    • Constructor Detail

      • UnsynchronizedByteArrayOutputStream

        public UnsynchronizedByteArrayOutputStream()
        Constructs a new ByteArrayOutputStream with a default size of 32 bytes. If more than 32 bytes are written to this instance, the underlying byte array will expand.

      • UnsynchronizedByteArrayOutputStream

        public UnsynchronizedByteArrayOutputStream​(int size)
        Constructs a new ByteArrayOutputStream with a default size of size bytes. If more than size bytes are written to this instance, the underlying byte array will expand.
        Parameters:
        size - initial size for the underlying byte array, must be non-negative.
        Throws:
        java.lang.IllegalArgumentException - if size < 0.

    • Method Detail

      • reset

        public void reset()
        Resets this stream to the beginning of the underlying byte array. All subsequent writes will overwrite any bytes previously stored in this stream.

      • size

        public int size()
        Returns the total number of bytes written to this stream so far.
        Returns:
        the number of bytes written to this stream.

      • toByteArray

        public byte[] toByteArray()
        Returns the contents of this ByteArrayOutputStream as a byte array. Any changes made to the receiver after returning will not be reflected in the byte array returned to the caller.
        Returns:
        this stream's current contents as a byte array.

      • toString

        public java.lang.String toString()
        Returns the contents of this ByteArrayOutputStream as a string. Any changes made to the receiver after returning will not be reflected in the string returned to the caller.
        Overrides:
        toString in class java.lang.Object
        Returns:
        this stream's current contents as a string.

      • toString

        public java.lang.String toString​(java.lang.String enc)
                          throws java.io.UnsupportedEncodingException
        Returns the contents of this ByteArrayOutputStream as a string converted according to the encoding declared in enc.
        Parameters:
        enc - a string representing the encoding to use when translating this stream to a string.
        Returns:
        this stream's current contents as an encoded string.
        Throws:
        java.io.UnsupportedEncodingException - if the provided encoding is not supported.

      • write

        public void write​(byte[] buffer,
                  int offset,
                  int len)
        Writes count bytes from the byte array buffer starting at offset index to this stream.
        Overrides:
        write in class java.io.OutputStream
        Parameters:
        buffer - the buffer to be written.
        offset - the initial position in buffer to retrieve bytes.
        len - the number of bytes of buffer to write.
        Throws:
        java.lang.NullPointerException - if buffer is null.
        java.lang.IndexOutOfBoundsException - if offset < 0 or len < 0, or if offset + len is greater than the length of buffer.

      • write

        public void write​(int oneByte)
        Writes the specified byte oneByte to the OutputStream. Only the low order byte of oneByte is written.
        Specified by:
        write in class java.io.OutputStream
        Parameters:
        oneByte - the byte to be written.

      • writeTo

        public void writeTo​(java.io.OutputStream out)
             throws java.io.IOException
        Takes the contents of this stream and writes it to the output stream out.
        Parameters:
        out - an OutputStream on which to write the contents of this stream.
        Throws:
        java.io.IOException - if an error occurs while writing to out.
