public synchronized voidresize(int dimX)
Override the Allocation resize. Resizing adapters is not allowed and will throw a RSInvalidStateException.

param
dimX ignored.

        throw new RSInvalidStateException("Resize not allowed for Adapters.");
public voidsetFace(Type.CubemapFace cf)
Set the active Face. The base allocation must be of a type that includes faces.

param
cf The face to make active.

        if (!mAdaptedAllocation.getType().hasFaces()) {
            throw new RSInvalidStateException("Cannot set Face when the allocation type does not include faces.");
        }

        mSelectedFace = cf;
public voidsetLOD(int lod)
Set the active LOD. The LOD must be within the range for the type being adapted. The base allocation must have mipmaps. Because this changes the dimensions of the adapter the current Y and Z will be reset.

param
lod The LOD to make active.

        if (!mAdaptedAllocation.getType().hasMipmaps()) {
            throw new RSInvalidStateException("Cannot set LOD when the allocation type does not include mipmaps.");

        }

        initLOD(lod);
public voidsetY(int y)
Set the active Y. The y value must be within the range for the allocation being adapted. The base allocation must contain the Y dimension.

param
y The y to make active.

        if (mAdaptedAllocation.getType().getY() == 0) {
            throw new RSInvalidStateException("Cannot set Y when the allocation type does not include Y dim.");
        }

            throw new RSInvalidStateException("Cannot set Y greater than dimension of allocation.");
        }
        if (!mConstrainedY) {
            throw new RSInvalidStateException("Cannot set Y when the adapter includes Y.");
        }

        mSelectedY = y;
public voidsetZ(int z)
Set the active Z. The z value must be within the range for the allocation being adapted. The base allocation must contain the Z dimension.

param
z The z to make active.

        if (mAdaptedAllocation.getType().getZ() == 0) {
            throw new RSInvalidStateException("Cannot set Z when the allocation type does not include Z dim.");
        }
