NVelocity.Runtime
Interface RuntimeServices

Interface for internal runtime services that are needed by the various components w/in Velocity. This was taken from the old Runtime singleton, and anything not necessary was removed. Currently implemented by RuntimeInstance.

Method Summary
void addProperty(string key, object value_Renamed)
         Allow an external system to set an ExtendedProperties object to use. This is useful where the external system also uses the ExtendedProperties class and the velocity configuration is a subset of parent application's configuration. This is the case with Turbine. * Add a property to the configuration. If it already exists then the value stated here will be added to the configuration entry. For example, if * resource.loader = file * is already present in the configuration and you * addProperty("resource.loader", "classpath") * Then you will end up with a Vector like the following: * ["file", "classpath"] *
bool addVelocimacro(string name, string macro, string[] argArray, string sourceTemplate)
         Adds a new Velocimacro. Usually called by Macro only while parsing. *
void clearProperty(string key)
         Clear the values pertaining to a particular property. *
void debug(object message)
         Log a debug message. *
bool dumpVMNamespace(string namespace_Renamed)
         tells the vmFactory to dump the specified namespace. This is to support clearing the VM list when in inline-VM-local-scope mode
void error(object message)
         Log an error message. *
object getApplicationAttribute(object key)
         Return the velocity runtime configuration object. *
bool getBoolean(string key, bool def)
         Boolean property accessor method to hide the configuration implementation.

         Returns a static content resource from the resource manager. *
NVelocity.Runtime.Resource.ContentResource getContent(string name)

int getInt(string key, int defaultValue)
         Int property accessor method to hide the configuration implementation. *
int getInt(string key)
         Int property accessor method to hide the configuration implementation. *
string getLoaderNameForResource(string resourceName)
         Determines is a template exists, and returns name of the loader that provides it. This is a slightly less hokey way to support the Velocity.templateExists() utility method, which was broken when per-template encoding was introduced. We can revisit this. *
object getProperty(string key)
         Allows an external caller to get a property. The calling routine is required to know the type, as this routine will return an Object, as that is what properties can be. *

         String property accessor method with default to hide the configuration implementation.

         Returns a
Template
from the resource manager *
NVelocity.Template getTemplate(string name)
         Returns a

ExtendedProperties - configuration
String - key
String - value
