execute

                                                                                               ThrowableConsumer<E> callback)

Execute an Executable instance

Type Parameters:

E - The type or subtype of Executable

Parameters:

object - Executable instance, Field, Method or Constructor

callback - the call back to execute Executable object

Throws:

java.lang.NullPointerException - If executableMember is null

java.lang.IllegalStateException - if this executableMember object is enforcing Java language access control and the underlying executable member is inaccessible.

java.lang.IllegalArgumentException - if the executable member is an instance executable member and the specified object argument is not an instance of the class or interface declaring the underlying executable member (or of a subclass or implementor thereof); if the number of actual and formal parameters differ; if an unwrapping conversion for primitive arguments fails; or if, after possible unwrapping, a parameter value cannot be converted to the corresponding formal parameter type by a executable member invocation conversion.

java.lang.RuntimeException - if the underlying executable member throws an exception.
