    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 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.

    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. Furthermore, the concrete data-structure is always considered an implementation detail and may change at any time.

    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.

case class AnnotatedWith(annotationType: FieldType, elementValuePairs: Seq[ElementValuePair]) extends AnnotationPredicate with Product with Serializable

Tests if an annotation of a class, field, method or method parameter is as specified. The test takes the element values into consideration; if you don't want to take them into consideration use a HasAnnotation predicate.

scala> import org.opalj.br._
scala> import org.opalj.av.checking._
scala> val foo = ObjectType("java/lang/Foo")

scala> val am = AnnotationPredicate("java.lang.Foo",Map("clazz" -> StringValue("")))
am: org.opalj.av.checking.AnnotationPredicate = @java.lang.Foo(clazz="")

scala> am(Annotation(foo,IndexedSeq(ElementValuePair("clazz",StringValue("")))))
res: Boolean = true

scala> am(Annotation(foo,IndexedSeq(ElementValuePair("clazz",StringValue("-+-")))))
res: Boolean = false

scala> val am = DefaultAnnotationPredicate("java.lang.Foo",IndexedSeq.empty)
am: org.opalj.av.checking.DefaultAnnotationPredicate = @java.lang.Foo()

scala> am(Annotation(ObjectType("java/lang/Foo"),IndexedSeq(ElementValuePair("clazz",StringValue(" ")))))
res: Boolean = false

    Checks if the given annotation is as specified by this predicate.

    Checks if the given annotation is as specified by this predicate. Returns true if the given annotation has the type annotationTypeand if all element value pairs are matched independent of their order.

    Example Scenarios

    • If the predicate's annotation type is A and the other annotation's type is B then the elements will not match.
    • If the predicate defines specific org.opalj.br.ElementValuePairs such as ArrayBuffer(ElementValuePair("target", ClassValue("org.opalj.av.checking.AnnotationPredicate")), ElementValuePair("name", StringValue("Annotation_Predicate")) it will then match annotations where the org.opalj.br.ElementValuePairs have a different order: ArrayBuffer(ElementValuePair("name", StringValue("Annotation_Predicate"), ElementValuePair("target", ClassValue("org.opalj.av.checking.AnnotationPredicate"))) But it will not match if one or both of the two org.opalj.br.ElementValuePairs are missing or there is another org.opalj.br.ElementValuePair not defined by this predicate.
