Method Summary | |
---|---|
int |
available()
Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream. |
void |
close()
Close input stream, close connection, and end transaction |
long |
getBlobSize()
Returns the size of the blob if available. |
void |
mark(int readLimit)
Marks the current position in this input stream. |
boolean |
markSupported()
Tests if this input stream supports the mark and
reset methods. |
int |
read()
Reads the next byte of data from the input stream. |
int |
read(byte[] b)
Reads some number of bytes from the input stream and stores them into the buffer array b. |
int |
read(byte[] b,
int off,
int len)
Reads up to len bytes of data from the input stream into an array of bytes. |
void |
reset()
Repositions this stream to the position at the time the mark method was last called on this input stream. |
long |
skip(long n)
Skips over and discards n bytes of data from this input
stream. |

public long getBlobSize()
public boolean markSupported()
mark
and
reset
methods. Whether or not mark
and
reset
are supported is an invariant property of a
particular input stream instance. The markSupported
method
of InputStream
returns false
.
markSupported
in class InputStream
true
if this stream instance supports the mark
and reset methods; false
otherwise.public void mark(int readLimit)
reset
method repositions this stream at the last marked
position so that subsequent reads re-read the same bytes.
The readlimit
arguments tells this input stream to
allow that many bytes to be read before the mark position gets
invalidated.
The general contract of mark
is that, if the method
markSupported
returns true
, the stream somehow
remembers all the bytes read after the call to mark
and
stands ready to supply those same bytes again if and whenever the method
reset
is called. However, the stream is not required to
remember any data at all if more than readlimit
bytes are
read from the stream before reset
is called.
The mark
method of InputStream
does
nothing.

readLimit
- the maximum limit of bytes that can be read before
the mark position becomes invalid.public void reset() throws IOException
mark
method was last called on this input stream.

IOException
public long skip(long n) throws IOException
n
bytes of data from this input
stream. The skip
method may, for a variety of reasons, end
up skipping over some smaller number of bytes, possibly 0
.
This may result from any of a number of conditions; reaching end of file
before n
bytes have been skipped is only one possibility.
The actual number of bytes skipped is returned. If n
is
negative, no bytes are skipped.
