Enumeration PartInstanceMatrixGetterInterfaceSignal

The PartInstanceMatrixGetterInterfaceSignal lists all the signals that may be sent by the PartInstanceMatrixGetterInterface.

These signals are emitted by the PartInstanceMatrixGetterInterface when a part instance matrix fetch result is ready.

• MatrixFetchReady : the PartInstanceMatrixGetterInterface is ready, i.e. when it has finished a matrix fetch, PartInstanceMatrixGetterInterface.getMatricesResult can be called.
• MatrixFetchCancelled : the fetch request by the PartInstanceMatrixGetterInterface has been cancelled.
