Constructor Detail

ExecutionStateChangeEvent

public ExecutionStateChangeEvent(long timestamp,
                         ManagementVertexID managementVertexID,
                         ExecutionState newExecutionState)

Constructs a new vertex event object.

Parameters:

timestamp - the timestamp of the event

managementVertexID - identifies the vertex this event refers to

newExecutionState - the new execution state of the vertex this event refers to

ExecutionStateChangeEvent

public ExecutionStateChangeEvent()

Constructs a new execution state change event object. This constructor is required for the deserialization process and is not supposed to be called directly.

Method Detail

getVertexID

public ManagementVertexID getVertexID()

Returns the ID of the vertex this event refers to.

Returns:

the ID of the vertex this event refers to

getNewExecutionState

public ExecutionState getNewExecutionState()

Returns the new execution state of the vertex this event refers to.

Returns:

the new execution state of the vertex this event refers to
