Method Detail

getClassPath

public static java.util.List<java.lang.String> getClassPath()

Returns:

a list of paths

getFullName

public static java.lang.String getFullName(java.lang.String shortName)

Return the qualified name of a class given the unqualified class name using the internal registry.

Parameters:

shortName - basic class name

Returns:

the qualified class name

setFullName

public static void setFullName(java.lang.String shortName,
                               java.lang.String fullName)

Adds the mapping to the registry.

Parameters:

shortName - basic class name

fullName - qualified class name

getExcludedNames

public static java.util.List<java.lang.String> getExcludedNames()

Returns the strings that cause exclusion of a path to be searched for Boone classes. If an unqualified class name is found in a configuration file, the associated qualified class name is searched in the class path. If an entry in the class path contains an excluded string, then this entry is not searched.

Returns:

the list of exclusion strings

newInstance

public static java.lang.Object newInstance(java.lang.String className)

Create a new instance of the class with the given name. We first try to resolve this string against the Boone registered class list.

Note that this method uses the current thread's context class loader for unknown (unregistered) classes.

Parameters:

className - Basic (if registered) or full name of the class to instantiate.

Returns:

Null if the class wasn't found, or couldn't be instantiated.

isExcluded

public static boolean isExcluded(java.lang.String path)

Indicates if the given path contains an exclusion string. If it does, then this path is not searched for Boone classes.

Parameters:

path - a string

Returns:

true, if path contains an exclusion string
