Examples of org.springframework.expression.MethodExecutor.execute()

org.springframework.expression.MethodExecutor.execute()
Execute a command using the specified arguments, and using the specified expression state. @param context the evaluation context in which the command is being executed @param target the target object of the call - null for static methods @param arguments the arguments to the executor, should match (in terms of number and type) whatever thecommand will need to run @return the value returned from execution @throws AccessException if there is a problem executing the command or the MethodExecutor is no longer valid

    assertEquals(compiler, actual);
