Interface AgentBuilder.FallbackStrategy

All Known Implementing Classes:
AgentBuilder.FallbackStrategy.ByThrowableType, AgentBuilder.FallbackStrategy.Simple
Enclosing interface:
AgentBuilder
public static interface AgentBuilder.FallbackStrategy
A fallback strategy allows to reattempt a transformation or a consideration for redefinition/retransformation in case an exception occurs. Doing so, it is possible to use a TypePool rather than using a loaded type description backed by a Class. Loaded types can raise exceptions and errors if a ClassLoader cannot resolve all types that this class references. Using a type pool, such errors can be avoided as type descriptions can be resolved lazily, avoiding such errors.
