ProgressiveOutputStream(final int size)

Method Summary

Modifier and TypeMethod and Description
private final void
checkFlushBuffer(final boolean forced)

if it's time to flush data (or if forced==true) calls abstract method flushBuffer() and cleans those bytes from own buffer

public final void
close()

Overrides java.io.ByteArrayOutputStream.close.

Implements java.io.Closeable.close.

Closing a ByteArrayOutputStream has no effect.
public final 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.

public final synchronized void
reset()

Overrides java.io.ByteArrayOutputStream.reset.

Resets the count field of this ByteArrayOutputStream to zero, so that all currently accumulated output in the output stream is discarded.

Overrides java.io.ByteArrayOutputStream.close.

Implements java.io.Closeable.close.

Doc from java.io.ByteArrayOutputStream.close.

Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

public final 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.

public final synchronized void reset()

Overrides java.io.ByteArrayOutputStream.reset.

Doc from java.io.ByteArrayOutputStream.reset.

Resets the count field of this ByteArrayOutputStream to zero, so that all currently accumulated output in the output stream is discarded. The output stream can be used again, reusing the already allocated buffer space.

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

Overrides java.io.ByteArrayOutputStream.write.

Doc from java.io.ByteArrayOutputStream.write.

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

Parameters
b:byte[]

the data.

off:int

the start offset in the data.

len:int

the number of bytes to write.

Annotations
@Override

public final void write(final 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.

writeback to summary
public final void write(final int arg0)

Overrides java.io.ByteArrayOutputStream.write.

Doc from java.io.ByteArrayOutputStream.write.

Writes the specified byte to this ByteArrayOutputStream.

Parameters
arg0:int

the byte to be written.
