    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.

    This package defines graph algorithms as well as factory methods to describe and compute graphs and trees.

    This package defines graph algorithms as well as factory methods to describe and compute graphs and trees.

    This package supports the following types of graphs:

    1. graphs based on explicitly connected nodes (org.opalj.graphs.Node),
    2. graphs where the relationship between the nodes are encoded externally (org.opalj.graphs.Graph).

    Creates a dot graph which depicts the dominance frontiers.

    isNodeValid

    A function that returns true if the given int value identifies a valid node. If the underlying graph is not a sparse graph; i.e., if every index in the range [0...maxNode] identifies a valid node, then the default function, which always returns true, can be used.

    The nodes/basic blocks on which the given node/basic block is directly control dependent on. That is, the set of nodes which directly control whether x is executed or not. Directly means that there is at least one path between a node Y in Control(X)/*the returned set*/ and X, whose selection is controlled by Y and which contains no nodes that may prevent the execution of X.
