Examples of org.jacoco.core.analysis.CoverageBuilder

org.jacoco.core.analysis.CoverageBuilder
Builder for hierarchical {@link ICoverageNode} structures based on executionand structure information. The builder is constructed for a given {@link ExecutionDataStore} and then feed with class structure informationthrough its {@link IStructureVisitor} interface. Afterwards the collecteddata can be obtained with {@link #getClasses()}, {@link #getSourceFiles()} or{@link #getBundle(String)}. @author Marc R. Hoffmann @version $Revision: $
