Constructor Detail

ADPOSSampleStream

public ADPOSSampleStream(ObjectStream<String> lineStream,
                         boolean expandME,
                         boolean includeFeatures)
Creates a new POSSample stream from a line stream, i.e. ObjectStream< String>, that could be a PlainTextByLineStream object.

Parameters:
lineStream - a stream of lines as String
expandME - if true will expand the multiword expressions, each word of the expression will have the POS Tag that was attributed to the expression plus the prefix B- or I- (CONLL convention)
includeFeatures - if true will combine the POS Tag with the feature tags

ADPOSSampleStream

public ADPOSSampleStream(InputStream in,
                         String charsetName,
                         boolean expandME,
                         boolean includeFeatures)
Creates a new POSSample stream from a InputStream

Parameters:
in - the Corpus InputStream
charsetName - the charset of the Arvores Deitadas Corpus
expandME - if true will expand the multiword expressions, each word of the expression will have the POS Tag that was attributed to the expression plus the prefix B- or I- (CONLL convention)
includeFeatures - if true will combine the POS Tag with the feature tags
Method Detail

read

public POSSample 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<POSSample>
Returns:
the next object or null to signal that the stream is exhausted
Throws:
IOException

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<POSSample>
Throws:
IOException
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 ObjectStream<POSSample>
Throws:
IOException
