Class ImageComponentTagHandler

java.lang.Object

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

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

All Implemented Interfaces:

HTMLContentProvider, PageComponentProvider, TagHandler

public class ImageComponentTagHandler
extends AbstractTagHandler

The image component tag handler is used to translate the image component div(or an equivalent markup) into a CQ image component.

This tag handler is registered against the markup of type invalid input: '<' div|span|img data-cq-component="image" > (Read as a div, span, img tag with the attribute data-cq-component equal to "image"). 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.

Method Details

beginHandling

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

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

Overrides:

beginHandling in class AbstractTagHandler

Parameters:

uri -

localName -

qName -

atts -

Throws:

DesignImportException

startElement

public void startElement(String uri,
 String localName,
 String qName,
 Attributes atts)
                  throws DesignImportException

Description copied from interface: TagHandler

Callback to signal the encounter of a tag start.

Once a tag handler begins handling, it receives the start tag events for all the nested tags within the purview of the tag this tag handler is registered against.

Specified by:

startElement in interface TagHandler

Overrides:

startElement in class AbstractTagHandler

Parameters:

uri -

localName -

qName -

atts -

Throws:

DesignImportException

characters

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

Description copied from interface: TagHandler

Callback to signal the encounter of character content within tags.

Specified by:

characters in interface TagHandler

Overrides:

characters in class AbstractTagHandler

Parameters:

ch -

start -

length -

Throws:

DesignImportException

endElement

public void endElement(String uri,
 String localName,
 String qName)
                throws DesignImportException

Description copied from interface: TagHandler

Callback to signal the encounter of a tag end.

Specified by:

endElement in interface TagHandler

Overrides:

endElement in class AbstractTagHandler

Parameters:

uri -

localName -

qName -

Throws:

DesignImportException

endHandling

public void endHandling(String uri,
 String localName,
 String qName)
                 throws DesignImportException

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.

Specified by:

endHandling in interface TagHandler

Overrides:

endHandling in class AbstractTagHandler

Parameters:

uri -

localName -

qName -

Throws:

DesignImportException

supportsContent

Description copied from interface: HTMLContentProvider

Indicates whether the passed HTMLContentType is supported or not

Specified by:

Parameters:

htmlContentType -

Description copied from interface: HTMLContentProvider

Specified by:
