Class FastOutputStream

java.lang.Object
  java.io.OutputStream
      com.sleepycat.util.FastOutputStream

All Implemented Interfaces:

Closeable, Flushable

Direct Known Subclasses:

TupleOutput

public class FastOutputStream
extends OutputStream

A replacement for ByteArrayOutputStream that does not synchronize every byte read.

This class extends OutputStream and its write() methods allow it to be used as a standard output stream. In addition, it provides writeFast() methods that are not declared to throw IOException. IOException is never thrown by this class.

DEFAULT_INIT_SIZE

public static final int DEFAULT_INIT_SIZE

The default initial size of the buffer if no initialSize parameter is specified. This constant is 100 bytes.

See Also:

Constant Field Values

DEFAULT_BUMP_SIZE

public static final int DEFAULT_BUMP_SIZE

The default amount that the buffer is increased when it is full. This constant is zero, which means to double the current buffer size.

Constant Field Values

FastOutputStream

public FastOutputStream()

Creates an output stream with default sizes.

FastOutputStream

public FastOutputStream(int initialSize)

Creates an output stream with a default bump size and a given initial size.

Parameters:

initialSize - the initial size of the buffer.

FastOutputStream

public FastOutputStream(int initialSize,
                        int bumpSize)

Creates an output stream with a given bump size and initial size.

Parameters:

initialSize - the initial size of the buffer.

bumpSize - the amount to increment the buffer.

FastOutputStream

public FastOutputStream(byte[] buffer)

Creates an output stream with a given initial buffer and a default bump size.

Parameters:

buffer - the initial buffer; will be owned by this object.

FastOutputStream

public FastOutputStream(byte[] buffer,
                        int bumpSize)

Creates an output stream with a given initial buffer and a given bump size.

Parameters:

buffer - the initial buffer; will be owned by this object.

bumpSize - the amount to increment the buffer. If zero (the default), the current buffer size will be doubled when the buffer is full.
