Class NkStr

  • All Implemented Interfaces:
    java.lang.AutoCloseable, NativeResource, Pointer

    public class NkStr
    extends Struct
    implements NativeResource
    Basic string buffer which is only used in context with the text editor to manage and manipulate dynamic or fixed size string content. This is NOT the default string handling method. The only instance you should have any contact with this API is if you interact with an NkTextEdit object inside one of the copy and paste functions and even there only for more advanced cases.

      • NkStr

        public NkStr​(java.nio.ByteBuffer container)
        Creates a NkStr instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.

      • sizeof

        public int sizeof()
        Description copied from class: Struct
        Returns sizeof(struct).
        Specified by:
        sizeof in class Struct
      • buffer

        public NkBuffer buffer()
        Returns a NkBuffer view of the buffer field.
      • len

        public int len()
        Returns the value of the len field.
      • malloc

        public static NkStr malloc()
        Returns a new NkStr instance allocated with memAlloc. The instance must be explicitly freed.
      • calloc

        public static NkStr calloc()
        Returns a new NkStr instance allocated with memCalloc. The instance must be explicitly freed.
      • create

        public static NkStr create​(long address)
        Returns a new NkStr instance for the specified memory address.
      • createSafe

        @Nullable
        public static NkStr createSafe​(long address)
        Like create, but returns null if address is NULL.
      • malloc

        public static NkStr.Buffer malloc​(int capacity)
        Returns a new NkStr.Buffer instance allocated with memAlloc. The instance must be explicitly freed.
