Message to display when there are connection errors.

构造器详细资料

Activity

public Activity()

Creates activity.

Activity

public Activity(Object userObject)

Creates activity with given userObject. Also creates default port for holding activity transitions.

方法详细资料

getImplementationEditor

public ProcessEditor getImplementationEditor()

getParentEditor

public AbstractEditor getParentEditor()

getPort

public org.jgraph.graph.DefaultPort getPort()

Gets the port associate with this activity.

getConnectionErrorMessage

public String getConnectionErrorMessage()

Returns message that represents connection error for this activity, if there is no connection errors, returns null.
NOTE: You must call method getConnectionErrorMessage() right after calling this isWellConnected() method, otherwise you can get wrong results.

acceptsSource

public boolean acceptsSource()

Returns true if Activity is a valid source for transition. This depends of activitie's type property, it can accept to be a source for transition if it is a normal or starting.

指定者:

acceptsSource 在接口中 Linkable

acceptsTarget

public boolean acceptsTarget()

Returns true if Activity is a valid target for transition. This depends of activitie's type property, it can accept to be a target for for transition if it is a normal or ending.

指定者:

acceptsTarget 在接口中 Linkable

showWebEditor

public void showWebEditor(Window parentWindow,
                          AbstractGraph graph)

Shows a dialog for editing activity properties.

showPropertyDialog

public void showPropertyDialog(Window parentWindow,
                               AbstractGraph graph)

Shows a dialog for editing activity properties.

指定者:

showPropertyDialog 在接口中 WorkflowElement

getPropertyObject

public XMLElement getPropertyObject()

Gets a property object (DTDElement).

指定者:

getPropertyObject 在接口中 WorkflowElement

get

public XMLElement get(String what)

Gets an activity property which name is given in parameter what.

指定者:

get 在接口中 WorkflowElement

set

public void set(String what,
                Object value)

Sets value of an activity property which name is given in parameter what to a value given in a parameter value.

指定者:

set 在接口中 WorkflowElement

getTooltip

public String getTooltip()

Gets a tooltip text for activity.

指定者:

getTooltip 在接口中 WorkflowElement

toString

public String toString()

Gets an activity "display name" property.

覆盖:

toString 在类中 DefaultMutableTreeNode

clone

public Object clone()

Create a clone of the cell. The cloning of the user object is deferred to the cloneUserObject() method. NOTE: this original method of DefaultGraphCell is modified to retain synchronization of userObject and value attribute from attribute map when model is attribute store

覆盖:

clone 在类中 org.jgraph.graph.DefaultGraphCell

返回:

Object a clone of this object.

cloneUserObject

protected Object cloneUserObject()

Create a clone of the ActivityProperties object.

覆盖:

cloneUserObject 在类中 org.jgraph.graph.DefaultGraphCell

返回:

Object a clone of this activity property object.

hasAnyPrecondition
