类 HasParentFilter

java.lang.Object

org.htmlparser.filters.HasParentFilter

所有已实现的接口:

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

public class HasParentFilter
extends java.lang.Object
implements NodeFilter

This class accepts all tags that have a parent acceptable to another filter. It can be set to operate recursively, that is perform a scan up the node heirarchy looking for any ancestor that matches the predicate filter. End tags are not considered to be children of any tag.

构造器详细资料

HasParentFilter

public HasParentFilter()

Creates a new instance of HasParentFilter. With no parent filter, this would always return false from accept(org.htmlparser.Node).

HasParentFilter

public HasParentFilter(NodeFilter filter)

Creates a new instance of HasParentFilter that accepts nodes with the direct parent acceptable to the filter.

参数:

filter - The filter to apply to the parent.

HasParentFilter

public HasParentFilter(NodeFilter filter,
                       boolean recursive)

Creates a new instance of HasParentFilter that accepts nodes with a parent acceptable to the filter.

参数:

filter - The filter to apply to the parent.

recursive - If true, any enclosing node acceptable to the given filter causes the node being tested to be accepted (i.e. a recursive scan through the parent nodes up the node heirarchy is performed).

方法详细资料

getParentFilter

public NodeFilter getParentFilter()

Get the filter used by this HasParentFilter.

返回:

The filter to apply to parents.

setParentFilter

public void setParentFilter(NodeFilter filter)

Set the filter for this HasParentFilter.

参数:

filter - The filter to apply to parents in accept(org.htmlparser.Node).

getRecursive

public boolean getRecursive()

Get the recusion setting for the filter.

返回:

Returns true if the filter is recursive up the node heirarchy.

setRecursive

public void setRecursive(boolean recursive)

Sets whether the filter is recursive or not.

参数:

recursive - The recursion setting for the filter.

accept

public boolean accept(Node node)

Accept tags with parent acceptable to the filter. If recursion is enabled, each parent in turn up to the topmost enclosing node is checked. Recursion only proceeds while no parent satisfies the filter.

指定者:

accept 在接口中 NodeFilter

参数:

node - The node to check.

返回:

true if the node has an acceptable parent, false otherwise.
