Constructor Details

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

Create a new constant array value.

Examples:

Using array of values:

ConstantArray.new(Int32Type, [Int32.new(0), Int32.new(1)])

Using size:

ConstantArray.new(Int32Type, 2) { |i| Int32.new(i) }

Parameters:

  • element_type (Type) —

    Type of values in this aggregate.

  • size_or_values (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 array.
