public interface CharIterable extends PrimitiveIterable
CharIterable is an interface which is memory-optimized for char primitives. It is inspired by the interface RichIterable, and contains a subset of the internal iterator methods on RichIterable like collect, sum, etc. The API also includes an external iterator method, which returns an CharIterator. CharIterator helps iterate over the CharIterable without boxing the primitives. This file was automatically generated from template file primitiveIterable.stg.

  • Method Details

    • charIterator

      CharIterator charIterator()
      Returns a primitive iterator that can be used to iterate over the CharIterable in an imperative style.

    • toArray

      char[] toArray()
      Converts the CharIterable to a primitive char array.

    • toArray

      default char[] toArray(char[] target)
      Converts the CharIterable to a primitive char array. If the collection fits into the provided array it is used to store its elements and is returned from the method, otherwise a new array of the appropriate size is allocated and returned. If the iterable is empty, the target array is returned unchanged.
