Constructor Detail

LinkSpatialIndex

public LinkSpatialIndex(java.lang.String ssxFilename)
                 throws java.io.IOException

Opens a spatial index file for reading.

Parameters:

ssxFilename - the name of the spatial index file

Throws:

java.io.IOException - if something goes wrong opening the file

LinkSpatialIndex

public LinkSpatialIndex(java.lang.String ssxFilename,
                        java.lang.String shpFilename)
                 throws java.io.IOException

Opens a spatial index file and it's associated shape file.

Parameters:

ssxFilename - the name of the spatial index file

shpFilename - the name of the shape file

Throws:

java.io.IOException - if something goes wrong opening the files

Method Detail

makeESRIRecord

public ESRIRecord makeESRIRecord(int shapeType,
                                 byte[] b,
                                 int off)
                          throws java.io.IOException

Creates a record instance from the shape file data. Calls the appropriate record constructor based on the shapeType, and passes the buffer and offset to that constructor.

Overrides:

makeESRIRecord in class SpatialIndex

Parameters:

shapeType - the shape file's shape type, enumerated in ShapeUtils

b - the buffer pointing to the raw record data

off - the offset of the data starting point in the buffer

Throws:

java.io.IOException - if something goes wrong reading the file
