Class GenericsInfoFactory

java.lang.Object

ru.vyarus.java.generics.resolver.context.GenericsInfoFactory

public final class GenericsInfoFactory
extends java.lang.Object

Analyze class hierarchy and produce object with resolved generics for each class. Resolved generics descriptors are cached (for not inlying contexts).

Note: when ignore classes used, cache will not work: such descriptors are always resolved.

Cache may be disabled (e.g. when JRebel used) by using environment variable or system property e.g.: System.setProperty(GenericsInfoFactory.CACHE_PROPERTY, 'false'). Property value checked on cache write. To clear current cache state use static method.

Method Detail

create

public static GenericsInfo create(java.lang.Class<?> type,
                                  java.lang.Class<?>... ignoreClasses)

Note: ignore classes switch off caching for resolved descriptor (and if completely resolved version contained in cache limited version will be composed one more time).

Parameters:

type - finder type to investigate

ignoreClasses - list of classes to ignore during inspection (useful to avoid interface clashes)

Returns:

descriptor for class hierarchy generics substitution

clearCache

public static void clearCache()

Clears cached descriptors (already parsed). Cache could be completely disabled using system property or environment variable
