24.6 java.io.ByteArrayOutputStream (JDK 1.0)

This class is a subclass of OutputStream in which data that are written are stored in an internal byte array. The internal array grows as necessary, and can be retrieved with toByteArray() or toString(). The reset() method discards any data currently stored in the internal array and begins storing data from the beginning again. See also CharArrayWriter.

public class ByteArrayOutputStream extends OutputStream {
    // Public Constructors
            public ByteArrayOutputStream();
            public ByteArrayOutputStream(int size);
    // Protected Instance Variables
            protected byte[] buf;
            protected int count;
    // Public Instance Methods
            public synchronized void reset();
            public int size();
            public synchronized byte[] toByteArray();
            public String toString();  // Overrides Object
        1.1  public String toString(String enc) throws UnsupportedEncodingException;
        #   public String toString(int hibyte);
            public synchronized void write(int b);  // Defines OutputStream
            public synchronized void write(byte[] b, int off, int len);  // Overrides OutputStream
            public synchronized void writeTo(OutputStream out) throws IOException;
}
