public ExecutionVertexID()

Method Detail

toManagementVertexID

public ManagementVertexID toManagementVertexID()

Converts the execution vertex ID into a management vertex ID. The new management vertex ID will be equal to the execution vertex ID in the sense that the equals method will return true when both IDs are compared.

Returns:

the new management vertex ID

fromManagementVertexID

public static ExecutionVertexID fromManagementVertexID(ManagementVertexID vertexID)

Converts the given management vertex ID into the corresponding execution vertex ID. The new execution vertex ID will be equals to the management vertex ID in the sense that the equals method will return true when both IDs are compared.

Parameters:

vertexID - the management vertex ID to be converted

Returns:

the resulting execution vertex ID
