Detailed Description

Data structure holding a vector of data points. To reduce footprint, the data is sent as 8 bit values (octet). The data-structure holds an offset and a scaling factor, to restore the original data samples. e.g. double value = data * scale + offset The density parameter allows a layer to be of lower resolution than the map itself. Map layer data for data samples reduced to 16 bit values. Data structure holding a vector of data points. To reduce footprint, the data is sent as 16 bit values (short). The data-structure holds an offset and a scaling factor, to restore the original data samples. e.g. double value = data * scale + offset The density parameter allows a layer to be of lower resolution than the map itself.

Member Function Documentation

Object copy_from

(

Object

src

)

This method will perform a deep copy of src This method could be placed into ShortMapLayerTypeSupport rather than here by using the -noCopyable option to rtiddsgen.

Parameters:

src	The Object which contains the data to be copied.

Returns:

Returns this.

Exceptions:

NullPointerException	If src is null.
ClassCastException	If src is not the same type as this.
