Class AbstractThrowAnalysis

java.lang.Object
  soot.toolkits.exceptions.AbstractThrowAnalysis

All Implemented Interfaces:

ThrowAnalysis

Direct Known Subclasses:

PedanticThrowAnalysis, UnitThrowAnalysis

public abstract class AbstractThrowAnalysis
extends Object
implements ThrowAnalysis

Abstract class implementing parts of the ThrowAnalysis interface which may be common to multiple concrete ThrowAnalysis classes. AbstractThrowAnalysis provides straightforward implementations of mightThrowExplicitly(ThrowInst) and mightThrowExplicitly(ThrowStmt), since concrete implementations of ThrowAnalysis seem likely to differ mainly in their treatment of implicit exceptions.

Constructor Summary

AbstractThrowAnalysis()

Method Summary

abstract ThrowableSet	mightThrow(Unit u) Returns a set representing the Throwable types that the specified unit might throw.
ThrowableSet	mightThrowExplicitly(ThrowInst t) Returns a set representing the Throwable types that the specified throw instruction might throw explicitly, that is, the possible types for its Throwable argument.
ThrowableSet	mightThrowExplicitly(ThrowStmt t) Returns a set representing the Throwable types that the specified throw statement might throw explicitly, that is, the possible types for its Throwable argument.
abstract ThrowableSet	mightThrowImplicitly(ThrowInst t) Returns a set representing the Throwable types that the specified throw instruction might 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.
abstract ThrowableSet	mightThrowImplicitly(ThrowStmt t) Returns a set representing the Throwable types that the specified throw statement might 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.

Method Detail

mightThrow

public abstract ThrowableSet mightThrow(Unit u)

Description copied from interface: ThrowAnalysis

Returns a set representing the Throwable types that the specified unit might throw.

Specified by:

mightThrow in interface ThrowAnalysis

Parameters:

u - Unit whose exceptions are to be returned.

Returns:

a representation of the Throwable types that u might throw.

mightThrowExplicitly

public ThrowableSet mightThrowExplicitly(ThrowInst t)

Description copied from interface: ThrowAnalysis

Returns a set representing the Throwable types that the specified throw instruction might throw explicitly, that is, the possible types for its Throwable argument.

Specified by:

mightThrowExplicitly in interface ThrowAnalysis

Parameters:

t - ThrowInst whose explicit exceptions are to be returned.

Returns:

a representation of the possible types of t's Throwable operand.

mightThrowExplicitly

public ThrowableSet mightThrowExplicitly(ThrowStmt t)

Description copied from interface: ThrowAnalysis

Returns a set representing the Throwable types that the specified throw statement might throw explicitly, that is, the possible types for its Throwable argument.

Specified by:

mightThrowExplicitly in interface ThrowAnalysis

Parameters:

t - ThrowStmt whose explicit exceptions are to be returned.

Returns:

a representation of the possible types of t's Throwable operand.

mightThrowImplicitly

public abstract ThrowableSet mightThrowImplicitly(ThrowInst t)

Description copied from interface: ThrowAnalysis

Returns a set representing the Throwable types that the specified throw instruction might 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.

Specified by:

mightThrowImplicitly in interface ThrowAnalysis

Parameters:

t - ThrowStmt whose implicit exceptions are to be returned.

Returns:

a representation of the types of exceptions that t might throw implicitly.

mightThrowImplicitly

public abstract ThrowableSet mightThrowImplicitly(ThrowStmt t)

Description copied from interface: ThrowAnalysis

Returns a set representing the Throwable types that the specified throw statement might 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.

Specified by:

mightThrowImplicitly in interface ThrowAnalysis

Parameters:

t - ThrowStmt whose implicit exceptions are to be returned.

Returns:

a representation of the types of exceptions that t might throw implicitly.
