org.htmlparser.filters.XorFilter

所有已实现的接口:

java.io.Serializable, java.lang.Cloneable, NodeFilter

public class XorFilter
extends java.lang.Object
implements NodeFilter

Accepts nodes matching an odd number of its predicates filters (XOR operation). For example, where it has two filters, it accepts only if and only if one of the two filters accepts the Node, but does not accept if both filters accept the Node.

public XorFilter(NodeFilter left,
                 NodeFilter right)

Creates an XorFilter that accepts nodes acceptable to either filter, but not both.

参数:

left - One filter.

right - The other filter.

XorFilter

public XorFilter(NodeFilter[] predicates)

Creates an XorFilter that accepts nodes acceptable an odd number of the given filters.

参数:

predicates - The list of filters.

方法详细资料

getPredicates

public NodeFilter[] getPredicates()

Get the predicates used by this XorFilter.

返回:

The predicates currently in use.

setPredicates

public void setPredicates(NodeFilter[] predicates)

Set the predicates for this XorFilter.

参数:

predicates - The list of predidcates to use in accept(org.htmlparser.Node).

accept

public boolean accept(Node node)

Accept nodes that are acceptable to an odd number of its predicate filters.

指定者:

accept 在接口中 NodeFilter

参数:

node - The node to check.

返回:

true if an odd number of the predicate filters find the node is acceptable, false otherwise.
