All known Subclasses: com.sleepycat.bind.tuple.TupleInput,
| FastInputStream | | public class FastInputStream extends InputStream (Code) | | A replacement for ByteArrayInputStream that does not synchronize every
byte read.
This class extends
InputStream and its read()
methods allow it to be used as a standard input stream. In addition, it
provides readFast() methods that are not declared to throw
IOException. IOException is never thrown by this
class.

| Constructor Summary | |
| public | FastInputStream(byte[] buffer)
Creates an input stream. | | public | FastInputStream(byte[] buffer, int offset, int length)
Creates an input stream. |
| Method Summary | |
| public int | available()
| | final public byte[] | getBufferBytes()
Returns the underlying data being read. | | final public int | getBufferLength()
Returns the end of the buffer being read. | | final public int | getBufferOffset()
Returns the offset at which data is being read from the buffer. | | public void | mark(int readLimit)
| | public boolean | markSupported()
| | public int | read()
| | public int | read(byte[] toBuf)
| | public int | read(byte[] toBuf, int offset, int length)
| | final public int | readFast()
Equivalent to read() but does not throw
IOException. | | final public int | readFast(byte[] toBuf)
Equivalent to read(byte[]) but does not throw
IOException. | | final public int | readFast(byte[] toBuf, int offset, int length)
Equivalent to read(byte[],int,int) but does not throw
IOException. | | public void | reset()
| | public long | skip(long count)
| | final public void | skipFast(int count)
Equivalent to skip() but takes an int parameter instead of a
long, and does not check whether the count given is larger than the
number of remaining bytes. |
