Class AbstractCriticalTransferHandler

java.lang.Object

javax.swing.TransferHandler

megameklab.ui.util.AbstractCriticalTransferHandler

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

BAASCriticalTransferHandler, BMCriticalTransferHandler, CriticalTransferHandler

public class AbstractCriticalTransferHandler
extends TransferHandler

This is a base class for some of the transfer handlers used in MML. There is a conflict of targets between unifying them and keeping them readable because of the different handling the different Entity types require.

getSourceActions

public int getSourceActions(JComponent c)

Overrides:

changeMountStatus

protected void changeMountStatus(megamek.common.equipment.Mounted<?> eq,
 int location)

Moves the given equipment to the given location (removing it from any former location). Forwards to UnitUtil .changeMountStatus() and calls for a refresh using the present refresh listener, if any.

Parameters:

eq - The Mounted to move

location - The new location; may be LOC_NONE

See Also:

• UnitUtil.changeMountStatus(Entity, Mounted, int, int, boolean)

changeMountStatus

protected void changeMountStatus(megamek.common.equipment.Mounted<?> eq,
 int location,
 int secondaryLocation)

Moves the given equipment to the given location (removing it from any former location) and secondary location. Forwards to UnitUtil.changeMountStatus() and calls for a refresh using the present refresh listener, if any.

Parameters:

eq - The Mounted to move

location - The new location; may be LOC_NONE

secondaryLocation - The new secondary location

See Also:

• UnitUtil.changeMountStatus(Entity, Mounted, int, int, boolean)

getUnit

protected megamek.common.units.Entity getUnit()

Returns:

The unit that is currently edited.

setRefresh

public void setRefresh(RefreshListener refresh)

Sets a refresh listener to forward refresh calls to. Calls to doRefresh() will use it.

Parameters:

refresh - The new refresh listener

doRefresh

protected void doRefresh()

Calls for a refresh using the present refresh listener, if any. If no refresh listener has been set, does nothing.

getMountedFromTransferable

protected megamek.common.equipment.Mounted<?> getMountedFromTransferable(Transferable transferable)

Gets the Mounted equipment from the given transferable. All exceptions are caught and null is returned instead if an exception occurred. This implicitly checks if the String data flavor is supported.

Parameters:

transferable - The Transferable from the present transfer action

Returns:

The equipment that is being dragged or null in the case of any error

isDraggable

protected boolean isDraggable(@Nullable
 megamek.common.equipment.Mounted<?> mounted)

Returns true when the given mounted is allowed to be dragged on the present unit type, false otherwise. Returns false when the given mounted is null.

Parameters:

mounted - The Mounted equipment

Returns:

True when dragging is allowed, false otherwise

doImport

protected boolean doImport(megamek.common.equipment.Mounted<?> mounted,
 Component target)
