ITGIS_Shape.IsMapped property

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

Geometry is memory-mapped to a file instead of being fully loaded into memory.

Available also on: Delphi | .NET | Java | Python.

Syntax

// C#
public Boolean IsMapped
{
  get {}
}
' VisualBasic
Public Property IsMapped As Boolean
  Get
  End Get
End Property
// Oxygene
public
  property IsMapped : Boolean read;

Value

Type
bool
Boolean

Remarks

PURPOSE: Query whether the shape geometry is still backed by mapped storage. This helps distinguish low-memory lazy access from fully materialized in-memory geometry.

BEHAVIOR: Returns True when the geometry is read directly from a mapped file buffer and has not yet been copied into the internal shape storage. The value may become False after geometry access or modification forces materialization.

CONSTRAINTS: Read-only. Intended as an implementation state indicator for performance-sensitive vector layer access.
