Specified by:

getParameterName in interface ParameterNode

Returns:

the name of the parameter that this node is inputting/outputting

setParameterName

public void setParameterName(java.lang.String name)

Sets the parameter that this node is inputting/outputting

Specified by:

setParameterName in interface ParameterNode

isDataNode

public boolean isDataNode()

Specified by:

isDataNode in interface Node

Overrides:

isDataNode in class NodeImp

Returns:

true if this node is a data node

isParameterNode

public boolean isParameterNode()

Specified by:

isParameterNode in interface Node

Overrides:

isParameterNode in class NodeImp

Returns:

true if this node is a parameter node

isTriggerNode

public boolean isTriggerNode()

Specified by:

isTriggerNode in interface ParameterNode

Returns:

true if this parameter node is a trigger node

setTriggerNode

public void setTriggerNode(boolean state)

Sets this parameter node as a trigger node, If true then the node is essential for the task to run, otherwise it is optional.

Specified by:

setTriggerNode in interface ParameterNode

isErrorNode

public boolean isErrorNode()

Specified by:

isErrorNode in interface ParameterNode

Returns:

true if this parameter node is a error node

setErrorNode

public void setErrorNode(boolean state)

Sets this parameter node as a error node, If true then the node is essential for the task to run, otherwise it is optional.

Specified by:

setErrorNode in interface ParameterNode

isEssential

public boolean isEssential()

Specified by:

isEssential in interface Node

Overrides:

isEssential in class NodeImp

Returns:

true if data is essential at this node for the task to run. Note that data nodes are essential by default.

isEssentialIfConnected

public boolean isEssentialIfConnected()

Specified by:

isEssentialIfConnected in interface Node

Overrides:

isEssentialIfConnected in class NodeImp

Returns:

true if data is essential at this node only if the node is connected

isOptional

public boolean isOptional()

Specified by:

isOptional in interface Node

Overrides:

isOptional in class NodeImp

Returns:

true if data is not required at this node for the task to run. Note that parameter nodes are optional by default.
