Constructor Detail

FileBufferManager

public FileBufferManager(java.io.FileInputStream stream,
                 java.lang.String encodingName)
                  throws java.io.IOException

Throws:

Method Detail

arrangeCapacity

public boolean arrangeCapacity(int length)
                        throws java.io.IOException

Description copied from class: BufferManager

xxx: This should be an abstract method because in StreamBufferManager CharBuffer capacity doesn't grow

Specified by:

arrangeCapacity in class BufferManager

Throws:

java.io.IOException

getMoreBytes

public java.nio.ByteBuffer getMoreBytes()
                                 throws java.io.IOException

This function gets more data from the file. If there is no more data a ByteBuffer of capacity 'zero' is returned. This function always returns a new ByteBuffer.

Throws:

java.io.IOException

getMore

public boolean getMore()
                throws java.io.IOException

This function returns true if some character data was loaded. Data is available via getCharBuffer(). If before calling this function CharBuffer had some data (i.e. remaining() > 0) then this function first calls CharBuffer.compact() and then it is filled with more data.

Specified by:

getMore in class BufferManager

Returns:

true if some character data was loaded. False value can be assume to be end of current entity.

Throws:

java.io.IOException

main

public static void main(java.lang.String[] args)

close

public void close()
           throws java.io.IOException

Specified by:

close in class BufferManager

Throws:

java.io.IOException

setEncoding

public void setEncoding(java.lang.String encoding)
                 throws java.io.IOException

Specified by:

setEncoding in class BufferManager

Throws:
