Field Detail

classAssignabilityMap

protected final ConcurrentHashMap<Class<?>,ConcurrentHashMap<Class<?>,Boolean>> classAssignabilityMap

This map stores for a class name, which other class names have been found to be assignable to it.

In more detail:

• For a given class name (outer), you get back a map.
• Each entry is a tuple of another class name (inner) and a boolean that states whether or not you can assign the inner class to the outer class.

TODO: This map can grow quite fast, theoretically up to n^2; n = # of classes

Method Detail

isAssignableFrom

public boolean isAssignableFrom(Class<?> clazz,
                                Class<?> other)

Checks if the 'clazz' class is assignable from the 'other' class.

Identical to clazz.isAssignableFrom(other), but might use caching to speed up resolution. This is useful if Java 5 (or earlier) is used, as these use a much slower implementation than Java 6+.

TODO: Disable caching as soon as Java 5 has been deprecated for Jenkins

Parameters:

clazz - the class to which 'other' must be assignable (left-hand value)

other - the class which must be assignable to 'clazz' (right-hand value)

Returns:

true, if 'other' is a subtype of 'clazz.
