    • Constructor Detail

      • FastByteArrayOutputStream

        public FastByteArrayOutputStream​(int pSize)
        Creates a ByteArrayOutputStream with the given initial buffer size.
        Parameters:
        pSize - initial buffer size

      • FastByteArrayOutputStream

        public FastByteArrayOutputStream​(byte[] pBuffer)
        Creates a ByteArrayOutputStream with the given initial content.

        Note that the buffer is not cloned, for maximum performance.

        Parameters:
        pBuffer - initial buffer

      • write

        public void write​(byte[] pBytes,
                  int pOffset,
                  int pLength)
        Overrides:
        write in class java.io.ByteArrayOutputStream

      • write

        public void write​(int pByte)
        Overrides:
        write in class java.io.ByteArrayOutputStream

      • growIfNeeded

        private void growIfNeeded​(int pNewCount)

      • writeTo

        public void writeTo​(java.io.OutputStream pOut)
             throws java.io.IOException
        Overrides:
        writeTo in class java.io.ByteArrayOutputStream
        Throws:
        java.io.IOException

      • toByteArray

        public byte[] toByteArray()
        Overrides:
        toByteArray in class java.io.ByteArrayOutputStream

      • createInputStream

        public java.io.ByteArrayInputStream createInputStream()
        Creates a ByteArrayInputStream that reads directly from this FastByteArrayOutputStream's byte buffer. The buffer is not cloned, for maximum performance.

        Note that care needs to be taken to avoid writes to this output stream after the input stream is created. Failing to do so, may result in unpredictable behaviour.

        Returns:
        a new ByteArrayInputStream, reading from this stream's buffer.
