|
byte |
readByte()
Should read a signed byte (i.e., 8 bit) from the input.
|
double |
readDouble()

floating-point number from the input.
|
void |
readFully(byte[] b,
int off,
int n)
Reads up to len bytes of data from this file into an array of
bytes.
|
int |
readInt()
Should read a signed int (i.e., 32 bit) from the input.
|
long |
readLong()
Should read a signed long (i.e., 64 bit) from the input.
|
short |
readShort()
Should read a signed short (i.e., 16 bit) from the input.
|
int |
readUnsignedByte()
Should read an unsigned byte (i.e., 8 bit) from the input.
|
long |
readUnsignedInt()

If the length of the ImageInputStream
is not
-1
, then it is returned after being clamped to
a maximum value of Integer.MAX_VALUE
. If the
ImageInputStream
is -1
, the stream
is read to a maximum position of Integer.MAX_VALUE
and its final position is returned. The position of the stream
is unchanged from the value it had prior to the call.
