Constructor and Description |
---|
PktHeaderBitReader(ByteArrayInputStream bais)
Instantiates a 'PktHeaderBitReader' that gets the byte data from the
given source.
|
PktHeaderBitReader(RandomAccessIO in)
Instantiates a 'PktHeaderBitReader' that gets the byte data from the
given source.
|
Modifier and Type | Method and Description |
---|---|
(package private) int |
readBit()
Reads a single bit from the input.
|
(package private) int |
readBits(int n)
Reads a specified number of bits and returns them in a single
integer.
|
(package private) void |
setInput(ByteArrayInputStream bais)
Sets the underlying byte based input to the given object.
|
(package private) void |
setInput(RandomAccessIO in)
Sets the underlying byte based input to the given object.
|

This method should always be called when some data has been read directly from the underlying byte based input since the last call to 'readBits()' or 'readBit()' before a new call to any of those methods.
void setInput(RandomAccessIO in)
This method is equivalent to creating a new 'PktHeaderBitReader' object.
