Method Detail

getTypes

public static java.util.Set<java.lang.String> getTypes(Application app,
                                                       java.lang.String packageName)

Scans the application classloader to retrieve all types within a specific package.

This method is useful for some plug-ins, for example the EBean plugin will automatically detect all types within the models package.

Note that it is better to specify a very specific package to avoid expensive searches.

Parameters:

packageName - the root package to scan

Returns:

a set of types names satisfying the condition

getTypesAnnotatedWith

public static java.util.Set<java.lang.Class<?>> getTypesAnnotatedWith(Application app,
                                                                      java.lang.String packageName,
                                                                      java.lang.Class<? extends java.lang.annotation.Annotation> annotation)

Scans the application classloader to retrieve all types annotated with a specific annotation.

This method is useful for some plug-ins, for example the EBean plugin will automatically detect all types annotated with @javax.persistance.Entity.

Note that it is better to specify a very specific package to avoid expensive searches.

Parameters:

packageName - the root package to scan

annotation - annotation class

Returns:

a set of types names statifying the condition

getTypes

public static java.util.Set<java.lang.String> getTypes(Environment env,
                                                       java.lang.String packageName)

Scans the environment classloader to retrieve all types within a specific package.

This method is useful for some plug-ins, for example the EBean plugin will automatically detect all types within the models package.

Note that it is better to specify a very specific package to avoid expensive searches.

Parameters:

packageName - the root package to scan

Returns:

a set of types names satisfying the condition

getTypesAnnotatedWith

public static java.util.Set<java.lang.Class<?>> getTypesAnnotatedWith(Environment env,
                                                                      java.lang.String packageName,
                                                                      java.lang.Class<? extends java.lang.annotation.Annotation> annotation)

Scans the environment classloader to retrieve all types annotated with a specific annotation.

This method is useful for some plug-ins, for example the EBean plugin will automatically detect all types annotated with @javax.persistance.Entity.

Note that it is better to specify a very specific package to avoid expensive searches.

Parameters:

packageName - the root package to scan

annotation - annotation class

Returns:

a set of types names statifying the condition
