PoolStringArray

Strings.

Description

Strings. Optimized for memory usage, does not fragment the memory. Note: This type is passed by value and not by reference. This means that when mutating a class property of type PoolStringArray or mutating a PoolStringArray within an Array or Dictionary, changes will be lost:

  1. var array = [PoolStringArray()]array[0].push_back("hello")print(array)  # [[]] (empty PoolStringArray within an Array)

PoolStringArray property must be reassigned with = for it to be changed:

  1. var array = [PoolStringArray()]var pool_array = array[0]pool_array.push_back("hello")array[0] = pool_arrayprint(array)  # [[hello]] (PoolStringArray with 1 element inside an Array)

    Methods

    Method Descriptions

  • PoolStringArray PoolStringArray ( Array from ) PoolStringArray. Optionally, you can pass in a generic Array that will be converted.
  • append ( String string ) push_back).
  • append_array ( PoolStringArray array ) PoolStringArray at the end of this array.
  • int count ( String value ) Returns the number of times an element is in the array.
  • bool empty ( ) true if the array is empty.
  • fill ( String string ) resize to create an array with a given size and initialized elements.
  • int find ( String value, int from=0 ) -1 if not found. Optionally, the initial search index can be passed. Returns -1 if from is out of bounds.
  • bool has ( String value ) true if the array contains the given value. Note: This is equivalent to using the in operator.
  • int insert ( int idx, String string ) idx == size()).
  • invert ( ) Reverses the order of the elements in the array.
  • String join ( String delimiter ) String with each element of the array joined with the given delimiter.
  • push_back ( String string ) Appends a string element at end of the array.
  • remove ( int idx ) Removes an element from the array by index.
  • 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.
  • int rfind ( String value, int from=-1 ) Searches the array in reverse order. Optionally, a start search index can be passed. If negative, the start index is considered relative to the end of the array. If the adjusted start index is out of bounds, this method searches from the end of the array.
  • set ( int idx, String string ) String at the given index.
  • int size ( ) Returns the number of elements in the array.
  • sort ( ) Sorts the elements of the array in ascending order.
