Constructor Detail

NodeInstanceImpl

public NodeInstanceImpl()

Method Detail

setId

public void setId(long id)

getId

public long getId()

Description copied from interface: NodeInstance

The id of the node instance. This is unique within the node instance container this node instance lives in.

Specified by:

getId in interface NodeInstance

Returns:

the id of the node instance

setNodeId

public void setNodeId(long nodeId)

getNodeId

public long getNodeId()

Description copied from interface: NodeInstance

The id of the node this node instance refers to. The node represents the definition that this node instance was based on.

Specified by:

getNodeId in interface NodeInstance

Returns:

the id of the node this node instance refers to

getNodeName

public String getNodeName()

Description copied from interface: NodeInstance

The name of the node this node instance refers to.

Specified by:

getNodeName in interface NodeInstance

Returns:

the name of the node this node instance refers to

setProcessInstance

public void setProcessInstance(WorkflowProcessInstance processInstance)

getProcessInstance

public WorkflowProcessInstance getProcessInstance()

Description copied from interface: NodeInstance

The process instance that this node instance is executing in.

Specified by:

getProcessInstance in interface NodeInstance

Returns:

the process instance that this node instance is executing in

getNodeInstanceContainer

public NodeInstanceContainer getNodeInstanceContainer()

Description copied from interface: NodeInstance

The node instance container that this node instance is part of. If the node was defined in the top-level process scope, this is the same as the process instance. If not, it is the node instance container this node instance is executing in.

Specified by:

getNodeInstanceContainer in interface NodeInstance

Returns:

the process instance that this node instance is executing in

setNodeInstanceContainer

public void setNodeInstanceContainer(NodeInstanceContainer nodeInstanceContainer)

getNode

public Node getNode()

Description copied from interface: NodeInstance

Return the node this node instance refers to. The node represents the definition that this node instance was based on.

Specified by:

getNode in interface NodeInstance

Returns:

the node this node instance refers to

isInversionOfControl

public boolean isInversionOfControl()

cancel

public void cancel()

trigger

public final void trigger(NodeInstance from,
