Method Details

getInstance

public static ClassScanner getInstance(ScannerType... scannerType)

scanner

public void scanner(String... packetPrefix)

addParam

public <T> ClassScanner addParam(ArgumentKey<T> argKey,
 T obj)

添加一些参数给applicationContext

Type Parameters:

T -

Parameters:

argKey -

obj -

Returns:

getSubTypesOf

public <T> Set<Class<? extends T>> getSubTypesOf(Class<T> type)

Description copied from interface: IApplicationContext

gets all sub types in hierarchy of a given type

depends on SubTypesScanner configured

Specified by:

getSubTypesOf in interface IApplicationContext

getTypesAnnotatedWith

public Set<Class<?>> getTypesAnnotatedWith(Class<? extends Annotation> annotation)

Description copied from interface: IApplicationContext

get types annotated with a given annotation, both classes and annotations

Inherited is not honored by default.

when honoring @Inherited, meta-annotation should only effect annotated super classes and its sub types

Note that this (@Inherited) meta-annotation type has no effect if the annotated type is used for anything other then a class. Also, this meta-annotation causes annotations to be inherited only from superclasses; annotations on implemented interfaces have no effect.

depends on TypeAnnotationsScanner and SubTypesScanner configured

Specified by:

getTypesAnnotatedWith in interface IApplicationContext

getFieldsAnnotatedWith

public Set<Field> getFieldsAnnotatedWith(Class<? extends Annotation> annotation)

Description copied from interface: IApplicationContext

get all fields annotated with a given annotation

depends on FieldAnnotationsScanner configured

Specified by:

getFieldsAnnotatedWith in interface IApplicationContext

getMethodsAnnotatedWith

public Set<Method> getMethodsAnnotatedWith(Class<? extends Annotation> annotation)

Description copied from interface: IApplicationContext

get all methods annotated with a given annotation

depends on MethodAnnotationsScanner configured

Specified by:

getMethodsAnnotatedWith in interface IApplicationContext

isPrepare

public boolean isPrepare(ScannerType scannerType)

Description copied from interface: IApplicationContext

是否有扫描 scannerType

Specified by:

isPrepare in interface IApplicationContext

Returns:

getInstanceOfClass

public Object getInstanceOfClass(Class clazz,
 Object... params)

Description copied from interface: IApplicationContext

返回class的对象 可以是自身持有对象的单例 没有就new 一个.

Specified by:

getInstanceOfClass in interface IApplicationContext

Returns:
