void setAttribute(int pAttribute)
throws IOException,
AutomationException
pAttribute - A com.esri.arcgis.geodatabaseextensions.esriLasAttributeType constant (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
int getAttribute()
throws IOException,
AutomationException
Attribute is relevant when working with methods NextAttrDbl and NextAttrLong. Set this property before invoking those methods. If this property is not set, it defaults to esriLasAttributeType.esriLasClassCode.
All values except esriLasAttributeType.esriLasColorRGB is a valid input while setting this property.
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
void reset()
throws IOException,
AutomationException
Resets the enumerator
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
void next(int arraySize,
int[] pPointCount,
_WKSPointZ[] pPoints,
ILongArray pIntensity,
ILongArray pFileIndices,
IDoubleArray pPointIDs)
throws IOException,
AutomationException
Retrieves points from a LAS dataset. Intended to be called in a loop.
arraySize is the allocated size of the array into which points will be retrieved. This tells the enumerator how many points it can retrieve for each call to Next.
pPointCount is a result, set by the call to Next, and represents the number of points retrieved into the point array. The value will be <= arraySize. When it's 0 there are no more points to retrieve.
pPoints is an array of WKSPointZ. Points are retrieved into it. It must be pre-allocated. It's size must be at least as large as arraySize.
pIntensity is an array into which lidar intensity values are placed for the retrieved points. The LongArray object needs to be instantiated if you want to retrieve intensity. Pre-existing values in the array, if any, will be cleared before new values are loaded. Pass NULL for this parameter if you don't need intensity values.
pFileIndices is an array into which las file index (i.e., ILasDataset.File) values are placed for the retrieved points. This enables you top determine which LAS file each point comes from. The indices start at a base of 0. The passed LongArray object needs to be instantiated if you want to retrieve this information. Pre-existing values in the array, if any, will be cleared before new values are loaded. Pass NULL for this parameter if you don't need the file indices.
pPointIDs is an array into which record numbers for retrieved points are placed. These are LAS file point record numbers and they start at a base of 1. These, used in combination with the file indices, enable you to uniquely identify the source of each point; the LAS file and the record number in that file. The DoubleArray object needs to be instantiated if you want to retrieve this information. Pre-existing values in the array, if any, will be cleared before new values are loaded. Pass NULL for this parameter if you don't need point record numbers.
This method uses C style arrays which are not supported in the ArcGIS API for Java. Hence the array size cannot be greater than 1. You can only retrieve information for one point at a time.

throws IOException,

Retrieves points and desired attributes as long values from a LAS dataset. Intended to be called in a loop.
Double attribute values such as esriLasAttributeType.esriLasZ and esriLasAttributeType.esriLasGpsTime will be rounded off.
arraySize is the allocated size of the array into which points will be retrieved. This tells the enumerator how many points it can retrieve for each call to Next.
pPointCount is a result, set by the call to Next, and represents the number of points retrieved into the point array. The value will be <= arraySize. When it's 0 there are no more points to retrieve.
pPoints is an array of WKSPointZ. Points are retrieved into it. It must be pre-allocated. It's size must be at least as large as arraySize.
pAttribute is an array of the specified attributes as long values.
pIntensity is an array into which lidar intensity values are placed for the retrieved points. The LongArray object needs to be instantiated if you want to retrieve intensity. Pre-existing values in the array, if any, will be cleared before new values are loaded. Pass NULL for this parameter if you don't need intensity values.
pFileIndices is an array into which las file index (i.e., ILasDataset.File) values are placed for the retrieved points. This enables you top determine which LAS file each point comes from. The indices start at a base of 0. The passed LongArray object needs to be instantiated if you want to retrieve this information.
