Interface to a container tag. A container has the following characteristics:
The tag must be of the form <mycontainer>>...<</mycontiner>.
The tag may perform an action before its content is processed (via
doBeforeBody(TagInfo, JET2Context, JET2Writer))
If the tag is a content re-writing tag (as declared in the tag extension point), then
setBodyContent(JET2Writer) is called after
doBeforeBody(TagInfo, JET2Context, JET2Writer).
The tag may perform an action after its content is processed (via
doAfterBody(TagInfo, JET2Context, JET2Writer)).
Tag processing proceeds as follows:
Tag set*() functions are called, as described by
CustomTag.
The method
doBeforeBody(TagInfo, JET2Context, JET2Writer) is called immediately before starting processing
of the tag's content
The tags content's are processed.
If the tag is declared as a content rewriter in the tagLibaries extension point, then
setBodyContent(JET2Writer) is called.
The method
doAfterBody(TagInfo, JET2Context, JET2Writer) is called.
