case class CaughtException[+V <: Var[V]](pc: PC, exceptionType: Option[ObjectType], throwingStmts: IntTrieSet) extends Stmt[V] with Product with Serializable
A caught exception is essential to ensure that the "throw" is never optimized away, even if the exception object as such is not used.

Textual description of the sources of the caught exceptions. If the exception was thrown by the JVM due to the evaluation of an expression (e.g., NullPointerException, DivisionByZero,..) then the string will be
exception@<INDEX>where index identifies the failing expression. In case an exception is caught that was thrown usingATHROWthe local variable/parameter which stores the local variable is returned. - val exceptionType: Option[ObjectType]

trueif the statement/expression is GUARANTEED to have no externally observable effect if it is not executed.trueif the statement/expression is GUARANTEED to have no externally observable effect if it is not executed. Sideeffect free instructions can be removed if the result of the evaluation of the expression/statement is not used. For those instructions, which may result in an exception, it has to be guaranteed that the exception is NEVER thrown. For example, a div instruction is sideeffect free if it is (statically) known that the divisor is always not equal to zero; otherwise, even if the result value is not used, the expression is not (potentially) side effect free. An array load is only side effect free if the array reference is non-null and if the index is valid.- returns
trueif the expression is GUARENTEED to have no side effect other than wasting some CPU cycles if it is not executed.

- Note
Deeply nested expressions are not supported; i.e. an expression's sub-expressions have to be Var or Const expressions. Generally, a statements expressions have to to simple expressions too - except of the Assignment statement; in the latter case the right-expression can have references to simple expressions. Hence, in case of Assignment statements the side-effect freenes is determined by the referenced expression; in all other cases the side-effect freeness is determined directly by the statement/expression.

The origin(s) of the caught exception(s).
The origin(s) of the caught exception(s). An origin identifies the instruction that ex- or implicitly created the exception:
- If the exception is created locally (
new XXXException) and also caught within the same method, then the origin identifies a normal variable definition site. - If the exception is a parameter the parameter's origin (-1,... -n) is returned.
- If the exception was raised due to a sideeffect of evaluating an expression, then the origin is smaller or equal to org.opalj.ai.ImmediateVMExceptionsOriginOffset and can be tranformed to the index of the responsible instruction using org.opalj.ai#pcOfImmediateVMException.
