TokenizerStream

public TokenizerStream(Tokenizer tokenizer,
                       ObjectStream<java.lang.String> input)

Method Detail

read

public TokenSample read()
                 throws java.io.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<TokenSample>

Returns:

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

Throws:

java.io.IOException - if there is an error during reading

close

public void close()
           throws java.io.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 java.lang.AutoCloseable

Specified by:

close in interface ObjectStream<TokenSample>

Throws:

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

reset

public void reset()
           throws java.io.IOException,
                  java.lang.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<TokenSample>

Throws:

java.io.IOException - if there is an error during reseting the stream

java.lang.UnsupportedOperationException
