class
DependencyCollectingDependencyProcessor extends DependencyProcessor
Collects all dependencies extracted by a DependencyExtractor.
Collects all dependencies extracted by a DependencyExtractor.
Thread Safety
This class is thread-safe. However, it does not make sense to call the method toStore unless the dependency extractor that uses this processor has completed.
-
class
DependencyCountingDependencyProcessor extends DependencyProcessor
A dependency processor that just counts the number of dependencies.
A dependency processor that just counts the number of dependencies.
Typically, a
DependencyProcessor
is passed to a DependencyExtractor. The latter calls back theprocessDependency
methods for each identified dependency. -
class
DependencyExtractor extends AnyRef
Traverses a org.opalj.br.SourceElement and identifies all dependencies between the element (org.opalj.br.ClassFile, org.opalj.br.Field or org.opalj.br.Method declaration) and any element it depends on.
Traverses a org.opalj.br.SourceElement and identifies all dependencies between the element (org.opalj.br.ClassFile, org.opalj.br.Field or org.opalj.br.Method declaration) and any element it depends on. The kind of the dependencies that are extracted are defined by the DependencyType enumeration.
Concurrency
The
DependencyExtractor
does not perform any kind of parallelization on its own. Users of aDependencyExtractor
are expected to perform the parallelization (e.g., on the level of source elements) if desired.Thread Safety
The
DependencyExtractor
does not define any relevant state and, hence, this class is thread-safe.However, if multiple dependency extractors are executed concurrently and share the same DependencyProcessor or the same
DepencencyExtractor
is used by multiple threads concurrently, the DependencyProcessor has to be thread-safe.- Note
By default, self dependencies will be reported (e.g., a method that calls itself, a class that defines a field with the same type). If necessary or undesired, self dependencies can easily be filtered by a DependencyProcessor's
,processDependency
method.If the DependencyExtractor is extended, it is important to delegate all creations of
VirtualSourceElements
to the DependencyProcessor to make sure that the dependency processor can perform, e.g., some internalization.

trait
DependencyProcessor extends AnyRef
A dependency processor processes dependencies between two source elements.
A dependency processor processes dependencies between two source elements.
Typically, a
DependencyProcessor
is passed to a DependencyExtractor. The latter calls back theprocessDependency
methods for each identified dependency. -
class
DependencyProcessorAdapter extends DependencyProcessor
Basic implementation of the
DependencyProcessor
trait that does nothing when a dependency is reported. -
class
DependencyProcessorDecorator extends DependencyProcessor
Decorator for a given DependencyProcessor.
Decorator for a given DependencyProcessor.
Usage Scenario
If some special processing of some
VirtualSourceElement
s needs to be done, but in other cases processing should just be delegated to another dependency processor.Thread Safety
This class is thread-safe if the specified base dependency processor is also thread-safe.
-
class
DependencyStore extends AnyRef
Stores extracted dependencies.
Stores extracted dependencies.
Thread Safety
This class is thread safe.

trait
FilterSelfDependencies extends DependencyProcessor
A
DependencyProcessor
that filters self-dependencies.A
DependencyProcessor
that filters self-dependencies.- See also
DependencyStoreWithoutSelfDependenciesKey for a usage.
