A packed Array of 64-bit integers.


An Array specifically designed to hold 64-bit integer values. Packs data tightly, so it saves memory for large array sizes.

Note: This type is passed by value and not by reference.

Note: This type stores signed 64-bit integers, which means it can take values in the interval [-2^63, 2^63 - 1], i.e. [-9223372036854775808, 9223372036854775807]. Exceeding those bounds will wrap around. If you only need to pack 32-bit integers tightly, see PackedInt32Array for a more memory-friendly alternative.

Method Descriptions

Constructs a new PackedInt64Array. Optionally, you can pass in a generic Array that will be converted.

  • void append ( int integer )

Appends an element at the end of the array (alias of push_back).

Appends a PackedInt64Array at the end of this array.

Returns true if the array is empty.

Inserts a new integer at a given position in the array. The position must be valid, or at the end of the array (idx == size()).

  • void invert ( )

Reverses the order of the elements in the array.

  • void push_back ( int integer )

Appends a value to the array.

  • void remove ( int idx )

Removes an element from the array by index.

  • void resize ( int idx )

Sets the size of the array. If the array is grown, reserves elements at the end of the array. If the array is shrunk, truncates the array to the new size.

  • void set ( int idx, int integer )

Changes the integer at the given index.

Returns the array size.
