BitInputStream(InputStream in,
ByteOrder byteOrder)
Constructor taking an InputStream and its bit arrangement.
|
Modifier and Type | Method and Description |
---|---|
void |
alignWithByteBoundary()
Drops bits until the next bits will be read from a byte boundary.
|
long |
bitsAvailable()
Returns an estimate of the number of bits that can be read from
this input stream without blocking by the next invocation of a
method for this input stream.
|
int |
bitsCached()
Returns the number of bits that can be read from this input
stream without reading from the underlying input stream at all.
|
void |
clearBitCache()
Clears the cache of bits that have been read from the
underlying stream but not yet provided via
readBits(int) . |
void |
close() |
long |
readBits(int count)
Returns at most 63 bits read from the underlying stream.
