pack-priv final Class MultipartEntryNIOInputStream

Overrides java.io.InputStream.available.

Doc from java.io.InputStream.available.

Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected. The read might be on the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes.

Note that while some implementations of InputStream will return the total number of bytes in the stream, many will not. It is never correct to use the return value of this method to allocate a buffer intended to hold all data in this stream.

A subclass's implementation of this method may choose to throw an IOException if this input stream has been closed by invoking the close() method.

Closes this input stream and releases any system resources associated with the stream.

Implements org.glassfish.grizzly.http.io.BinaryNIOInputSource.getBuffer.

Doc from org.glassfish.grizzly.http.io.BinaryNIOInputSource.getBuffer.

Returns the the duplicate of the underlying org.glassfish.grizzly.Buffer that backs this InputSource. The content of the returned buffer will be that of the underlying buffer. Changes to returned buffer's content will be visible in the underlying buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

Overrides java.io.InputStream.mark.

Doc from java.io.InputStream.mark.

Marks the current position in this input stream. A subsequent call to the 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.

Marking a closed stream should not have any effect on the stream.

Returns:boolean

Implements org.glassfish.grizzly.InputSource.notifyAvailable.

Doc from org.glassfish.grizzly.InputSource.notifyAvailable.

Notify the specified ReadHandler when any number of bytes or characters can be read without blocking.

Invoking this method is equivalent to calling: notifyAvailable(handler, 1).

@Override

Implements org.glassfish.grizzly.InputSource.notifyAvailable.

Doc from org.glassfish.grizzly.InputSource.notifyAvailable.

Notify the specified ReadHandler when the number of bytes that can be read without blocking is greater or equal to the specified size.

@Override

Implements abstract java.io.InputStream.read.

Doc from java.io.InputStream.read.

Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

IOException:

if an I/O error occurs.

Overrides java.io.InputStream.read.

Doc from java.io.InputStream.read.

Reads up to len bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer.

This method blocks until input data is available, end of file is detected, or an exception is thrown.

If len is zero, then no bytes are read and 0 is returned; otherwise, there is an attempt to read at least one byte. If no byte is available because the stream is at end of file, the value -1 is returned; otherwise, at least one byte is read and stored into b.

The first byte read is stored into element b[off], the next one into b[off+1], and so on. The number of bytes read is, at most, equal to len. Let k be the number of bytes actually read; these bytes will be stored in elements b[off] through b[off+k-1], leaving elements b[off+k] through b[off+len-1] unaffected.

In every case, elements b[0] through b[off-1] and elements b[off+len] through b[b.length-1] are unaffected.

IOException:

If the first byte cannot be read for any reason other than end of file, or if the input stream has been closed, or if some other I/O error occurs.

Implements org.glassfish.grizzly.http.io.BinaryNIOInputSource.readBuffer.

Doc from org.glassfish.grizzly.http.io.BinaryNIOInputSource.readBuffer.

Returns the underlying org.glassfish.grizzly.Buffer that backs this InputSource. Unlike getBuffer(), this method detaches the returned Buffer, so user becomes responsible for handling the Buffer's life-cycle.

@Override

Implements org.glassfish.grizzly.http.io.BinaryNIOInputSource.readBuffer.

Doc from org.glassfish.grizzly.http.io.BinaryNIOInputSource.readBuffer.

Returns the org.glassfish.grizzly.Buffer of a given size, which represents a chunk of the underlying org.glassfish.grizzly.Buffer that backs this InputSource. Unlike getBuffer(), this method detaches the returned Buffer, so user becomes responsible for handling the Buffer's life-cycle.

@Override

Overrides java.io.InputStream.reset.

Doc from java.io.InputStream.reset.

Repositions this stream to the position at the time the mark method was last called on this input stream.

The general contract of reset is:

• If the method markSupported returns true, then:
  • If the method mark has not been called since the stream was created, or the number of bytes read from the stream since mark was last called is larger than the argument to mark at that last call, then an IOException might be thrown.
  • If such an IOException is not thrown, then the stream is reset to a state such that all the bytes read since the most recent call to mark (or since the start of the file, if mark has not been called) will be resupplied to subsequent callers of the read method, followed by any bytes that otherwise would have been the next input data as of the time of the call to reset.
• If the method markSupported returns false, then:
  • The call to reset may throw an IOException.
  • If an IOException is not thrown, then the stream is reset to a fixed state that depends on the particular type of the input stream and how it was created. The bytes that will be supplied to subsequent callers of the read method depend on the particular type of the input stream.

Exceptions

IOException:

if this stream has not been marked or if the mark has been invalidated.

Overrides java.io.InputStream.skip.

Doc from java.io.InputStream.skip.

Skips over and discards 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, the skip method for class InputStream always returns 0, and no bytes are skipped. Subclasses may handle the negative value differently.
