Class GISModelWriter

java.lang.Object
  opennlp.maxent.io.GISModelWriter

Direct Known Subclasses:

BinaryGISModelWriter, ObjectGISModelWriter, PlainTextGISModelWriter, SuffixSensitiveGISModelWriter

public abstract class GISModelWriter
extends java.lang.Object

Abstract parent class for GISModel writers. It provides the persist method which takes care of the structure of a stored document, and requires an extending class to define precisely how the data should be stored.

Method Detail

writeUTF

protected abstract void writeUTF(java.lang.String s)
                          throws java.io.IOException

Throws:

java.io.IOException

writeInt

protected abstract void writeInt(int i)
                          throws java.io.IOException

Throws:

java.io.IOException

writeDouble

protected abstract void writeDouble(double d)
                             throws java.io.IOException

Throws:

java.io.IOException

close

protected abstract void close()
                       throws java.io.IOException

Throws:

java.io.IOException

persist

public void persist()
             throws java.io.IOException

Writes the model to disk, using the writeX() methods provided by extending classes.

If you wish to create a GISModelWriter which uses a different structure, it will be necessary to override the persist method in addition to implementing the writeX() methods.

Throws:

java.io.IOException

sortValues

protected ComparablePredicate[] sortValues()

compressOutcomes

protected java.util.List compressOutcomes(ComparablePredicate[] sorted)
