    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 - org.opalj.bi) that can be used to create arbitrary representations.
    • a library to create a one-to-one in-memory representation of Java bytecode (Bytecode Disassembler - org.opalj.da).
    • a library to convert this representation to Java class files (Bytecode Creator - org.opalj.bc).
    • a library to create a representation of Java bytecode that facilitates writing simple static analyses (Bytecode Representation - org.opalj.br).
    • a library to create a stackless, three-address code representation of Java bytecode that facilitates writing complex static analyses (Three Address Code - org.opalj.tac).
    • 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 (Dependencies Extraction - org.opalj.de) and to facilitate checking architecture definitions (Architecture Validation - org.opalj.av).
    • a library for the lightweight manipulation and creation of Java bytecode (Bytecode Assembler - org.opalj.ba).
    • a library for parsing Android packages (APK - org.opalj.apk).
    • libraries for writing static analyses using the interprocedural finite distributive subset (IFDS - org.opalj.ifds) and interprocedural distributive environment (IDE - org.opal.ide) algorithms.

    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.

Type Members

  1. trait AssignmentBasedStringInterpreter extends AssignmentLikeBasedStringInterpreter

    Base trait for all string interpreters that only process Assignments, allowing the trait to pre-unpack the assignment target variable as well as the operation performed by AssignmentLikeBasedStringInterpreter.

  2. trait AssignmentLikeBasedStringInterpreter extends StringInterpreter

    Base trait for all string interpreters that only process AssignmentLikeStmts, allowing the trait to pre-unpack the expression of the AssignmentLikeStmt.

  3. class ContextStringAnalysis extends StringAnalysis

    Analyzes a given variable in context of its method in a context-sensitive manner, i.e.

    Analyzes a given variable in context of its method in a context-sensitive manner, i.e. resolving all method parameter references given in the string tree that was resolved for the variable from the ContextFreeStringAnalysis.

  4. case class MethodPC(pc: Int, dm: DefinedMethod) extends Product with Serializable

    Internal entity for the string flow analysis that represents a specific point in a method for which a flow function is requested.

  5. trait ParameterEvaluatingStringInterpreter extends StringInterpreter

    Base trait for all StringInterpreters that have to evaluate parameters at a given call site, thus providing appropriate utility.

  6. trait StringAnalysis extends FPCFAnalysis with StringAnalysisConfig
