Interface DynaTag
- All Superinterfaces:
- Tag
- All Known Implementing Classes:
- DynaTagSupport
- public interface DynaTag
- extends Tag
DynaTag
represents a Jelly custom tag which
can take its attributes dynamically and store them in some data structure.
Typically a DynaTag may use either a Map or a DynaBean to implement itself
which avoids writing explicit getter and setter methods for each possible attribute.
This kind of tag can be extremely useful when making HTML-like tags which
generally output all the attributes which are used in the markup, except
one or two special attributes are used, all others pass through.
