Class JITOptions

java.lang.Object

jcuda.driver.JITOptions

public final class JITOptions
extends java.lang.Object

Note: This class should be considered as preliminary, and might change in future releases.

A utility class to circumvent the limitations of Java in terms of interpreting memory areas as pointers or primitive values:

This class allows mapping CUjit_option identifiers to their respective values, so that the options may be passed to methods that require the parameters
unsigned int numOptions, CUjit_option *options, void **optionValues
in the original CUDA API:
