returns:

whether this is a switch for the given package.

doSwitch

protected T doSwitch(int classifierID,
                     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.

caseQuery

public T caseQuery(Query object)

Returns the result of interpreting the object as an instance of '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 'Query'.

doSwitch(EObject)

caseQueryCondition

public T caseQueryCondition(QueryCondition object)

Returns the result of interpreting the object as an instance of 'Condition'. 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 'Condition'.

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'.
