Constructor Details

AndFilterWrapper

public AndFilterWrapper()
Create a wrapper over a new AndFilter.

Method Details

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.

getDescription

public String getDescription()
Get the name of the filter.
Overrides:
getDescription in interface Filter
Returns:
A descriptive name for the filter.

getIconSpec

public String getIconSpec()
Get the resource name for the icon.
Overrides:
getIconSpec in interface Filter
Returns:
The icon resource specification.

getNodeFilter

public NodeFilter getNodeFilter()
Get the underlying node filter object.
Overrides:
getNodeFilter in interface Filter
Returns:
The node filter object suitable for serialization.

getSubNodeFilters

public NodeFilter[] getSubNodeFilters()
Get the underlying node filter's subordinate filters.
Overrides:
getSubNodeFilters in interface Filter
Returns:
The node filter object's contained filters.

setNodeFilter

public void setNodeFilter(NodeFilter filter,
                          Parser context)
Assign the underlying node filter for this wrapper.
Overrides:
setNodeFilter in interface 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.

setSubNodeFilters

public void setSubNodeFilters(NodeFilter[] filters)
Assign the underlying node filter's subordinate filters.
Overrides:
setSubNodeFilters in interface 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.
Overrides:
toJavaCode in interface 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]++)
