Package-level declarations

The compile cache has already been enabled before, either by a previous call to {@link enableCompileCache}, or by the NODE_COMPILE_CACHE=dir environment variable. The directory used to store the compile cache will be returned in the directory field in the returned object.

Node.js cannot enable the compile cache because the environment variable NODE_DISABLE_COMPILE_CACHE=1 has been set.

Node.js has enabled the compile cache successfully. The directory used to store the compile cache will be returned in the directory field in the returned object.

Node.js fails to enable the compile cache. This can be caused by the lack of permission to use the specified directory, or various kinds of file system errors. The detail of the failure will be returned in the message field in the returned object.
