pack-priv Class AppendStream

extends OutputStream
Class Inheritance
Imports
java.io.IOException, .InputStream, .OutputStream, .RandomAccessFile
A stream for writing to the temp file, and when done can return a stream for reading the data just written.

Note

We assume that only one thread is writing to the file at a time.

public synchronized void
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 synchronized InputStream
getInputStream()

public void
write(int
the byte.
b)

Implements abstract java.io.OutputStream.write.

Writes the specified byte to this output stream.
public void
write(byte[]
the data.
b)

Overrides java.io.OutputStream.write.

Writes b.length bytes from the specified byte array to this output stream.
public void
write(byte[]
the data.
b, int
the start offset in the data.
off, int
the number of bytes to write.

Method Detail

closeback to summary
public synchronized 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.

Annotations
@Override
Exceptions
IOException:
if an I/O error occurs.
getInputStreamback to summary
public synchronized InputStream getInputStream() throws IOException
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.

Parameters
b:int

the byte.

Annotations
@Override
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).

Parameters
b:byte[]

the data.

Annotations
@Override
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.

Parameters
b:byte[]

the data.

off:int

the start offset in the data.

len:int

the number of bytes to write.

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