Constructor Details

#initialize(size_or_values, &block) {|index| ... } ⇒ ConstantVector

Create a new constant vector value.

Examples:

Using array of values:

ConstantVector.new([Int32.new(0), Int32.new(1)])

Using size:

ConstantVector.new(2) { |i| Int32.new(i) }

Parameters:

  • size_or_values (FFI::Pointer, Array<Value>, Integer) —

    Number of values or array of values.

  • block (Proc) —

    Block evaluated if size is specified.

Yield Parameters:

  • index (Integer) —

    Index of the value in the vector.
