Interface IntIndexData

All Superinterfaces:
com.badlogic.gdx.utils.Disposable
All Known Implementing Classes:
IntIndexArray, IntIndexBufferObject, IntIndexBufferObjectSubData
public interface IntIndexData
extends com.badlogic.gdx.utils.Disposable
An IntIndexData instance holds index data. Can be either a plain int buffer or an OpenGL buffer object. Reimplementation using 32-bit integer indices instead of shorts.

  • Method Summary

    Modifier and Type Method Description
    void bind()
    Binds this IntIndexBufferObject for rendering with glDrawElements.
    void dispose()
    Disposes this IndexDatat and all its associated OpenGL resources.
    java.nio.IntBuffer getBuffer()
    Returns the underlying IntBuffer.
    int getNumIndices()  
    int getNumMaxIndices()  
    void invalidate()
    Invalidates the IntIndexBufferObject so a new OpenGL buffer handle is created.
    void setIndices​(int[] indices, int offset, int count)
    Sets the indices of this IntIndexBufferObject, discarding the old indices.
    void setIndices​(java.nio.IntBuffer indices)
    Copies the specified indices to the indices of this IntIndexBufferObject, discarding the old indices.
    void unbind()
    Unbinds this IntIndexBufferObject.
    void updateIndices​(int targetOffset, int[] indices, int offset, int count)
    Update (a portion of) the indices.

  • Method Details

    • getNumIndices

      int getNumIndices()
      Returns:
      the number of indices currently stored in this buffer

    • getNumMaxIndices

      int getNumMaxIndices()
      Returns:
      the maximum number of indices this IntIndexBufferObject can store.

    • setIndices

      void setIndices​(int[] indices, int offset, int count)

      Sets the indices of this IntIndexBufferObject, discarding the old indices. The count must equal the number of indices to be copied to this IntIndexBufferObject.

      This can be called in between calls to bind() and unbind(). The index data will be updated instantly.

      Parameters:
      indices - the index data
      offset - the offset to start copying the data from
      count - the number of ints to copy

    • setIndices

      void setIndices​(java.nio.IntBuffer indices)
      Copies the specified indices to the indices of this IntIndexBufferObject, discarding the old indices. Copying start at the current Buffer.position() of the specified buffer and copied the Buffer.remaining() amount of indices. This can be called in between calls to bind() and unbind(). The index data will be updated instantly.
      Parameters:
      indices - the index data to copy

    • updateIndices

      void updateIndices​(int targetOffset, int[] indices, int offset, int count)
      Update (a portion of) the indices.
      Parameters:
      targetOffset - offset in indices buffer
      indices - the index data
      offset - the offset to start copying the data from
      count - the number of ints to copy

    • getBuffer

      java.nio.IntBuffer getBuffer()

      Returns the underlying IntBuffer. If you modify the buffer contents they wil be uploaded on the call to bind(). If you need immediate uploading use setIndices(int[], int, int).

      Returns:
      the underlying int buffer.

    • bind

      void bind()
      Binds this IntIndexBufferObject for rendering with glDrawElements.

    • unbind

      void unbind()
      Unbinds this IntIndexBufferObject.

    • invalidate

      void invalidate()
      Invalidates the IntIndexBufferObject so a new OpenGL buffer handle is created. Use this in case of a context loss.

    • dispose

      void dispose()
      Disposes this IndexDatat and all its associated OpenGL resources.
      Specified by:
      dispose in interface com.badlogic.gdx.utils.Disposable
