Constructor Detail

DifferentialMatcher

protected DifferentialMatcher(AgentBuilder.RawMatcher ignoreMatcher,
                              List<AgentBuilder.Default.Transformation> transformations,
                              ResettableClassFileTransformer classFileTransformer)

Creates a new differential matcher.

Parameters:

ignoreMatcher - Identifies types that should not be instrumented.

transformations - The transformations to apply on non-ignored types.

classFileTransformer - The class file transformer representing the differential.

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.

Specified by:

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:

true if the entailed AgentBuilder.Transformers should be applied for the given typeDescription.
