setJavaScriptObject

public void setJavaScriptObject(com.google.gwt.core.client.JavaScriptObject jsObj)

Overrides:

setJavaScriptObject in class BaseClass

create

public com.google.gwt.core.client.JavaScriptObject create()

Specified by:

create in class BaseClass

isCreated

public boolean isCreated()

Overrides:

isCreated in class BaseClass

getOrCreateJsObj

public com.google.gwt.core.client.JavaScriptObject getOrCreateJsObj()

Overrides:

getOrCreateJsObj in class BaseClass

setClassDescription

public void setClassDescription(java.lang.String classDescription)
                         throws java.lang.IllegalStateException

Optional description of the general nature of the kinds of tasks this this process element performs. Not to be confused with description which describes what the specific instance of the process element has been configured to do.

For example, the classDescription for a task to disable a field might be "disables a field" whereas the description for a concrete instance might be "disables the 'shipTo' field in the 'ordering' form".

Used by editor to display additional details along with title.

Parameters:

classDescription - New classDescription value. Default value is null

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getClassDescription

public java.lang.String getClassDescription()

Optional description of the general nature of the kinds of tasks this this process element performs. Not to be confused with description which describes what the specific instance of the process element has been configured to do.

For example, the classDescription for a task to disable a field might be "disables a field" whereas the description for a concrete instance might be "disables the 'shipTo' field in the 'ordering' form".

Used by editor to display additional details along with title.

Returns:

Current classDescription value. Default value is null

setDescription

public void setDescription(java.lang.String description)
                    throws java.lang.IllegalStateException

Optional description for this specific instance of process element.

Parameters:

description - New description value. Default value is null

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getDescription

public java.lang.String getDescription()

Optional description for this specific instance of process element.

Returns:

Current description value. Default value is null

setEditorType

public void setEditorType(java.lang.String editorType)
                   throws java.lang.IllegalStateException

Editor type used to edit instances of this type of process element.

Parameters:

editorType - New editorType value. Default value is null

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getEditorType

public java.lang.String getEditorType()

Editor type used to edit instances of this type of process element.

Returns:

Current editorType value. Default value is null

setID

public void setID(java.lang.String ID)
           throws java.lang.IllegalStateException

Optional ID for this process element, allowing it to be referred to from Gateways, or as the Process.startElement. See ProcessSequence and Process to understand when this is required or can be omitted.

Unlike Canvas.ID a processElement's is a not a globally unique variable, it need only by unique within it's process.

When assigned an ID, a processElement can be retrieve via Process.getElement().

Overrides:

setID in class BaseClass

Parameters:

ID - New ID value. Default value is null

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getID

public java.lang.String getID()

Optional ID for this process element, allowing it to be referred to from Gateways, or as the Process.startElement. See ProcessSequence and Process to understand when this is required or can be omitted.

Unlike Canvas.ID a processElement's is a not a globally unique variable, it need only by unique within it's process.

When assigned an ID, a processElement can be retrieve via Process.getElement().

Overrides:

getID in class BaseClass

Returns:

Current ID value. Default value is null

setNextElement

public void setNextElement(java.lang.String nextElement)
                    throws java.lang.IllegalStateException

Next sequence or element to execute after this one completes.

nextElement does not need to be specified on most elements if you use sequences.

Note that if there is both a sequence and a normal element with the same name in the current Process, the sequence will be used.

Parameters:

nextElement - New nextElement value. Default value is null

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getNextElement

public java.lang.String getNextElement()

Next sequence or element to execute after this one completes.

nextElement does not need to be specified on most elements if you use sequences.

Note that if there is both a sequence and a normal element with the same name in the current Process, the sequence will be used.

Returns:

Current nextElement value. Default value is null

setPassThruOutput
