Class TypeBindings.TypeParamStash

java.lang.Object

tools.jackson.databind.type.TypeBindings.TypeParamStash

Enclosing class:

TypeBindings

static class TypeBindings.TypeParamStash
extends Object

Helper class that contains simple logic for avoiding repeated lookups via Class.getTypeParameters() as that can be a performance issue for some use cases (wasteful, usually one-off or not reusing mapper). Partly isolated to avoid initialization for cases where no generic types are used.
