Method Details

isCachedFrom

public static boolean isCachedFrom(RubyModule target,
 ConstantCache cache)

Check if the given ConstantCache is non-null and valid, given the target module. This method is static to ensure it is inlinable as trivially as possible.

isCached

public static boolean isCached(ConstantCache cache)

Check if the given ConstantCache is non-null and valid. This method is static to ensure it is inlinable as trivially as possible.
