public interface ReadBuffer

a buffer interface with methods to read and to position the read pointer in the buffer.

Method Summary

Methods

Modifier and Type	Method and Description
int	offset() returns the current offset in the buffer
BitMap4	readBitMap(int bitCount)
byte	readByte() reads a byte from the buffer.
void	readBytes(byte[] bytes) reads an array of bytes from the buffer.
int	readInt() reads an int from the buffer.
long	readLong() reads a long from the buffer.
void	seek(int offset) positions the read pointer at the specified position

Method Detail

offset

int offset()

returns the current offset in the buffer

Returns:

the offset

readBitMap

BitMap4 readBitMap(int bitCount)

readByte

byte readByte()

reads a byte from the buffer.

Returns:

the byte

readBytes

void readBytes(byte[] bytes)

reads an array of bytes from the buffer. The length of the array that is passed as a parameter specifies the number of bytes that are to be read. The passed bytes buffer parameter is directly filled.

Parameters:

bytes - the byte array to read the bytes into.

readInt

int readInt()

reads an int from the buffer.

Returns:

the int

readLong

long readLong()

reads a long from the buffer.

Returns:

the long

seek

void seek(int offset)

positions the read pointer at the specified position

Parameters:

offset - the desired position in the buffer
