Parameters:

ppReturns - A reference to a com.esri.arcgis.system.ILongArray (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getReturns

ILongArray getReturns()
                      throws IOException,
                             AutomationException

The return numbers.

Description

Returns is a LongArray containing the lidar return numbers of interest. Any point with a return equal to one of the values in the passed array is considered for inclusion by the filter. The valid return number range is 1-5.

Parameters:

ppCodes - A reference to a com.esri.arcgis.system.ILongArray (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getClassCodes

ILongArray getClassCodes()
                         throws IOException,
                                AutomationException

The classification codes.

Description

ClassCodes is a LongArray containing the LAS classification codes of interest. Any point with a code equal to one of the values in the passed array is considered for inclusion by the filter. The valid LAS class code range is 0-31 for Las file versions 1.1, 1.2, 1.3 and 0-255 for version 1.0.

Returns:

A reference to a com.esri.arcgis.system.ILongArray

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setClassFlags

void setClassFlags(int pFlags)
                   throws IOException,
                          AutomationException

The classification flags.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

pFlags - The pFlags (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getClassFlags

int getClassFlags()
                  throws IOException,
                         AutomationException

The classification flags.

Description

ClassFlags is used to specify which points, based on their LAS classification flag settings, are considered for inclusion by the filter. The LAS specification supports three class flag types: synthetic, key-point, and witheld. The value can be set equal to one of the constants defined in the esriLasClassFlag enumeration. You can also set the value to the result of a bitwise operation performed on these same constants in order to use them in combination.

Returns:

The pFlags

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
