public SizeofStruct()

Method Detail

sizeof

public static int sizeof(java.lang.Class<?> c)

Returns the size of the given type. If the given type is a type from CLTypes, then this simply returns its size, e.g.
Sizeof.type(cl_short4) == Sizeof.cl_short4

If the given type is one of the ports of the other cl_* types (e.g. a cl_device_id or cl_command_queue) then the size of a native pointer will be returned.
If the given type extends the Struct class, then the size of the whole structure, including padding that is required for the alignment in OpenCL, is computed and returned.

Otherwise, an IllegalArgumentException is thrown

Parameters:

c - The class

Returns:

The size of the given class

Throws:

java.lang.IllegalArgumentException - If the given class is neither a type from CLTypes, nor a cl_* type, nor a Struct.
