IntLikeType

sealed abstract class IntLikeType extends NumericType with CTIntType

An IntLikeType is every type (byte, char, short and int) that uses a primitive int to store the current value and which has explicit support in the JVM.

Source
Type.scala
Note

Boolean values are (at least conceptually) also stored in ints. However, the JVM has basically no explicit support for booleans (e.g., a conversion of an int value to a boolean is not directly supported).

  3. abstract def atype: Int

    The atype value of the base type.

    The atype value of the base type. The atype value uniquely identifies a base type and is used primarily by the [instruction.NEWARRAY] instruction.

  5. abstract def convertTo[T](targetType: NumericType)(implicit typeConversionFactory: TypeConversionFactory[T]): T

    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.

    Note

    The functionality implemented here, basically implements the logic for handling boxing and unboxing operations.

  6. abstract def id: Int

    The unique id of this type.

    The unique id of this type. Types are associated with globally unique ids to make it easy to define a global order. The id Int.MinValue is used for Void; Int.MinValue + 1 is used for CTIntType.

  7. abstract def isWiderThan(targetType: NumericType): Boolean

    Determines if the range of values captured by this type is a strict superset of the range of values captured by values of type targetType.

    Determines if the range of values captured by this type is a strict superset of the range of values captured by values of type targetType. Here, strict superset means that – except of rounding issues – the value is conceptually representable by this type. For example, a conversion from a long value to a double value may loose some precision related to the least significant bits, but the value is still representable.

    In general, the result of isWiderThan is 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.

    Example:
    1. assert(IntegerType.isWiderThan(IntegerType) == false)
      assert(IntegerType.isWiderThan(LongType) == false)
      assert(IntegerType.isWiderThan(ByteType) == true)
      assert(LongType.isWiderThan(FloatType) == false)
      assert(ByteType.isWiderThan(CharType) == false)
      assert(LongType.isWiderThan(ShortType) == true)
  8. abstract def toBinaryJavaName: String

    Returns the binary name of this type as used by the Java runtime.

  11. 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 String that is created by a specific StringBuffer it is possible to implement the API of StringBuffer as part of your analysis or (probably more efficient) to just create an instance of a StringBuffer object 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.
