Class MetaTagHandler

java.lang.Object

com.day.cq.wcm.designimporter.parser.taghandlers.MetaTagHandler

All Implemented Interfaces:

HTMLContentProvider, TagHandler

public class MetaTagHandler
extends Object
implements TagHandler, HTMLContentProvider

This tag handler is used to parse the metadata associated with the HTML page via the meta tags.

This tag handler is registered against the markup of type < meta >. That implies this tag handler will come into action whenever the design importer framework encounters an HTML tag matching the rule this handler is defined against.

beginHandling

public void beginHandling(String uri,
                 String localName,
                 String qName,
                 Attributes atts)

Description copied from interface: TagHandler

Callback to signal the start of handling giving the tag handler a chance for running intialization routines.

TagHandlers are registered against tag+attribute combination and are invoked by the HTMLContentHandler as and when it encounters a tag matching the tag attribute combination the tag handler is registered with.

Specified by:

beginHandling in interface TagHandler

characters

public void characters(char[] ch,
              int start,
              int length)
                throws DesignImportException

Description copied from interface: TagHandler

              String qName)
                throws DesignImportException

Description copied from interface: TagHandler

endHandling

public void endHandling(String uri,

               String qName)

Description copied from interface: TagHandler

Callback to signal the end of handling giving the tag handler a chance for finalizing things.

This is arguably the last callback a tag handler receives. After this, the current tag handler is popped out from the chain and the subsequent Tika events are directed to preceding tag handlers.

Returns:

setDesignImporterContext

public void setDesignImporterContext(DesignImporterContext designImporterContext)
