    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.

    In this representation of Java bytecode references to a Java class file's constant pool and to attributes are replaced by direct references to the corresponding constant pool entries.

    In this representation of Java bytecode references to a Java class file's constant pool and to attributes are replaced by direct references to the corresponding constant pool entries. This facilitates developing analyses and fosters comprehension.

    Based on the fact that indirect references to constant pool entries are resolved and replaced by direct references this representation is called the resolved representation.

    This representation of Java bytecode is considered as OPAL's standard representation for writing Scala based analyses. This representation is engineered such that it facilitates writing analyses that use pattern matching.

AnalysisApplication

trait AnalysisApplication extends AnyRef

Provides the necessary infrastructure to easily execute a given analysis that generates some analysis result that can be printed on the command line.

To facilitate the usage of this trait several implicit conversions are defined that wrap standard analyses (org.opalj.br.analyses) such that they report results that are reportable.

This class distinguishes between class files belonging to the code base under analysis and those that belong to the libraries. Those belonging to the libraries are loaded using the ClassFileReader for library classes (basically, all method bodies are skipped org.opalj.br.reader.Java8LibraryFramework). The parameter to specify library classes is -libcp=, the parameter to specify the "normal" classpath is -cp=.

Control Flow

  1. The standard parameters are checked.
  2. The analysis is called to let it verify the analysis specific parameters.
  3. The Project is created.
  4. The analyze method of the Analysis is called with the project and the parameters.
  5. The results are printed.

    The analysis that will be executed.

    The analyze method implemented by the analysis will be called after loading all class files and creating a Project. Additionally, all specified (additional) parameters are passed to the analyze method.

    Checks if the (additional) parameters are understood by the analysis.

    Checks if the (additional) parameters are understood by the analysis. If an error is found, a list of issues is returned and the analysis will not be executed.

    This method must be overridden if the analysis defines additional parameters. A method that overrides this method should return the list of issues if it can't validate all arguments. The default behavior is to check that there are no additional parameters.
