                             long ptr,
                             java.io.OutputStream os)

Writes the spatial index for a polygon shape file.

Parameters:

is - the shape file input stream

ptr - the current position in the file

os - the spatial index file output stream

indexPoints

protected void indexPoints(java.io.InputStream is,
                           long ptr,
                           java.io.OutputStream os)

Writes the spatial index for a point shape file.

Parameters:

is - the shape file input stream

ptr - the current position in the file

os - the spatial index file output stream

indexNulls

protected void indexNulls(java.io.InputStream is,
                          long ptr,
                          java.io.OutputStream os)

Writes the spatial index for a null shape file.

Parameters:

is - the shape file input stream

ptr - the current position in the file

os - the spatial index file output stream

createIndex

public void createIndex(java.lang.String inFile)

Creates a spatial index for a shape file. Reads the records from the shape file, writing appropriate index records to the spatial index file.

Parameters:

inFile - the shape file or spatial index file, the method will figure it out based on the file name extension.
