AbstractFilter()

方法概要

限定符和类型	方法和说明
Filter<T>	and(Filter<?> filter) Creates an ANDing filter.
java.util.List<T>	filter(java.util.List<?> content) Filter the input list keeping only the items that match the Filter.
boolean	matches(java.lang.Object content) Check to see if the object matches a predefined set of rules.
Filter<?>	negate() Creates an 'inverse' filter
Filter<? extends Content>	or(Filter<?> filter) Creates an ORing filter
<R> Filter<R>	refine(Filter<R> filter) This is similar to the and(Filter) method except the generic type is different.

构造器详细资料

AbstractFilter

public AbstractFilter()

方法详细资料

matches

public final boolean matches(java.lang.Object content)

从接口复制的说明: Filter

Check to see if the object matches a predefined set of rules.

指定者:

matches 在接口中 Filter<T>

参数:

content - The object to verify.

返回:

true if the object matches a predfined set of rules.

filter

public java.util.List<T> filter(java.util.List<?> content)

从接口复制的说明: Filter

Filter the input list keeping only the items that match the Filter.

指定者:

filter 在接口中 Filter<T>

参数:

content - The content to filter.

返回:

a new read-only RandomAccess list of the filtered input content.

negate

public final Filter<?> negate()

从接口复制的说明: Filter

Creates an 'inverse' filter

指定者:

negate 在接口中 Filter<T>

返回:

a Filter that returns all content except what this Filter instance would.

or

public final Filter<? extends Content> or(Filter<?> filter)

从接口复制的说明: Filter

Creates an ORing filter

指定者:

or 在接口中 Filter<T>

参数:

filter - a second Filter to OR with.

返回:

a new Filter instance that returns the 'union' of this filter and the specified filter.

and

public final Filter<T> and(Filter<?> filter)

从接口复制的说明: Filter

Creates an ANDing filter. The generic type of the result is the same as this Filter.

指定者:

and 在接口中 Filter<T>

参数:

filter - a second Filter to AND with.

返回:

a new Filter instance that returns the 'intersection' of this filter and the specified filter.

refine

public <R> Filter<R> refine(Filter<R> filter)

从接口复制的说明: Filter

This is similar to the and(Filter) method except the generic type is different.

指定者:

refine 在接口中 Filter<T>

类型参数:

R - The Generic type of the returned data is taken from the input instance.

参数:

filter - The filter to refine our results with.

返回:

A Filter that requires content to both match our instance and the refining instance, but the generic type of the retuned data is based on the refining instance, not this instance.
