Method Detail

setClassFilter

public static void setClassFilter(ClassAliases.ClassFilter filter)

getClassFilter

public static ClassAliases.ClassFilter getClassFilter()

isClassValid

public static boolean isClassValid(java.lang.Class<?> cls)

isClassValid

public static <C> boolean isClassValid(java.lang.Object comp)

Checks a component to see if its class is valid according to any class filter which has been set. If the component is a ParameterizedClass, then its parameter type is checked as well.

addPackageAliases

public static void addPackageAliases(java.lang.String pkgName,
                                     java.lang.String regex,
                                     java.lang.Class<?> T)

Searches for the subclasses of T within a specified package whose full name match the specified regular expression, and adds them to the alias table, using their simple names as a key.

addAlias

public static boolean addAlias(java.lang.String alias,
                               java.lang.Class<?> cls)

addAlias

public static boolean addAlias(java.lang.String alias,
                               java.lang.String className)

getAlias

public static java.lang.String getAlias(java.lang.Class<?> cls)

getAliasOrName

public static java.lang.String getAliasOrName(java.lang.Class<?> cls)

resolveClass

public static java.lang.Class<?> resolveClass(java.lang.String nameOrAlias)

Try to find the class associated with a specified name or alias. The input string is first checked to see if it corresponds to a class alias or a valid class name. If not, the method attempts to find a valid class name by appending the input string to a list of predefined package names. If a valid class is found by any of these means the associated class is returned.

Parameters:

nameOrAlias - string used to identity class

Returns:

valid class, or null if no class was found
