Method Detail

init

public void init()

Initialization

Overrides:

init in class PjWorkshop

reset

public void reset()

Reset workshop and geometry to original state.

Overrides:

reset in class PjWorkshop

close

public void close()

Close workshop and remove workshop from geometry as update listener. Instance variables of this workshop are nulled.

Overrides:

close in class PjWorkshop

setGeometry

public void setGeometry(PgElementSet geom)

Assign geometry to be analyzed.

Parameters:

geom - geometry for analysis

update

public boolean update(java.lang.Object event)

Description copied from class: PjWorkshop

Updates the geometry if this workshop has changed, i.e. if the event is this or null. Also propagates update() to superclass with the original argument event.

Some subclasses may register themselves as update listener of the geometry of this workshop. In order to prevent an update loop, this method safely uses isUpdateSender() when updating the geometry.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PjWorkshop

Parameters:

event - sender of this update.

Returns:

true if update was correctly handled by superclass.

PsObject.setParent(PsUpdateIf), PsObject.getFather(), PsObject.addUpdateListener(PsUpdateIf)

getItemType

public int getItemType()

Get the item type which determines the displayed data. Possible types are like PwHistogram#ITEM_EDGE_LENGTH etc.

Returns:

the current item type

setItemType

public void setItemType(int itemType)

Set the item type which determines the displayed data. Possible types are like PwHistogram#ITEM_EDGE_LENGTH etc.

Parameters:

itemType - the new item type
