Similar to the method execution join point, the execution join point for the Account(int) constructor encompasses the whole constructor body. The constructor call join points represent the points in other methods that invoke the creation of an object. The following code shows an example of a constructor call join point for the Account object:

In this code, the constructor call join point is the call to the constructor. Just like the method call join point, any code to form the arguments to a constructor, such as method calls to get the arguments, will not be part of the constructor call join point. The discussion of choosing an execution or a call join point for a method applies to constructor join points equally well. Field access join points The join points for field access capture the read and write access to an instance or class member of a class. Note that only access to the data member of a class or aspect is exposed in AspectJ. In other words, join points corresponding to access to local variables in a method are not exposed. The field read access join point captures the read access to an instance or class member of a class. A typical usage of these join points is in advice to ensure that objects are correctly initialized before their use. The following code snippet shows a field read access join point in Account:

In this code snippet, a join point for a field s read access encompasses reading the field as a part of creating the string representation of an object in the toString() method. The field write access join point captures the modification to an instance or class member of a class. These join points are typically used to enforce constraints, such as ensuring the field is within a range of valid values. The following code snippet shows a field write access join point in Account:

public Account(int accountNumber) { _accountNumber = accountNumber; } ... }
Write access join point
In this code snippet, a join point for a field s write access encompasses an assignment to _accountNumber in the constructor. Exception handler execution join points The exception handler execution join points represent the handler block of an exception type. Think of these join points as the catch blocks associated with an exception type. These join points are useful in enforcing certain policies regarding exception handling. This code shows the execution join points:
try { account.debit(amount); } catch (InsufficientBalanceException ex) { postMessage(ex); OverdraftManager.applyOverdraftProtection(account, amount); }
Exception handler join point
In this snippet, the exception handler join point encompasses the whole catch block in this case, the invocation of logging and overdraft protection logic. Class initialization join points The class initialization join points represent the loading of a class, including the initialization of the static portion. These join points are used to perform classlevel crosscutting, such as the initialization of class (static) variables. This code shows the class initialization join points:
public class Account { ... static { try { System.loadLibrary("accounting"); } catch (UnsatisfiedLinkError error) { ... deal with the error } } ... }
Account class initialization
The join point model
The class initialization join point in this code snippet encompasses a call to the System.loadLibary() method and the try/catch block surrounding it. If there were multiple static blocks, the join point will include all of those as well. Note that this join point is present even when you do not have an explicit static block. Such join points still represent the loading of the class and can be used to weave class load-time actions. Object initialization join points The object initialization join points capture the initialization of an object starting from the return of a parent class s constructor until the end of the first called constructor. While class initialization join points are encountered when a class loader loads a class, object initialization occurs when an object is created. Typically, these join points are used in advice that needs to perform certain additional object initialization. This code shows the object initialization join points:
public class SavingsAccount extends Account { ... public SavingsAccount(int accountNumber, boolean isOverdraft) { super(accountNumber); _isOverdraft = isOverdraft; Object } public SavingsAccount(int accountNumber) { this(accountNumber, false); } ... }
