Method Detail

injectInto

public static Object injectInto(Object objectToInject,
                                Object target,
                                String property)

Explicit injection of the objectToInject into the specified property of the target. The property should be a correct OGNL expression.

Parameters:

objectToInject - The object that is injected

target - The target object

property - The OGNL expression that defines where the object will be injected, not null

Returns:

The object that was replaced by the injection

injectIntoStatic

public static Object injectIntoStatic(Object objectToInject,
                                      Class<?> targetClass,
                                      String property)

Explicit injection of the objectToInject into the specified static property of the target class. The property should be a correct OGNL expression.

Parameters:

objectToInject - The object that is injected

targetClass - The target class, not null

property - The OGNL expression that defines where the object will be injected, not null

Returns:

The object that was replaced by the injection

injectIntoByType

public static Object injectIntoByType(Object objectToInject,
                                      Type objectToInjectType,
                                      Object target,
                                      PropertyAccess propertyAccess)

Performs auto-injection by type of the objectToInject on the target object.

Parameters:

objectToInject - The object that is injected

objectToInjectType - The type of the object. This should be the type of the object or one of his super-types or implemented interfaces. This type is used for property type matching on the target object

target - The object into which the objectToInject is injected

propertyAccess - Defines if field or setter injection is used

Returns:

The object that was replaced by the injection

injectIntoStaticByType

public static Object injectIntoStaticByType(Object objectToInject,
                                            Type objectToInjectType,
                                            Class<?> targetClass,
                                            PropertyAccess propertyAccess)

Performs auto-injection by type of the objectToInject into the target class.

Parameters:

objectToInject - The object that is injected

objectToInjectType - The type of the object. This should be the type of the object or one of his super-types or implemented interfaces. This type is used for property type matching on the target class

targetClass - The class into which the objectToInject is injected

propertyAccess - Defines if field or setter injection is used

Returns:

The object that was replaced by the injection

injectIntoAnnotated

public static void injectIntoAnnotated(Object objectToInject,
                                       Object target,
                                       Class<? extends Annotation> annotation)

injectIntoAnnotatedMethods

public static void injectIntoAnnotatedMethods(Object objectToInject,
                                              Object target,
                                              Class<? extends Annotation> annotation)

injectIntoAnnotatedFields

public static void injectIntoAnnotatedFields(Object objectToInject,
                                             Object target,
                                             Class<? extends Annotation> annotation)
