Method Detail

setDataSize

void setDataSize(long size)

Sets data size. If size is bigger than current size, it will fill it with zeros, otherwise it will shrink current data.

Parameters:

size - target size

setByte

void setByte(long position,
             byte value)

Sets byte to given position.

Parameters:

position - position

value - byte value to be set

insert

void insert(long startFrom,
            long length)

Inserts empty data of given length to given position.

Parameters:

startFrom - position to insert to

length - length of data

insert

void insert(long startFrom,
            XBBlockData insertedData)

Inserts given data to given position.

Parameters:

startFrom - position to insert to

insertedData - data to insert

setData

void setData(XBBlockData newData)

Replaces all data with given data.

Parameters:

newData - source data

insertUninitialized

void insertUninitialized(long startFrom,
                         long length)

Performs insertion of data but doesn't initialize it's value.

Parameters:

startFrom - position to insert to

length - length of data

fillData

void fillData(long startFrom,
              long length)

Fills given area with empty data.

Parameters:

startFrom - position to fill data to

length - length of area

fillData

void fillData(long startFrom,
              long length,
              byte fill)

Fills given area with bytes of given value.

Parameters:

startFrom - position to fill data to

length - length of area

fill - value to fill with

remove

void remove(long startFrom,
            long length)

Removes area of data.

Parameters:

startFrom - position to start removal from

length - length of area

clear

void clear()

Removes all existing data. Simply releases all references to data pages.

loadFromStream

void loadFromStream(java.io.InputStream inputStream)
             throws java.io.IOException

Loads data from given stream.

Parameters:

inputStream - input stream

Throws:

java.io.IOException - if input/output error

getDataOutputStream

java.io.OutputStream getDataOutputStream()

Provides handler for output stream generation.

Returns:

new instance of output stream

loadFromStream

void loadFromStream(java.io.InputStream inputStream,
                    long dataSize)
             throws java.io.IOException

Loads data from given stream expecting given size.

Parameters:

inputStream - input stream

dataSize - data size

Throws:

java.io.IOException - if input/output error
