Class PedanticThrowAnalysis

java.lang.Object

soot.toolkits.exceptions.AbstractThrowAnalysis

soot.toolkits.exceptions.PedanticThrowAnalysis

All Implemented Interfaces:

ThrowAnalysis

public class PedanticThrowAnalysis
extends AbstractThrowAnalysis

A ThrowAnalysis that says that every unit can throw every possible exception type. Strictly speaking, this is correct, since the deprecated java.lang.Thread#stop(Throwable) method allows one thread to cause any Throwable it wants to be thrown in another thread, meaning that all Throwables may arrive asynchronously from the perspective of the victim thread.

Constructor Summary

Constructors

Constructor	Description
PedanticThrowAnalysis(Singletons.Global g)	Constructs a PedanticThrowAnalysis for inclusion in Soot's global variable manager, G.

Method Summary

Modifier and Type	Method	Description
ThrowableSet	mightThrow(Unit u)	Returns the set of all Throwables as the set of types that the specified unit might throw, regardless of the unit's identity.
ThrowableSet	mightThrowImplicitly(ThrowInst t)	Returns the set of all Throwables as the set of types that a throw instruction may throw implicitly, that is, the possible types of errors which might arise in the course of executing the throw instruction, rather than the type of the throw's operand.
ThrowableSet	mightThrowImplicitly(ThrowStmt t)	Returns the set of all Throwables as the set of types that a throw statement may throw implicitly, that is, the possible types of errors which might arise in the course of executing the throw statement, rather than the type of the throw's operand.
static PedanticThrowAnalysis	v()	Returns the single instance of PedanticThrowAnalysis.

the set of all Throwables.

mightThrowImplicitly

public ThrowableSet mightThrowImplicitly(ThrowInst t)

Returns the set of all Throwables as the set of types that a throw instruction may throw implicitly, that is, the possible types of errors which might arise in the course of executing the throw instruction, rather than the type of the throw's operand.

the set of all Throwables.

mightThrowImplicitly

public ThrowableSet mightThrowImplicitly(ThrowStmt t)

Returns the set of all Throwables as the set of types that a throw statement may throw implicitly, that is, the possible types of errors which might arise in the course of executing the throw statement, rather than the type of the throw's operand.
