Class HasChildFilter

public class HasChildFilter extends Object implements NodeFilter

This class accepts all tags that have a child acceptable to the filter. It can be set to operate recursively, that is perform a scan down through the node heirarchy in a breadth first traversal looking for any descendant that matches the predicate filter (which stops the search).

Field Summary
protected NodeFilter	mChildFilter The filter to apply to children.
protected boolean	mRecursive Performs a recursive search down the node heirarchy if `true`.

Constructor Summary
	HasChildFilter() Creates a new instance of a HasChildFilter.
	HasChildFilter(NodeFilter filter) Creates a new instance of HasChildFilter that accepts nodes with a direct child acceptable to the filter.
	HasChildFilter(NodeFilter filter, boolean recursive) Creates a new instance of HasChildFilter that accepts nodes with a child acceptable to the filter.

Method Summary
boolean	accept(Node node) Accept tags with children acceptable to the filter.
NodeFilter	getChildFilter() Get the filter used by this HasParentFilter.
boolean	getRecursive() Get the recusion setting for the filter.
void	setChildFilter(NodeFilter filter) Set the filter for this HasParentFilter.
void	setRecursive(boolean recursive) Sets whether the filter is recursive or not.

Field Detail

mChildFilter

protected NodeFilter mChildFilter

The filter to apply to children.

mRecursive

protected boolean mRecursive

Performs a recursive search down the node heirarchy if true.

Constructor Detail

HasChildFilter

public HasChildFilter()

Creates a new instance of a HasChildFilter. With no child filter, this would always return false from HasChildFilter.

HasChildFilter

public HasChildFilter(NodeFilter filter)

Creates a new instance of HasChildFilter that accepts nodes with a direct child acceptable to the filter.

Parameters: filter The filter to apply to the children.

HasChildFilter

public HasChildFilter(NodeFilter filter, boolean recursive)

Creates a new instance of HasChildFilter that accepts nodes with a child acceptable to the filter. Of necessity, this applies only to composite tags, i.e. those that can contain other nodes, for example <HTML></HTML>.

Parameters: filter The filter to apply to children. recursive If true, any enclosed node acceptable to the given filter causes the node being tested to be accepted (i.e. a recursive scan through the child nodes down the node heirarchy is performed).
