NVelocity.Util.Introspection
Class IntrospectorBase

This basic function of this class is to return a Method object for a particular class given the name of a method and the parameters to the method in the form of an Object[] The first time the Introspector sees a class it creates a class method map for the class in question. Basically the class method map is a Hastable where Method objects are keyed by a concatenation of the method name and the names of classes that make up the parameters. For example, a method with the following signature: public void method(String a, StringBuffer b) would be mapped by the key: "method" + "java.lang.String" + "java.lang.StringBuffer" This mapping is performed for all the methods in a class and stored for

cachedClassNames

protected internal System.Collections.IList cachedClassNames

Holds the qualified class names for the classes we hold in the classMethodMaps hash

classMethodMaps

protected internal System.Collections.Hashtable classMethodMaps

Holds the method maps for the classes we know about, keyed by Class object.

IntrospectorBase

public IntrospectorBase()

Initializes a new instance of the IntrospectorBase class.

clearCache

protected internal void clearCache()

Clears the classmap and classname caches

createClassMap

protected internal NVelocity.Util.Introspection.ClassMap createClassMap(System.Type c)

Creates a class map for specific class and registers it in the cache. Also adds the qualified name to the name->class map for later Classloader change detection.
