Constructor Detail

HasAttributeFilterWrapper

public HasAttributeFilterWrapper()

Create a wrapper over a new HasAttributeFilter.

Method Detail

addAttributes

protected void addAttributes(Set set,
                             Node node)

Add the attribute names from the node to the set of attribute names.

Parameters:

set - The set to add to.

node - The node with attributes to add.

addAttributeValues

protected void addAttributeValues(Set set,
                                  Node node)

Add the attribute values from the node to the set of attribute values.

Parameters:

set - The set to add to.

node - The node with attributes to add.

getDescription

public String getDescription()

Get the name of the filter.

Specified by:

getDescription in class Filter

Returns:

A descriptive name for the filter.

getIconSpec

public String getIconSpec()

Get the resource name for the icon.

Specified by:

getIconSpec in class Filter

Returns:

The icon resource specification.

getNodeFilter

public NodeFilter getNodeFilter()

Get the underlying node filter object.

Specified by:

getNodeFilter in class Filter

Returns:

The node filter object suitable for serialization.

setNodeFilter

public void setNodeFilter(NodeFilter filter,
                          Parser context)

Assign the underlying node filter for this wrapper.

Specified by:

setNodeFilter in class Filter

Parameters:

filter - The filter to wrap.

context - The parser to use for conditioning this filter. Some filters need contextual information to provide to the user, i.e. for tag names or attribute names or values, so the Parser context is provided.

getSubNodeFilters

public NodeFilter[] getSubNodeFilters()

Get the underlying node filter's subordinate filters.

Specified by:

getSubNodeFilters in class Filter

Returns:

The node filter object's contained filters.

setSubNodeFilters

public void setSubNodeFilters(NodeFilter[] filters)

Assign the underlying node filter's subordinate filters.

Specified by:

setSubNodeFilters in class Filter

Parameters:

filters - The filters to insert into the underlying node filter.

toJavaCode

public String toJavaCode(StringBuffer out,
                         int[] context)

Convert this filter into Java code. Output whatever text necessary and return the variable name.

Specified by:

toJavaCode in class Filter

Parameters:

out - The output buffer.

context - Three integers as follows:

indent level - the number of spaces to insert at the beginning of each line

filter number - the next available filter number

filter array number - the next available array of filters number

Returns:

The variable name to use when referencing this filter (usually "filter" + context[1]++)

accept

public boolean accept(Node node)

Predicate to determine whether or not to keep the given node. The behaviour based on this outcome is determined by the context in which it is called. It may lead to the node being added to a list or printed out. See the calling routine for details.

Specified by:

accept in interface NodeFilter

Parameters:

node - The node to test.

Returns:

true if the node is to be kept, false if it is to be discarded.

actionPerformed

public void actionPerformed(ActionEvent event)

Invoked when an action occurs on the combo box.

Specified by:

actionPerformed in interface ActionListener

Parameters:

event - Details about the action event.

insertUpdate

public void insertUpdate(DocumentEvent e)

Handle an insert update event.

Specified by:

insertUpdate in interface DocumentListener

Parameters:

e - Details about the insert event.

removeUpdate

public void removeUpdate(DocumentEvent e)

Handle a remove update event.

Specified by:

removeUpdate in interface DocumentListener

Parameters:

e - Details about the remove event.

changedUpdate

public void changedUpdate(DocumentEvent e)

Handle a change update event.

Specified by:

changedUpdate in interface DocumentListener

Parameters:

e - Details about the change event.
