- abstract def adapt[T](targetType: Type)(implicit typeConversionFactory: TypeConversionFactory[T]): T
Returns the sequence of instructions that adapts values of
thistype to values of the target type.Returns the sequence of instructions that adapts values of
thistype to values of the target type.This method supports the following kind of adaptations:
- boxing
- unboxing

- abstract def id: Int
Each reference type is associated with a unique id.
Each reference type is associated with a unique id. Object types get ids >= 0 and array types get ids < 0.

- abstract def mostPreciseObjectType: ObjectType
Returns the most precise object type that represents this reference type.
Returns the most precise object type that represents this reference type. In case of an
ArrayType, theObjectTypeofjava.lang.Objectis returned; other the currentObjectType. - abstract def toBinaryJavaName: String
Returns the binary name of this type as used by the Java runtime.
Returns the binary name of this type as used by the Java runtime. Basically returns the same name as produced by
Class.getName.- Definition Classes

- abstract def toJavaClass: Class[_]
Returns the Java class object representing this type.
Returns the Java class object representing this type.
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.- Definition Classes
