Method Detail

isConfigured

boolean isConfigured()

isExecuted

boolean isExecuted()

isDirtyAfterLoad

boolean isDirtyAfterLoad()

Whether this node should be marked as dirty after load. This is true if either the setDirtyAfterLoad() has been set to true or NodeContentPersistor.needsResetAfterLoad() returns true.

Returns:

This property.

setDirtyAfterLoad

void setDirtyAfterLoad()

Sets the dirty flag on this node. The node will also be dirty if the NodeContentPersistor.setNeedsResetAfterLoad() is called.

getModelSettingsFailPolicy

NodePersistor.LoadNodeModelSettingsFailPolicy getModelSettingsFailPolicy()

getSettings

NodeSettingsRO getSettings()
