Constructor Details

#initialize(overloaded, size = 0) ⇒ VectorType

Create a new vector type from a pointer or a type.

Parameters:

  • overloaded (FFI::Pointer, Type) —

    Pointer to existing vector type or Type of object stored in the vector.

  • size (Integer) (defaults to: 0) —

    Number of objects in this vector type.
