    OPAL is a Scala-based framework for the static analysis, manipulation and creation of Java bytecode.

    OPAL is a Scala-based framework for the static analysis, manipulation and creation of Java bytecode. OPAL is designed with performance, scalability and adaptability in mind.

    Its main components are:

    • a library (Common) which provides generally useful data-structures and algorithms for static analyses.
    • a framework for implementing lattice based static analyses (Static Analysis Infrastructure)
    • a framework for parsing Java bytecode (Bytecode Infrastructure) that can be used to create arbitrary representations.
    • a library to create a one-to-one in-memory representation of Java bytecode (Bytecode Disassembler).
    • a library to create a representation of Java bytecode that facilitates writing simple static analyses (Bytecode Representation - org.opalj.br).
    • a scalable, easily customizable framework for the abstract interpretation of Java bytecode (Abstract Interpretation Framework - org.opalj.ai).
    • a library to extract dependencies between code elements and to facilitate checking architecture definitions.
    • a library for the lightweight manipulation and creation of Java bytecode (Bytecode Assembler).

    General Design Decisions

    Thread Safety

    Unless explicitly noted, OPAL is thread safe. I.e., the classes defined by OPAL can be considered to be thread safe unless otherwise stated. (For example, it is possible to read and process class files concurrently without explicit synchronization on the client side.)

    No null Values

    Unless explicitly noted, OPAL does not null values I.e., fields that are accessible will never contain null values and methods will never return null. If a method accepts null as a value for a parameter or returns a null value it is always explicitly documented. In general, the behavior of methods that are passed null values is undefined unless explicitly documented.

    No Typecasts for Collections

    For efficiency reasons, OPAL sometimes uses mutable data-structures internally. After construction time, these data-structures are generally represented using their generic interfaces (e.g., scala.collection.{Set,Map}). However, a downcast (e.g., to add/remove elements) is always forbidden as it would effectively prevent thread-safety.

    Assertions

    OPAL makes heavy use of Scala's Assertion Facility to facilitate writing correct code. Hence, for production builds (after thorough testing(!)) it is highly recommend to build OPAL again using -Xdisable-assertions.

sealed class LoadedClasses extends OrderedProperty with LoadedClassesMetaInformation

Represent the set of types (classes) that were loaded by the VM during execution of the respective org.opalj.br.analyses.Project (which is the entity for this property).

Value Members

  1. final def asOrderedProperty: OrderedProperty

    Returns this if this property inherits from OrderedProperty.

    Returns this if this property inherits from OrderedProperty.

    Used, e.g., by the framework to support debugging analyses.

  2. def bottomness: Int

    Returns a value between zero and 9 which describes how close the value is to its absolute bottom.

    Returns a value between zero and 9 which describes how close the value is to its absolute bottom. Zero means the value is very close to the bottom and 9 means the value is far away from the bottom.

    The default value is "5".

    Tests if this property is equal or better than the given one (better means that the value is above the given value in the underlying lattice.)

  5. def dropOldest(num: Int): Iterator[ObjectType]

    Will return the loaded classes added most recently, dropping the num oldest ones.

  6. final def id: Int

    The id uniquely identifies this property's category.

    The id uniquely identifies this property's category. All property objects of the same kind have to use the same id which is guaranteed since they share the same PropertyKey

  8. def key: PropertyKey[LoadedClasses]

    The key uniquely identifies this property's category.

    The key uniquely identifies this property's category. All property objects of the same kind have to use the same key.

    In general each Property kind is expected to have a companion object that stores the unique PropertyKey.
