Method Detail

getMaxBufferSize

public long getMaxBufferSize()

Specified by:

getMaxBufferSize in interface ByteBank

Returns:

the maximal size of the buffer

setBytes

public void setBytes(long startpos,
                     byte[] bytes,
                     int offset,
                     int length)

Description copied from interface: ByteBank

Sets the bytes starting form the given position to the values form the provided array.

Specified by:

setBytes in interface ByteBank

Parameters:

startpos - the position in the buffer to start writing from

bytes - the byte array to write

offset - the offset in the bytes array

length - the number of bytes to read

setByte

public void setByte(long pos,
                    byte b)

Description copied from interface: ByteBank

Sets the byte at the given position

Specified by:

setByte in interface ByteBank

Parameters:

pos - the position

b - the value to set

clear

public void clear()

Description copied from interface: ByteBank

Clears the buffer

Specified by:

clear in interface ByteBank

getByte

public byte getByte(long pos)

Specified by:

getByte in interface ByteBank

Parameters:

pos - the position to read from

Returns:

the byte at the given position

getBytes

public int getBytes(long startPos,
                    byte[] b,
                    int offset,
                    int length)

Specified by:

getBytes in interface ByteBank

Parameters:

startPos - the position in the buffer to start reading from

b - the byte array to read into

offset - the offset in the bytes array

length - the number of elements to read into the bytes array

Returns:

number of bytes read

size

public long size()

Specified by:

size in interface ByteBank

Returns:

the offset which follows the last byte stored in this ByteBank

isReadOnly

public boolean isReadOnly()

Specified by:

isReadOnly in interface ByteBank

Returns:

True iff the buffer is read-only.
