 javax.servlet.jsp.tagext.VariableInfo
| VariableInfo | | public class VariableInfo (Code) | | TagExtraInfo classes generate VariableInfo objects to create
runtime variables available to the tags.
For example, a NESTED variable could be used like:
<mytag:loop name='i' min='0' max='10'>
Iter: <%= i %>
</mytag:loop>
|
| Field Summary | |
| public static int | AT_BEGIN
Constant for variables initialized at the beginning of a tag. | | public static int | AT_END
Constant for variables initialized at the end of a tag. | | public static int | NESTED
Constant for nested scope. |
| Constructor Summary | |
| public | VariableInfo(String varName, String className, boolean declare, int scope)
Creates information for a variable. |
| AT_BEGIN | | public static int AT_BEGIN(Code) | | Constant for variables initialized at the beginning of a tag.
These variables are initialized after doStartTag()
int _tmp = tag1.doStartTag();
int foo = Integer.intValue(pageContext.getAttribute("foo"));
if (_tmp == EVAL_BODY_INCLUDE) {
...
}
|
| AT_END | | public static int AT_END(Code) | | Constant for variables initialized at the end of a tag.
These variables are initialized after doEndTag()
int _tmp = tag1.doStartTag();
if (_tmp == EVAL_BODY_INCLUDE) {
...
}
tag1.doEndTag();
int foo = Integer.intValue(pageContext.getAttribute("foo"));
|
| NESTED | | public static int NESTED(Code) | | Constant for nested scope. A nested variable is only alive
inside a tag's body:
tag1.doInitBody();
do {
int foo = Integer.intValue(pageContext.getAttribute("foo"));
...
} while (tag1.doAfterBody() == EVAL_BODY_TAG)
|
| VariableInfo | | public VariableInfo(String varName, String className, boolean declare, int scope)(Code) | | Creates information for a variable. Generally called from a
TagExtraInfo class.
Parameters:
varName - name of the variable
Parameters:
className - the java classname of the variable
Parameters:
declare - true if the variable should be declared
Parameters:
scope - the scope of the variable |
| getClassName | | public String getClassName()(Code) | | Returns the variable's Java class.
|
| getDeclare | | public boolean getDeclare()(Code) | | True if the variable should be declared. If false, the JSP engine
assumes the variable is already declared and just assigns the value.
|
| getScope | | public int getScope()(Code) | | Returns the variable's scope.
- AT_BEGIN - available as soon as the tag starts
- NESTED - only available in the tag body
- AT_END - only available after the tag ends.
|
| getVarName | | public String getVarName()(Code) | | Returns the variable name.
