[Java] Class LayoutWriterStack

    java.lang.Object
      org.codehaus.groovy.grails.web.taglib.LayoutWriterStack

    public class LayoutWriterStack
    extends java.lang.Object

Class that can be used by "layout" tags, i.e. tags that use the different parts in their body to assemble a bigger part. Example a threeColumn tag that expects a left, center and right part in its body and places them in a table:

      <g.threeColumn>
          <g.left>left contents</g.left>
          <g.center>middle contents</g.center>
          <g.right>right contents</g.right>
      </g.threeColumn>

            LayoutWriterStack.currentWriter('left') << "<div class='left'>" << body() <<"</div>"
        }

  Executes the body closure of a tag and returns a Map with namned results that hold the content of the parts within the body. This method should only be called by tags that are part of a surrounding layout tag. Example:

        def parts = LayoutWriterStack.writeParts(body)
        out << "left part:" << parts.left << "; right part:" << parts.right << ";remainder of body:" << parts.body

  Parameters:
    `body` - the body closure of the calling "layout" tag
  Returns:
    a Map that contains the results of all the parts in the body and the body itself
