Method Details

lakosMetrics

@PublicAPI(usage=ACCESS)
public static LakosMetrics lakosMetrics(MetricsComponents<JavaClass> components)

Calculates system architecture metrics as defined by John Lakos. This method is a specific version of lakosMetrics(MetricsComponents, Function) for JavaClasses.

Parameters:

components - The components to calculate the metrics for

Returns:

The calculated LakosMetrics

lakosMetrics

@PublicAPI(usage=ACCESS)
public static <T> LakosMetrics lakosMetrics(MetricsComponents<T> components,
 Function<T,Collection<T>> getDependencies)

Calculates system architecture metrics as defined by John Lakos.

Type Parameters:

T - The type of the elements

Parameters:

components - The components to calculate the metrics for

getDependencies - A function to derive for each element of a component the dependencies to all other elements

Returns:

The calculated LakosMetrics

componentDependencyMetrics

@PublicAPI(usage=ACCESS)
public static ComponentDependencyMetrics componentDependencyMetrics(MetricsComponents<JavaClass> components)

Calculates system component dependency metrics as defined by Robert C. Martin.

Parameters:

components - The components to calculate the metrics for

Returns:

The calculated ComponentDependencyMetrics

visibilityMetrics

@PublicAPI(usage=ACCESS)
public static VisibilityMetrics visibilityMetrics(MetricsComponents<JavaClass> components)

Calculates system component visibility metrics as defined by Herbert Dowalil. This method is a specific version of visibilityMetrics(MetricsComponents, Predicate) where the elements can only be of type JavaClass and a class is considered visible, if and only if it is public.

Parameters:

components - The components to calculate the metrics for

Returns:

The calculated VisibilityMetrics

visibilityMetrics

@PublicAPI(usage=ACCESS)
public static <T> VisibilityMetrics visibilityMetrics(MetricsComponents<T> components,
 Predicate<? super T> isVisible)

Calculates system component visibility metrics as defined by Herbert Dowalil.

Parameters:

components - The components to calculate the metrics for

Returns:

The calculated VisibilityMetrics
