The name of each string function is a good indicator of the functional operation it can perform. The direct analog of string functions is arithmetic functions. We ll look at what JPQL supports in this area next. Arithmetic functions Although math is rarely used to perform CRUD operations, it is useful when trying to manipulate data for reports. JPQL only supports a bare minimum set of functions in this regard, and some vendors may choose to add functions to enhance their reporting capabilities. As with all vendor-specific features, be aware that using them will make your code less portable should you decide to change vendors in the future. You can use arithmetic functions in either the WHERE or HAVING clause of JPQL. Table 10.11 lists all arithmetic functions supported by JPQL.

In this chapter, we presented the JAC framework for dynamic aspect-oriented programming. JAC does not introduce any new keywords nor a compiler, but it provides a framework and an API for programming aspects. In JAC, aspects are run-time entities that can be woven and unwoven while an application is running. Aspects are defined by extending the AspectComponent class which, in JAC, is the root class for all aspects. Among other things, this class defines the pointcut method for defining pointcuts. Pointcuts include two types of joinpoints: method executions and constructor executions. These joinpoints are selected by regular expressions that filter the set of all classes, methods, objects and, when the application is run in distributed mode, hosts. The granularity of a pointcut is the object. Hence, some instances of a class can be included in a pointcut but others cannot. The code executed before and after a joinpoint is defined in a wrapper. Wrappers are classes that implement the AOP Alliance API. They provide methods for the interception and introspection of joinpoints.

JPQL arithmetic functions Arithmetic Functions Description Returns the absolute value of simple_arithmetic_expression Returns the square root value of simple_ arithmetic_expression as a double Returns the result of executing the modulus operation for num, div Returns the number of items in a collection

MDC.put("username", userNameVariable ); logger.debug("writing a log message" );

ABS(simple_arithmetic_expression)

SQRT(simple_arithmetic_expression)

In a JAC application, you can introduce two kinds of code elements: role methods and exception handlers. Both are defined as methods in a wrapper class. JAC is distributed with a library of 16 ready-to-use aspects. These aspects cover a wide range of commonly encountered needs from maintaining persistent data to implementing a GUI. The aspect that carries out the latter functionality may be the most original, and it provides a way of displaying an application through Swing or a web browser. The key mechanism for reusing a JAC aspect is aspect configuration. Configuring an aspect consists of defining which parameters tailor the aspect to a specific application context. Any parameter can be configured; it is up to you to define which part of the aspect to make configurable. The configuration can be changed without recompiling the aspect or the application. It can even be reloaded while the application is running, in which case it dynamically reconfigures the aspects. JAC is distributed with an IDE named UMLAF. You can design, program, compile, and execute a JAC application with this RAD tool. This tool provides a class-diagram view of the application that allows you to graphically design classes and aspects and their relationships.

An appender set up to use the MDC information is similar to the previous NDC example:

MOD(num, div)

SIZE(collection_value_path_expression)

log4j.appender.myappender =org.apache.log4j.ConsoleAppender log4j.appender.myappender.layout=org.apache.log4j.PatternLayout log4j.appender.myappender.layout.ConversionPattern=%X{username} %5p [%t]%m%n

Most of the arithmetic functions are self-explanatory, such as this example of SIZE:
