Class Method Summary

• .from(items : Array(T)) : GodotArray(T)

Instance Method Summary

• #<<(value : T) : self
• #[](index : Int32) : T
• #[]=(index : Int32, value : T) : T
• #[]?(index : Int32) : T | Nil
• #clear : Void
• #each(&block : T -> Void) : Void

  Must yield this collection's elements to the block.

• #empty? : Bool

  Returns true if self does not contain any element.

• #pop : T | Nil
• #push(value : T) : self
• #shift : T | Nil
• #size : Int32

  Returns the number of elements in the collection.
