HasChildFilter (HTML Parser 1.6)

java.lang.Object
- org.htmlparser.filters.HasChildFilter

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, NodeFilter
```
public class HasChildFilter
extends java.lang.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 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 accept(org.htmlparser.Node).
  - 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).
- Method Detail
  - getChildFilter
```
public NodeFilter getChildFilter()
```
    Get the filter used by this HasParentFilter.
    
    Returns:
    
    The filter to apply to parents.
  - setChildFilter
```
public void setChildFilter(NodeFilter filter)
```
    Set the filter for this HasParentFilter.
    
    Parameters:
    
    filter - The filter to apply to parents in accept(org.htmlparser.Node).
  - getRecursive
```
public boolean getRecursive()
```
    Get the recusion setting for the filter.
    
    Returns:
    
    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.
    
    Parameters:
    
    recursive - The recursion setting for the filter.
  - accept
```
public boolean accept(Node node)
```
    Accept tags with children acceptable to the filter.
    
    Specified by:
    
    accept in interface NodeFilter
    
    Parameters:
    
    node - The node to check.
    
    Returns:
    
    true if the node has an acceptable child, false otherwise.
