  • Method Details

    • createWithBase

      public static <A, B> PMatrixByteBuffered2x2s32<A,B> createWithBase(ByteBuffer b, com.io7m.mutable.numbers.core.MutableLongType base, int offset)

      Return a new vector that is backed by the given byte buffer b

      The data for the instance will be taken from the data at the current value of base.get() + offset, each time a field is requested or set.

      No initialization of the data is performed.

      Type Parameters:
      A - A phantom type parameter (possibly representing a source coordinate system)
      B - A phantom type parameter (possibly representing a target coordinate system)
      Parameters:
      b - The byte buffer
      base - The base address
      offset - A constant offset
      Returns:
      A new buffered vector
