      • predict

        public abstract int predict​(de.jungblut.math.DoubleVector features)
        Returns:
        predicts the index of the outcome, or -1 if not known. In the binary case, 0 and 1 are used to distinguish.

      • transformToByteCode

        public abstract void transformToByteCode​(org.objectweb.asm.MethodVisitor visitor,
                                         org.objectweb.asm.Label returnLabel)
        Transforms this node to byte code, given a visitor that already starts containing the methods and a label that must be jumped to in case of a return.

      • getType

        public abstract byte getType()
        Returns:
        the byte id of the type: leaf = 1, numerical = 2; nominal = 3

      • writeInternal

        protected abstract void writeInternal​(java.io.DataOutput out)
                               throws java.io.IOException
        serialize internal state.
        Throws:
        java.io.IOException

      • write

        public final void write​(java.io.DataOutput out)
                 throws java.io.IOException
        Specified by:
        write in interface org.apache.hadoop.io.Writable
        Throws:
        java.io.IOException

      • read
