AGIProcessedDataTerrain

public AGIProcessedDataTerrain(@Nonnull
                               String fileName)

Initializes a new instance using the specified PDTT file.

Parameters:

fileName - The full path and filename of the .PDTT file

Throws:

ArgumentNullException - Thrown when fileName is null.

AGIProcessedDataTerrain

public AGIProcessedDataTerrain(@Nonnull
                               String fileName,

Initializes a new instance using the specified PDTT file and cache group.

Parameters:

fileName - The full path and filename of the .PDTT file

cacheGroup - The cache group with which to associate this terrain provider.

Throws:

ArgumentNullException - Thrown when fileName or cacheGroup is null.

AGIProcessedDataTerrain

public AGIProcessedDataTerrain(@Nonnull
                               StreamFactory streamFactory)

Initializes a new instance using the specified stream factory.

The streams created by streamFactory must support seeking. This means that the streams must implement ISeekableStream or FileInputStream.

Parameters:

streamFactory - The factory to use to create streams to read the terrain data.

Throws:

ArgumentNullException - Thrown when streamFactory is null.

Initializes a new instance using the specified stream factory and cache group.

The streams created by streamFactory must support seeking. This means that the streams must implement ISeekableStream or FileInputStream.

Parameters:

streamFactory - The factory to use to create streams to read the terrain data.

cacheGroup - The cache group with which to associate this terrain provider.

Throws:

ArgumentNullException - Thrown when streamFactory or cacheGroup is null.

Method Detail

getPosts

public TerrainPosts getPosts(@Nonnull
                             RasterTerrainIndexExtent extent)

Returns the altitude values for the input boundary.

Specified by:

getPosts in class RasterTerrainProvider

Parameters:
