public class FastInputStream
extends java.io.InputStream
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.

readFast() |
Equivalent to
read() but does not throw
IOException . |
int |
readFast(byte[] toBuf) |
Equivalent to
read(byte[]) but does not throw
IOException . |
int |
readFast(byte[] toBuf,
int offset,
int length) |
Equivalent to
read(byte[],int,int) but does not throw
IOException . |
void |
reset() |
|
long |
skip(long count) |
|
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. |
