Instance Method Summary

• #[](index : Int) : T | Nil

  Returns the element at index, supporting negative indices.

• #[](range : Range) : Array(T | Nil)

  Returns the sub-array for the given Range, supporting negative indices.

• #compact : Array(T)

  Returns a new Array containing only non-null values.

• #each(& : T | Nil -> ) : Nil

  Yields each element (nil for null entries).

• #empty? : Bool

  Returns true if self does not contain any element.

• #finalize
• #inspect(io : IO) : Nil

  Appends a String representation of this object which includes its class name, its object address and the values of all instance variables.

• #length : Int64
• #null?(index : Int) : Bool
• #null_count : Int64
• #ptr : Pointer(LibNanoarrowBridge::ArrowArray)
• #release : Nil
• #released? : Bool
• #size : Int64

  Returns the number of elements in the collection.

• #to_s(io : IO) : Nil

  Appends a short String representation of this object which includes its class name and its object address.

• #to_unsafe : Pointer(LibNanoarrowBridge::ArrowArray)
• #unsafe_get(index : Int64) : T | Nil

  Subclasses implement raw element access (index is already bounds-checked).
