DK for ActiveX | TatukGIS_XDK11.ITGIS_Shape.Lock | Methods | Properties

Locks the shape for batch geometry updates to defer expensive recalculations.

// C#
public void Lock(
  TGIS_Lock _lock
);

' VisualBasic
Public Sub Lock(
  ByVal _lock As TGIS_Lock
)

// Oxygene
public
  procedure Lock(
    _lock : TGIS_Lock
  );

PURPOSE: Improves performance during bulk editing by postponing extent and related geometry updates until unlocking.

BEHAVIOR: Prevents immediate recalculation of selected cached values while points or parts are being modified. The exact deferred state depends on the _lock mode.

CONSTRAINTS: Must be paired with a later Unlock call to restore normal update behavior.
