Class NameFinderCensus90NameStream

java.lang.Object

opennlp.tools.formats.NameFinderCensus90NameStream

All Implemented Interfaces:

AutoCloseable, ObjectStream<StringList>

public class NameFinderCensus90NameStream
extends Object
implements ObjectStream<StringList>

This class helps to read the US Census data from the files to build a StringList for each dictionary entry in the name-finder dictionary. The entries in the source file are as follows:

SMITH 1.006 1.006 1

• The first field is the name (in ALL CAPS).
• The next field is a frequency in percent.
• The next is a cumulative frequency in percent.
• The last is a ranking.

Note: Do not use this class, internal use only!

This constructor takes an ObjectStream and initializes the class to handle the stream.

Parameters:

lineStream - an ObjectSteam<String> that represents the input file to be attached to this class.

NameFinderCensus90NameStream

public NameFinderCensus90NameStream(InputStreamFactory in,
                                    Charset encoding)
                             throws IOException

Parameters:

in - an InputStreamFactory for the input file.

encoding - the Charset to apply to the input stream.

Throws:

IOException

Method Detail

read

public StringList read()
                throws IOException

Description copied from interface: ObjectStream

Returns the next object. Calling this method repeatedly until it returns null will return each object from the underlying source exactly once.

Specified by:

read in interface ObjectStream<StringList>

Returns:

the next object or null to signal that the stream is exhausted

Throws:

IOException - if there is an error during reading

reset

public void reset()
           throws IOException,
                  UnsupportedOperationException

Description copied from interface: ObjectStream

Repositions the stream at the beginning and the previously seen object sequence will be repeated exactly. This method can be used to re-read the stream if multiple passes over the objects are required. The implementation of this method is optional.

Specified by:

reset in interface ObjectStream<StringList>

Throws:

IOException - if there is an error during reseting the stream

UnsupportedOperationException

close

public void close()
           throws IOException

Description copied from interface: ObjectStream

Closes the ObjectStream and releases all allocated resources. After close was called its not allowed to call read or reset.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface ObjectStream<StringList>

Throws:

IOException - if there is an error during closing the stream
