类 IncludeExcludeSet<T,P>

java.lang.Object

com.jn.langx.util.collection.exclusion.IncludeExcludeSet<T,P>

类型参数:

T - The type of element of the set (often a pattern)

P - The type of the instance passed to the predicate

所有已实现的接口:

Predicate<P>

public class IncludeExcludeSet<T,P>
extends Object
implements Predicate<P>

Utility class to maintain a set of inclusions and exclusions.

Maintains a set of included and excluded elements. The method test(Object) will return true IFF the passed object is not in the excluded set AND ( either the included set is empty OR the object is in the included set)

The type of the underlying Set used may be passed into the constructor, so special sets like Servlet PathMap may be used.

IncludeExcludeSet

public IncludeExcludeSet()

Default constructor over HashSet

IncludeExcludeSet

public IncludeExcludeSet(Class<SET> setClass)

Construct an IncludeExclude.

类型参数:

SET - The type of a set to use as the backing store

参数:

setClass - The type of Set to using internally to hold patterns. Two instances will be created. one for include patterns and one for exclude patters. If the class is also a Predicate, then it is also used as the item test for the set, otherwise a IncludeExcludeSet.SetContainsPredicate instance is created.

IncludeExcludeSet

public IncludeExcludeSet(Set<T> includeSet,
                         Predicate<P> includePredicate,
                         Set<T> excludeSet,
                         Predicate<P> excludePredicate)

Construct an IncludeExclude

类型参数:

SET - The type of a set to use as the backing store

参数:

includeSet - the Set of items that represent the included space

includePredicate - the Predicate for included item testing (null for simple Set.contains(Object) test)

excludeSet - the Set of items that represent the excluded space

excludePredicate - the Predicate for excluded item testing (null for simple Set.contains(Object) test)
