Field Detail

buf

protected byte[] buf

The buffer where data is stored.

count

protected int count

The number of valid bytes in the buffer.

startOffset

protected long startOffset

Constructor Detail

DiscardingByteArrayOutputStream

public DiscardingByteArrayOutputStream()

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

DiscardingByteArrayOutputStream

public DiscardingByteArrayOutputStream(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.

Method Detail

get

public byte[] get(long start,
                  int count)

write

public void write(int b)

Writes the specified byte to this byte array output stream.

Specified by:

write in class OutputStream

Parameters:

b - the byte to be written.

write

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

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

Overrides:

write in class OutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

reset

public void reset()

Resets the count field of this byte array output stream 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.

See Also:

ByteArrayInputStream.count

toByteArray

public byte[] toByteArray()

Creates a newly allocated byte array. Its size is the current size of this output stream and the valid contents of the buffer have been copied into it.

Returns:

the current contents of this output stream, as a byte array.

See Also:

ByteArrayOutputStream.size()

size

public int size()

Returns the current size of the buffer.

Returns:

the value of the count field, which is the number of valid bytes in this output stream.

See Also:

ByteArrayOutputStream.count

toString

public String toString()

Converts the buffer's contents into a string decoding bytes using the platform's default character set. The length of the new String is a function of the character set, and hence may not be equal to the size of the buffer. This method always replaces malformed-input and unmappable-character sequences with the default replacement string for the platform's default character set. The CharsetDecoder class should be used when more control over the decoding process is required.

Overrides:

toString in class Object

Returns:

String decoded from the buffer's contents.

Since:

JDK1.1

close

public void close()
           throws IOException

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

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class OutputStream

Throws:

IOException

available

public long available()

Returns the last index that is available.

Returns:

the overall size (not taking discarded bytes into account)

discardTo

public void discardTo(long n)
