Method Detail

consider

protected void consider(AgentBuilder.RawMatcher matcher,
                        AgentBuilder.Listener listener,
                        TypeDescription typeDescription,
                        java.lang.Class<?> type,
                        JavaModule module)

Does consider the retransformation or redefinition of a loaded type without a loaded type representation.

Parameters:

matcher - The type matcher to apply.

listener - The listener to apply during the consideration.

typeDescription - The type description of the type being considered.

type - The loaded type being considered.

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

consider

protected void consider(AgentBuilder.RawMatcher matcher,
                        AgentBuilder.Listener listener,
                        TypeDescription typeDescription,
                        java.lang.Class<?> type,

                        JavaModule module,
                        boolean unmodifiable)

Does consider the retransformation or redefinition of a loaded type.

Parameters:

matcher - A type matcher to apply.

listener - The listener to apply during the consideration.

typeDescription - The type description of the type being considered.

type - The loaded type being considered.

classBeingRedefined - The loaded type being considered or null if it should be considered non-available.

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

unmodifiable - true if the current type should be considered unmodifiable.
