Method Detail

putBoolean

public BitBuffer putBoolean(boolean b)

Description copied from class: BitBuffer

Puts boolean value(Single bit)

Specified by:

putBoolean in class BitBuffer

Parameters:

b - value to set

Returns:

This buffer

putByte

public BitBuffer putByte(byte b)

Description copied from class: BitBuffer

Puts byte value(8 bits)

Specified by:

putByte in class BitBuffer

Parameters:

b - value to set

Returns:

This buffer

putByte

public BitBuffer putByte(byte b,
                         int bits)

Description copied from class: BitBuffer

Puts byte value with specified bit count. Note that this method can only be used with positive numbers or zero.

Specified by:

putByte in class BitBuffer

Parameters:

b - value to set

bits - Number of bits to use

Returns:

This buffer

getBoolean

public boolean getBoolean()

Specified by:

getBoolean in class BitBuffer

Returns:

Binary value of current bit

getByte

public byte getByte()

Specified by:

getByte in class BitBuffer

Returns:

8 bit byte value

getByte

public byte getByte(int bits)

Specified by:

getByte in class BitBuffer

Parameters:

bits - length of value in bits

Returns:

Byte value of given bit width

flip

public void flip()

Description copied from class: BitBuffer

Toggles the buffer betwen read/write modes. Limit is set at current position, and cursor is set at position 0

Specified by:

flip in class BitBuffer

canRead

public boolean canRead()

Specified by:

canRead in class BitBuffer

Returns:

Boolean value telling if the buffer can output data

canWrite

public boolean canWrite()

Specified by:

canWrite in class BitBuffer

Returns:

Boolean value telling if the buffer can accept data

size

public int size()

Specified by:

size in class BitBuffer

Returns:

Size of this buffer, in bits

limit

public int limit()

Specified by:

limit in class BitBuffer

Returns:

Virtual 'end' of this buffer, in bits

position

public int position()

Specified by:

position in class BitBuffer

Returns:

Current position of cursor, in bits

setPosition

public BitBuffer setPosition(int newPosition)

Description copied from class: BitBuffer

Sets cursor position for this buffer

Specified by:

setPosition in class BitBuffer

Returns:

This buffer

asByteArray

public byte[] asByteArray()

Description copied from class: BitBuffer

This method returns representation of this bufer as array of bytes. nota that not-full bits will be set to 0. This method shouldn't affect the position.

Overrides:

asByteArray in class BitBuffer

Returns:

This BitBuffer represented as byte array
