Method Detail

withFallbackClassLoader

public FallbackableTypeFactory withFallbackClassLoader(ClassLoader fallbackClassLoader)

"Mutant factory" method which will construct a new instance with specified fallback ClassLoader to use by findClass(java.lang.String) only when main classloader or thread context classloader can not resolve.

withModifier

public FallbackableTypeFactory withModifier(com.fasterxml.jackson.databind.type.TypeModifier mod)

"Mutant factory" method which will construct a new instance with specified TypeModifier added as the first modifier to call (in case there are multiple registered).

Overrides:

withModifier in class com.fasterxml.jackson.databind.type.TypeFactory

withClassLoader

public FallbackableTypeFactory withClassLoader(ClassLoader classLoader)

"Mutant factory" method which will construct a new instance with specified ClassLoader to use by findClass(java.lang.String).

Overrides:

withClassLoader in class com.fasterxml.jackson.databind.type.TypeFactory

withCache

public FallbackableTypeFactory withCache(com.fasterxml.jackson.databind.util.LRUMap<Object,com.fasterxml.jackson.databind.JavaType> cache)

Mutant factory method that will construct new TypeFactory with identical settings except for different cache; most likely one with bigger maximum size.

Overrides:

withCache in class com.fasterxml.jackson.databind.type.TypeFactory

Since:

2.8

defaultInstance

public static FallbackableTypeFactory defaultInstance()

getFallbackClassLoader

public ClassLoader getFallbackClassLoader()

findClass

public Class<?> findClass(String className)
                   throws ClassNotFoundException

If TypeFactory.findClass() cannot find a Class, try with fallback classloader. Main use case: Thread context classloader is KieURLClassLoader (dependency jar) but @class attribute (generated by @JsonTypeInfo(use = Id.CLASS)) may refers to a Class which exists in a different jar/kjar so ProjectClassLoader (or client application classloader) could be a fallback classloader

Overrides:

findClass in class com.fasterxml.jackson.databind.type.TypeFactory

Throws:

ClassNotFoundException
