The artifact pattern syntax is of the form: 27 * 28 * <pre> 29 * [groupId]:[artifactId]:[extension]:[version] 30 * </pre> 31 * <p> 32 * Where each pattern segment is optional and supports full and partial <code>*</code> wildcards. An empty pattern 33 * segment is treated as an implicit wildcard. Version can be a range in case a {@code VersionScheme} is specified. 34 * </p> 35 * <p> 36 * For example, <code>org.apache.*</code> would match all artifacts whose group id started with 37 * <code>org.apache.</code> , and <code>:::*-SNAPSHOT</code> would match all snapshot artifacts. 38 * </p> 39 * 40 * @author Robert Scholte 41 * @since 3.0 42 * @see org.eclipse.aether.util.filter.PatternExclusionsDependencyFilter 43 * @see org.eclipse.aether.version.VersionScheme 44 */ 45 public class PatternExclusionsFilter implements TransformableFilter 46 { 47 48 private final Collection<String> excludes; 49 50 /** 51 * The default constructor specifying a collection of pattern based keys which must be excluded. 52 * 53 * @param excludes the excludes, must not be {@code null} 54 */ 55 public PatternExclusionsFilter( Collection<String> excludes ) 56 { 57 this.excludes = Collections.unmodifiableCollection( excludes ); 58 } 59 60 /** 61 * Get the excludes 62 * 63 * @return the excluded keys, never {@code null} 64 */ 65 public final Collection<String> getExcludes() 66 { 67 return excludes; 68 } 69 70 /** 71 * {@inheritDoc} 72 * 73 * Transform this filter to a tool specific implementation 74 */ 75 @Override 76 public <T> T transform( FilterTransformer<T> transformer ) 77 { 78 return transformer.transform( this ); 79 } 80 }
