@Internal
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!

NameFinderCensus90NameStream

public NameFinderCensus90NameStream(ObjectStream<String> lineStream)

Initializes a NameFinderCensus90NameStream via ObjectStream<String>.

Parameter:

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

NameFinderCensus90NameStream

public NameFinderCensus90NameStream(InputStreamFactory in,
 Charset encoding)
                             throws IOException

Initializes a NameFinderCensus90NameStream via an InputStreamFactory and a Charset. Opens an associated stream object with the specified encoding specified.

Parameter:

in - The InputStreamFactory for the input file.

encoding - the Charset to apply to the input stream.

Löst aus:

IOException - Thrown if IO errors occurred.

Methodendetails

read

public StringList read()
                throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

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

Angegeben von:

read in Schnittstelle ObjectStream<StringList>

Gibt zurück:

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

Löst aus:

IOException - Thrown if there is an error during reading.

reset

public void reset()
           throws IOException,
UnsupportedOperationException

Beschreibung aus Schnittstelle kopiert: 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.

Angegeben von:

reset in Schnittstelle ObjectStream<StringList>

Löst aus:

IOException - Thrown if there is an error during resetting the stream.

UnsupportedOperationException - Thrown if the reset() is not supported. By default, this is the case.

close

public void close()
           throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Closes the ObjectStream and releases all allocated resources. After close was called, it's not allowed to call ObjectStream.read() or ObjectStream.reset().

Angegeben von:

close in Schnittstelle AutoCloseable

Angegeben von:

close in Schnittstelle ObjectStream<StringList>

Löst aus:

IOException - Thrown if there is an error during closing the stream.
