pack-priv Class PlaceholderOutputStream

Located in compilation unit of sun.net.httpserver.ExchangeImpl.

extends OutputStream
Class Inheritance

An OutputStream which wraps another stream which is supplied either at creation time, or sometime later. If a caller/user tries to write to this stream before the wrapped stream has been provided, then an IOException will be thrown.

close()

Overrides java.io.OutputStream.close.

Implements java.io.Closeable.close.

Closes this output stream and releases any system resources associated with this stream.

public void
flush()

Overrides java.io.OutputStream.flush.

Implements java.io.Flushable.flush.

Flushes this output stream and forces any buffered output bytes to be written out.

pack-priv boolean
pack-priv void
public void
write(int b)

Implements abstract java.io.OutputStream.write.

Writes the specified byte to this output stream.

public void
write(byte[] b)

Overrides java.io.OutputStream.write.

Writes b.length bytes from the specified byte array to this output stream.

public void
write(byte[] b, int off, int len)

Overrides java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream.

private void checkWrap() throws IOException
closeback to summary
public void close() throws IOException

Overrides java.io.OutputStream.close.

Implements java.io.Closeable.close.

Doc from java.io.OutputStream.close.

Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

Exceptions
IOException:
if an I/O error occurs.
flushback to summary
public void flush() throws IOException

Overrides java.io.OutputStream.flush.

Implements java.io.Flushable.flush.

Doc from java.io.OutputStream.flush.

Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.

Exceptions
IOException:
if an I/O error occurs.

writeback to summary
public void write(int b) throws IOException

Implements abstract java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Exceptions
IOException:
if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.
writeback to summary
public void write(byte[] b) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes b.length bytes from the specified byte array to this output stream. The general contract for write(b) is that it should have exactly the same effect as the call write(b, 0, b.length).

Exceptions
IOException:
if an I/O error occurs.
writeback to summary
public void write(byte[] b, int off, int len) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Exceptions
IOException:
if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.
