mAttributeName
protected JComboBox mAttributeName
Combo box for attribute name.
mAttributeValue
protected JTextArea mAttributeValue
Value to check for.
mValued
protected JCheckBox mValued
The check box for has value.
HasAttributeFilterWrapper
public HasAttributeFilterWrapper()
Create a wrapper over a new HasAttributeFilter.
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.
- accept in interface NodeFilter
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.
event
- Details about the action event.
addAttributeValues
protected void addAttributeValues(Set set,
Node node)
Add the attribute values from the node to the set of attribute values.
set
- The set to add to.node
- The node with attributes to add.
addAttributes
protected void addAttributes(Set set,
Node node)
Add the attribute names from the node to the set of attribute names.
set
- The set to add to.node
- The node with attributes to add.
changedUpdate
public void changedUpdate(DocumentEvent e)
Handle a change update event.
e
- Details about the change event.
getDescription
public String getDescription()
Get the name of the filter.
- getDescription in interface Filter
- A descriptive name for the filter.
getIconSpec
public String getIconSpec()
Get the resource name for the icon.
- getIconSpec in interface Filter
- The icon resource specification.
getNodeFilter
public NodeFilter getNodeFilter()
Get the underlying node filter object.
- getNodeFilter in interface Filter
- The node filter object suitable for serialization.
getSubNodeFilters
public NodeFilter[] getSubNodeFilters()
Get the underlying node filter's subordinate filters.
- getSubNodeFilters in interface Filter
- The node filter object's contained filters.
insertUpdate
public void insertUpdate(DocumentEvent e)
Handle an insert update event.
e
- Details about the insert event.
removeUpdate
public void removeUpdate(DocumentEvent e)
Handle a remove update event.
e
- Details about the remove event.
setNodeFilter
public void setNodeFilter(NodeFilter filter,
Parser context)
Assign the underlying node filter for this wrapper.
- setNodeFilter in interface Filter
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.
setSubNodeFilters
public void setSubNodeFilters(NodeFilter[] filters)
Assign the underlying node filter's subordinate filters.
- setSubNodeFilters in interface Filter
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.
- toJavaCode in interface Filter
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
- The variable name to use when referencing this filter (usually "filter" + context[1]++)
