构造器详细资料

InstanceFilter

public InstanceFilter(@Nullable
                      Collection<? extends T> includes,
                      @Nullable
                      Collection<? extends T> excludes,
                      boolean matchIfEmpty)

Create a new instance based on includes/excludes collections.

A particular element will match if it "matches" the one of the element in the includes list and does not match one of the element in the excludes list.

Subclasses may redefine what matching means. By default, an element match with another if it is equals according to Object.equals(Object)

If both collections are empty, matchIfEmpty defines if an element matches or not.

参数:

includes - the collection of includes

excludes - the collection of excludes

matchIfEmpty - the matching result if both the includes and the excludes collections are empty

方法详细资料

match

public boolean match(T instance)

Determine if the specified {code instance} matches this filter.

match

protected boolean match(T instance,
                        T candidate)

Determine if the specified instance is equal to the specified candidate.

参数:

instance - the instance to handle

candidate - a candidate defined by this filter

返回:

true if the instance matches the candidate

match

protected boolean match(T instance,
                        Collection<? extends T> candidates)

Determine if the specified instance matches one of the candidates.

If the candidates collection is null, returns false.

参数:

instance - the instance to check

candidates - a list of candidates

返回:

true if the instance match or the candidates collection is null

toString

public String toString()
