Method Detail

matches

public boolean matches(TypeDescription typeDescription,
                       ClassLoader classLoader,
                       JavaModule module,
                       Class<?> classBeingRedefined,
                       ProtectionDomain protectionDomain)

Decides if the given typeDescription should be instrumented with the entailed AgentBuilder.Transformers.

matches in interface AgentBuilder.RawMatcher

Parameters:

typeDescription - A description of the type to be instrumented.

classLoader - The class loader of the instrumented type. Might be null if this class loader represents the bootstrap class loader.

module - The transformed type's module or null if the current VM does not support modules.

classBeingRedefined - The class being redefined which is only not null if a retransformation is applied.

protectionDomain - The protection domain of the type being transformed.

Returns:
