Class SuffixSensitiveGISModelReader

java.lang.Object
  opennlp.maxent.io.GISModelReader
      opennlp.maxent.io.SuffixSensitiveGISModelReader

Direct Known Subclasses:

PooledGISModelReader

public class SuffixSensitiveGISModelReader
extends GISModelReader

A reader for GIS models which inspects the filename and invokes the appropriate GISModelReader depending on the filename's suffixes.

The following assumption are made about suffixes:

.gz --> the file is gzipped (must be the last suffix)

.txt --> the file is plain text

.bin --> the file is binary

Constructor Detail

SuffixSensitiveGISModelReader

public SuffixSensitiveGISModelReader(java.io.File f)
                              throws java.io.IOException

Constructor which takes a File and invokes the GISModelReader appropriate for the suffix.

Parameters:

f - The File in which the model is stored.

Throws:

java.io.IOException

Method Detail

readInt

protected int readInt()
               throws java.io.IOException

Description copied from class: GISModelReader

Implement as needed for the format the model is stored in.

Specified by:

readInt in class GISModelReader

Throws:

java.io.IOException

readDouble

protected double readDouble()
                     throws java.io.IOException

Description copied from class: GISModelReader

Implement as needed for the format the model is stored in.

Specified by:

readDouble in class GISModelReader

Throws:

java.io.IOException

readUTF

protected java.lang.String readUTF()
                            throws java.io.IOException

Description copied from class: GISModelReader

Implement as needed for the format the model is stored in.

Specified by:

readUTF in class GISModelReader

Throws:

java.io.IOException

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException

To convert between different formats of the new style.

java opennlp.maxent.io.SuffixSensitiveGISModelReader old_model_name new_model_name

For example, to convert a model called "model.bin.gz" (which is thus saved in gzipped binary format) to one in (unzipped) text format:

java opennlp.maxent.io.SuffixSensitiveGISModelReader model.bin.gz model.txt

This particular example would of course be useful when you generally want to create models which take up less space (.bin.gz), but want to be able to inspect a few of them as plain text files.

Throws:

java.io.IOException
