public abstract class ShaderAttributeObject extends ShaderAttribute
attrName
is explicitly set to the specified value during
rendering. attrName must be the name of a valid
uniform attribute in the shader in which it is used. Otherwise, the
attribute name will be ignored and a runtime error may be
generated. The value must be an instance of one of the
allowed classes or an array of one the allowed classes. The allowed
classes are: Integer, Float,
Tuple{2,3,4}{i,f},
Matrix{3,4}f. A ClassCastException will be thrown
if a specified value object is not one of the allowed
types. Further, the type of the value is immutable once a
ShaderAttributeObject is constructed. Subsequent setValue
operations must be called with an object of the same type as the
one that was used to construct the ShaderAttributeObject. Finally,
the type of the value object must match the type of
the corresponding attrName variable in the shader in
which it is used. Otherwise, the shader will not be able to use the
attribute and a runtime error may be generated.ShaderAttributeSet,
