All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class ByteArrayBuffer
extends OutputStream

Read/write buffer that stores a sequence of bytes.

It works in a way similar to ByteArrayOutputStream but this class works better in the following ways:

1. no synchronization
2. offers a newInputStream() that creates a new InputStream that won't cause buffer reallocation.
3. less parameter correctness checking
4. offers a write(InputStream) method that reads the entirety of the given InputStream without using a temporary buffer.

Field Detail

buf

protected byte[] buf

The buffer where data is stored.

Constructor Detail

ByteArrayBuffer

public ByteArrayBuffer()

Creates a new byte array output stream. The buffer capacity is initially 32 bytes, though its size increases if necessary.

ByteArrayBuffer

public ByteArrayBuffer(int size)

Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

Parameters:

size - the initial size.

Throws:

IllegalArgumentException - if size is negative.

ByteArrayBuffer

public ByteArrayBuffer(byte[] data)

ByteArrayBuffer

public ByteArrayBuffer(byte[] data,
                       int length)

Method Detail

write

public final void write(InputStream in)
                 throws IOException

Reads all the data of the given InputStream and appends them into this buffer.

Throws:

IOException - if the read operation fails with an IOException.

write

public final void write(int b)

Specified by:

write in class OutputStream

write

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

Overrides:

write in class OutputStream

writeTo

public final void writeTo(OutputStream out)
                   throws IOException

Throws:

IOException

reset

public final void reset()

toByteArray

public final byte[] toByteArray()

Deprecated.

this method causes a buffer reallocation. Use it only when you have to.

Gets the copy of exact-size byte[] that represents the written data.

Since this method needs to allocate a new byte[], this method will be costly.

size

public final int size()

getRawData

public final byte[] getRawData()

Gets the underlying buffer that this ByteArrayBuffer uses. It's never small than its size(). Use with caution.

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException

newInputStream

public final InputStream newInputStream()

Creates a new InputStream that reads from this buffer.

newInputStream

public final InputStream newInputStream(int start,
                                        int length)

Creates a new InputStream that reads a part of this bfufer.

toString

public String toString()

Decodes the contents of this buffer by the default encoding and returns it as a string.

Meant to aid debugging, but no more.

Overrides:

toString in class Object
