 org.apache.jasper.runtime.JspRuntimeLibrary
| JspRuntimeLibrary | | public class JspRuntimeLibrary (Code) | | Bunch of util methods that are used by code generated for useBean,
getProperty and setProperty.
The __begin, __end stuff is there so that the JSP engine can
actually parse this file and inline them if people don't want
runtime dependencies on this class. However, I'm not sure if that
works so well right now. It got forgotten at some point. -akv

|
| URLEncode | | public static String URLEncode(String s, String enc)(Code) | | URL encodes a string, based on the supplied character encoding.
This performs the same function as java.next.URLEncode.encode
in J2SDK1.4, and should be removed if the only platform supported
is 1.4 or higher.
Parameters:
s - The String to be URL encoded.
Parameters:
enc - The character encoding The URL encoded String |
| coerceToBoolean | | public static boolean coerceToBoolean(String s)(Code) | | |
| coerceToDouble | | public static double coerceToDouble(String s)(Code) | | |
| coerceToFloat | | public static float coerceToFloat(String s)(Code) | | |
| coerceToShort | | public static short coerceToShort(String s)(Code) | | |
| createTypedArray | | public static void createTypedArray(String propertyName, Object bean, Method method, String[] values, Class t, Class propertyEditorClass) throws JasperException(Code) | | Create a typed array.
This is a special case where params are passed through
the request and the property is indexed.
|
| decode | | public static String decode(String encoded)(Code) | | Decode an URL formatted string.
Parameters:
encoded - The string to decode. The decoded string. |
| escapeQueryString | | public static String escapeQueryString(String unescString)(Code) | | Escape special shell characters.
Parameters:
unescString - The string to shell-escape The escaped shell string. |
| getContextRelativePath | | public static String getContextRelativePath(ServletRequest request, String relativePath)(Code) | | Convert a possibly relative resource path into a context-relative
resource path that starts with a '/'.
Parameters:
request - The servlet request we are processing
Parameters:
relativePath - The possibly relative resource path |
| getThrowable | | public static Throwable getThrowable(ServletRequest request)(Code) | | Returns the value of the javax.servlet.error.exception request
attribute value, if present, otherwise the value of the
javax.servlet.jsp.jspException request attribute value.
This method is called at the beginning of the generated servlet code
for a JSP error page, when the "exception" implicit scripting language
variable is initialized.

| handleSetPropertyExpression | | public static void handleSetPropertyExpression(Object bean, String prop, String expression, PageContext pageContext, ProtectedFunctionMapper functionMapper) throws JasperException(Code) | | Use proprietaryEvaluate
public static void handleSetPropertyExpression(Object bean,
String prop, String expression, PageContext pageContext,
VariableResolver variableResolver, FunctionMapper functionMapper )
throws JasperException
{
try {
Method method = getWriteMethod(bean.getClass(), prop);
method.invoke(bean, new Object[] {
pageContext.getExpressionEvaluator().evaluate(
expression,
method.getParameterTypes()[0],
variableResolver,
functionMapper,
null )
});
} catch (Exception ex) {
throw new JasperException(ex);
}
}
|
| include | | public static void include(ServletRequest request, ServletResponse response, String relativePath, JspWriter out, boolean flush) throws IOException, ServletException(Code) | | Perform a RequestDispatcher.include() operation, with optional flushing
of the response beforehand.
Parameters:
request - The servlet request we are processing
Parameters:
response - The servlet response we are processing
Parameters:
relativePath - The relative path of the resource to be included
Parameters:
out - The Writer to whom we are currently writing
Parameters:
flush - Should we flush before the include is processed?
exception:
IOException - if thrown by the included servlet
exception:
ServletException - if thrown by the included servlet |
