Examples of org.jacoco.core.analysis.Analyzer

org.jacoco.core.analysis.Analyzer
An {@link Analyzer} instance processes a set of Java class files andcalculates coverage data for them. For each class file the result is reported to a given {@link ICoverageVisitor} instance. In addition the{@link Analyzer} requires a {@link ExecutionDataStore} instance that holdsthe execution data for the classes to analyze. The {@link Analyzer} offersseveral methods to analyze classes from a variety of sources.

    final CoverageBuilder builder = new CoverageBuilder();

    runtime.collect(store, null, false);
    final Analyzer analyzer = new Analyzer(store, builder);
    analyzer.analyzeClass(reader);
    final Collection<IClassCoverage> classes = builder.getClasses();
    assertEquals(1, classes.size(), 0.0);
