Field Detail

ROLLBACK_ON_RUNTIME_EXCEPTIONS

public static final RollbackRuleAttribute ROLLBACK_ON_RUNTIME_EXCEPTIONS

Constructor Detail

RollbackRuleAttribute

public RollbackRuleAttribute(Class clazz)

Preferred way to construct a RollbackRule, matching the exception class and subclasses. The exception class must be Throwable or a subclass of Throwable.

Parameters:

clazz - throwable class

---

RollbackRuleAttribute

public RollbackRuleAttribute(String exceptionName)

Construct a new RollbackRule for the given exception name. This can be a substring, with no wildcard support at present. A value of "ServletException" would match javax.servlet.ServletException and subclasses, for example.

NB: Consider carefully how specific the pattern is, and whether to include package information (which isn't mandatory). For example, "Exception" will match nearly anything, and will probably hide other rules. "java.lang.Exception" would be correct if "Exception" was meant to define a rule for all checked exceptions. With more unusual exception names such as "BaseBusinessException" there's no need to use a FQN.

Parameters:

exceptionName - the exception pattern (can also be a fully qualified class name)

Method Detail

getExceptionName

public String getExceptionName()

Return the pattern for the exception name.

---

getDepth

public int getDepth(Throwable ex)

Return the depth to the superclass matching. 0 means ex matches exactly. Returns -1 if there's no match. Otherwise, returns depth. Lowest depth wins.

---

equals

public boolean equals(Object other)

Overrides:

equals in class Object

---

hashCode

public int hashCode()

Overrides:

hashCode in class Object

---

toString

public String toString()

Overrides:

toString in class Object

---
