Returns the instruction sequence that can convert a value of the current type to
targetType.Returns the instruction sequence that can convert a value of the current type to
targetType.For primitive values the appropriate instructions that perform the necessary widening/narrowing are returned. If this type is a primitive type and the target type is a wrapper type, then the object of the corresponding wrapper type is created and returned.

- def isWiderThan(targetType: NumericType): Boolean
Determines if the range of values captured by
thistype is a strict superset of the range of values captured by values of typetargetType.Determines if the range of values captured by
thistype is a strict superset of the range of values captured by values of typetargetType. Here, strict superset means that – except of rounding issues – the value is conceptually representable bythistype. For example, a conversion from alongvalue to adoublevalue may loose some precision related to the least significant bits, but the value is still representable.In general, the result of
isWiderThanis comparable to the result of determing if a conversion of a value of this type to the given type is an explicit/implicit widening conversion.- Definition Classes

This is generally only useful in very special cases and – to be meaningful at all – it is necessary that the class path used for running the static analysis also contains the classes that are analyzed. This is (often) only the case for the JDK.
However, one example where this is useful is the creation of a real object of a specific type and to use that object when a method is called on that object. This avoids the reimplementation of the respective logic as part of the analysis. For example, if you want to get the
Stringthat is created by a specificStringBufferit is possible to implement the API of StringBuffer as part of your analysis or (probably more efficient) to just create an instance of aStringBufferobject and to redirect every call to the real object. In this case only some general logic is required to redirect calls and to convert the values between the representation used by the analysis and the representation required by the called method. - def toString(): String
