java.util.Iterator |
getIterator(java.lang.Object obj,
Info i)
To support iteratives - #foreach(). |
VelMethod |
getMethod(java.lang.Object obj,
java.lang.String methodName,
java.lang.Object[] args,
Info i)
Returns a general method, corresponding to $foo.bar( $woogie ). |
VelPropertyGet |
getPropertyGet(java.lang.Object obj,
java.lang.String identifier,
Info i)
Property getter - returns VelPropertyGet appropos for #set($foo = $bar.woogie). |
VelPropertySet |
getPropertySet(java.lang.Object obj,
java.lang.String identifier,
java.lang.Object arg,
Info i)
Property setter - returns VelPropertySet appropos for #set($foo.bar = "geir"). |
void |
init()
init - does nothing - we need to have setRuntimeLogger called before getting our introspector, as the default vel introspector depends upon it. |
void |
setRuntimeLogger(org.apache.commons.logging.Log runtimeLogger)
Sets the runtime logger - this must be called before anything else besides init() as to get the logger. |
