Methods Summary
public void	bindConstants(Allocation a, int slot) Binds a constant buffer to be used as uniform inputs to the program param a allocation containing uniform data param slot index within the program's list of constant buffer allocations if (slot < 0 || slot >= mConstants.length) { throw new IllegalArgumentException("Slot ID out of range."); } if (a != null && a.getType().getID(mRS) != mConstants[slot].getID(mRS)) { throw new IllegalArgumentException("Allocation type does not match slot type."); } long id = a != null ? a.getID(mRS) : 0; mRS.nProgramBindConstants(getID(mRS), slot, id);
public void	bindSampler(Sampler vs, int slot) Binds an object that describes how a texture at the corresponding location is sampled param vs sampler for a corresponding texture param slot index within the program's list of textures to use the sampler on mRS.validate(); if ((slot < 0) || (slot >= mTextureCount)) { throw new IllegalArgumentException("Slot ID out of range."); } long id = vs != null ? vs.getID(mRS) : 0; mRS.nProgramBindSampler(getID(mRS), slot, id);
public void	bindTexture(Allocation va, int slot) Binds a texture to be used in the program param va allocation containing texture data param slot index within the program's list of textures mRS.validate(); if ((slot < 0) || (slot >= mTextureCount)) { throw new IllegalArgumentException("Slot ID out of range."); } if (va != null && va.getType().hasFaces() && mTextures[slot] != TextureType.TEXTURE_CUBE) { throw new IllegalArgumentException("Cannot bind cubemap to 2d texture slot"); } long id = va != null ? va.getID(mRS) : 0; mRS.nProgramBindTexture(getID(mRS), slot, id);
public Type	getConstant(int slot) Returns the type of the constant buffer used in the program object. It could be used to query internal elements or create an allocation to store constant data. param slot index of the constant input type to return return constant input type if (slot < 0 || slot >= mConstants.length) { throw new IllegalArgumentException("Slot ID out of range."); } return mConstants[slot];
public int	getConstantCount() Program object can have zero or more constant allocations associated with it. This method returns the total count. return number of constant input types return mConstants != null ? mConstants.length : 0;
public int	getTextureCount() Returns the number of textures used in this program object return number of texture inputs return mTextureCount;
public java.lang.String	getTextureName(int slot) Returns the name of the texture input at a given slot. e.g. tex0, diffuse, spec param slot index of the texture input return texture input name if ((slot < 0) || (slot >= mTextureCount)) { throw new IllegalArgumentException("Slot ID out of range."); } return mTextureNames[slot];
public android.renderscript.Program$TextureType	getTextureType(int slot) Returns the type of texture at a given slot. e.g. 2D or Cube param slot index of the texture input return texture input type if ((slot < 0) || (slot >= mTextureCount)) { throw new IllegalArgumentException("Slot ID out of range."); } return mTextures[slot];
