• GetDiskUsed

  public int GetDiskUsed​(StreamVersion rkVersion)

  Returns the size of this object and it's children on disk for the current StreamVersion parameter.

  Specified by:

  GetDiskUsed in interface StreamInterface

  Overrides:

  GetDiskUsed in class Geometry

  Parameters:

  rkVersion - the current version of the Stream file being created.

  Returns:

  the size of this object on disk.

• Link

  public void Link​(Stream rkStream,
                   Stream.Link pkLink)

  Copies this objects children objects from the input Stream's HashTable, based on the LinkID of the child stored in the pkLink parameter.

  Specified by:

  Link in interface StreamInterface

  Overrides:

  Link in class Geometry

  Parameters:

  rkStream - the Stream where the child objects are stored.

  pkLink - the Link class from which the child object IDs are read.

• Load

  public void Load​(Stream rkStream,
                   Stream.Link pkLink)

  Loads this object from the input parameter rkStream, using the input Stream.Link to store the IDs of children objects of this object for linking after all objects are loaded from the Stream.

  Specified by:

  Load in interface StreamInterface

  Overrides:

  Load in class Geometry

  Parameters:

  rkStream - the Stream from which this object is being read.

  pkLink - the Link class for storing the IDs of this object's children objects.

• Register

  public boolean Register​(Stream rkStream)

  Registers this object with the input Stream parameter. All objects streamed to disk are registered with the Stream so that a unique list of objects is maintained.

  Specified by:

  Register in interface StreamInterface

  Overrides:

  Register in class Geometry

  Parameters:

  rkStream - the Stream where the child objects are stored.

  Returns:

  true if this object is registered, false if the object has already been registered.

  Write this object and all it's children to the Stream.

  Specified by:

  Save in interface StreamInterface

  Overrides:

  Save in class Geometry

  Parameters:

  rkStream - the Stream where the child objects are stored.

  Specified by:

  SaveStrings in interface StreamInterface

  Overrides:

  SaveStrings in class Geometry

  Parameters:

  acTitle - the header for this object in the StringTree.

  Returns:

  StringTree containing a String-based representation of this object and it's children.

• SetActiveQuantity

  public void SetActiveQuantity​(int iActiveQuantity)

  Set closed value.

  Parameters:

  bClosed - polyline closed value.

• SetContiguous

  public void SetContiguous​(boolean bContiguous)

  Set contiguous value.

  Parameters:

• SetGeometryType

  protected void SetGeometryType​(boolean bInit)

  Sets the geometric type based on the closed and contiguous values.

  Parameters:

  bInit - when true the function is called from the Constructor, so do not increment/decrement index quantity.
