getKeyClass

public Class getKeyClass(Class parentClass,
                         String property)

Determines the key class by looking for the value of @Key annotation for the given class. If no annotation is found, the key class is determined by using the generic parametrics. As fallback, it determines the key class by looking for the value of Key_${property} in the properties file for the given class.

指定者:

getKeyClass 在接口中 ObjectTypeDeterminer

参数:

parentClass - the Class which contains as a property the Map or Collection we are finding the key for.

property - the property of the Map or Collection for the given parent class

另请参阅:

ObjectTypeDeterminer.getKeyClass(Class, String)

getElementClass

public Class getElementClass(Class parentClass,
                             String property,
                             Object key)

Determines the element class by looking for the value of @Element annotation for the given class. If no annotation is found, the element class is determined by using the generic parametrics. As fallback, it determines the key class by looking for the value of Element_${property} in the properties file for the given class. Also looks for the deprecated Collection_${property}

指定者:

getElementClass 在接口中 ObjectTypeDeterminer

参数:

parentClass - the Class which contains as a property the Map or Collection we are finding the key for.

property - the property of the Map or Collection for the given parent class

另请参阅:

ObjectTypeDeterminer.getElementClass(Class, String, Object)

getKeyProperty

public String getKeyProperty(Class parentClass,
                             String property)

Determines the key property for a Collection by getting it from the @KeyProperty annotation. As fallback, it determines the String key property for a Collection by getting it from the conversion properties file using the KeyProperty_ prefix. KeyProperty_${property}=somePropertyOfBeansInTheSet

指定者:

getKeyProperty 在接口中 ObjectTypeDeterminer

参数:

parentClass - the Class which contains as a property the Map or Collection we are finding the key for.

property - the property of the Map or Collection for the given parent class

ObjectTypeDeterminer.getKeyProperty(Class, String)

shouldCreateIfNew

public boolean shouldCreateIfNew(Class parentClass,
                                 String property,
                                 Object target,
                                 String keyProperty,
                                 boolean isIndexAccessed)

Determines the createIfNull property for a Collection or Map by getting it from the @CreateIfNull annotation. As fallback, it determines the boolean CreateIfNull property for a Collection or Map by getting it from the conversion properties file using the CreateIfNull_ prefix. CreateIfNull_${property}=true|false

指定者:

shouldCreateIfNew 在接口中 ObjectTypeDeterminer

参数:

parentClass - the Class which contains as a property the Map or Collection we are finding the key for.

property - the property of the Map or Collection for the given parent class

target -

keyProperty -

isIndexAccessed - true, if the collection or map is accessed via index, false otherwise.

返回:

true, if the Collection or Map should be created, false otherwise.

getAnnotation

protected <T extends Annotation> T getAnnotation(Class parentClass,
                                                 String property,
                                                 Class<T> annotationClass)

Retrieves an annotation for the specified property of field, setter or getter.

类型参数:

T - the annotation type to be retrieved

参数:

parentClass - the class

property - the property

annotationClass - the annotation

返回:

the field or setter/getter annotation or null if not found
