Classes and interfaces for the definition of JavaServer Pages Tag Libraries.

Description
|
Interface Summary |
| BodyTag |
The BodyTag interface extends IterationTag by defining additional
methods that let a tag handler manipulate the content of evaluating its body. |
| IterationTag |
The IterationTag interface extends Tag by defining one additional
method that controls the reevaluation of its body. |
| Tag |
The interface of a simple tag handler that does not want to manipulate its body. |
| TryCatchFinally |
The auxiliary interface of a Tag, IterationTag or BodyTag tag
handler that wants additional hooks for managing resources. |
|
Class Summary |
| BodyContent |
An encapsulation of the evaluation of the body of an action so it is
available to a tag handler. |
| BodyTagSupport |
A base class for defining tag handlers implementing BodyTag. |
| PageData |
Translation-time information on a JSP page. |
| TagAttributeInfo |
Information on the attributes of a Tag, available at translation time. |
| TagData |
The (translation-time only) attribute/value information for a tag instance. |
| TagExtraInfo |
Optional class provided by the tag library author to describe additional
translation-time information not described in the TLD. |
| TagInfo |
Tag information for a tag in a Tag Library;
This class is instantiated from the Tag Library Descriptor file (TLD)
and is available only at translation time. |
| TagLibraryInfo |
Translation-time information associated with a taglib directive, and its
underlying TLD file. |
| TagLibraryValidator |
Translation-time validator class for a JSP page. |
| TagSupport |
A base class for defining new tag handlers implementing Tag. |
| TagVariableInfo |
Variable information for a tag in a Tag Library;
This class is instantiated from the Tag Library Descriptor file (TLD)
and is available only at translation time. |
| ValidationMessage |
A validation message from a TagLibraryValidator. |
| VariableInfo |
Information on the scripting variables that are created/modified by
a tag (at run-time). |
Package javax.servlet.jsp.tagext Description
Classes and interfaces for the definition of JavaServer Pages Tag Libraries.
The JavaServer Pages(tm) (JSP) 1.2 specification provides a portable
mechanism for the description of tag libraries.
A JSP tab library contains
- A Tag Library Descriptor
- A number of Tag handler classes defining request-time behavior
- Additional classes and resources used at runtime
- Possibly some additional classes to provide extra translation information
The JSP 1.2 specification and the reference implementation both contain
simple and moderately complex examples of actions defined using this
mechanism.
These are available at JSP's web site, at
http://java.sun.com/products/jsp.
Some readers may want to consult those to get a quick feel for how
the mechanisms work together.
