Modifier and Type | Method and Description |
---|---|
void |
close()
Closes the I/O stream.
|
int |
getPos()
Returns the current position in the stream, which is the position from
where the next byte of data would be read.
|
int |
length()
Returns the current length of the stream, in bytes, taking into account
any buffering.
|
int |
read()
Reads a byte of data from the stream.
|
void |
readFully(byte[] b,
int off,
int len)
Reads up to len bytes of data from this file into an array of
bytes.
|
void |
seek(int off)
Moves the current position for the next read or write operation to
offset.
|
void |
write(int b)
Writes a byte to the stream.
