所有已实现的接口:

Model, Serializable, Cloneable, Map<String,Object>

public class ExtendedModelMap
extends ModelMap
implements Model

Subclass of ModelMap that implements the Model interface.

This is an implementation class exposed to handler methods by Spring MVC, typically via a declaration of the Model interface. There is no need to build it within user code; a plain ModelMap or even a just a regular Map with String keys will be good enough to return a user model.

ExtendedModelMap

public ExtendedModelMap()

方法详细资料

addAttribute

public ExtendedModelMap addAttribute(String attributeName,
 @Nullable
 Object attributeValue)

从类复制的说明: ModelMap

Add the supplied attribute under the supplied name.

指定者:

addAttribute 在接口中 Model

覆盖:

addAttribute 在类中 ModelMap

参数:

attributeName - the name of the model attribute (never null)

attributeValue - the model attribute value (can be null)

addAttribute

public ExtendedModelMap addAttribute(Object attributeValue)

从类复制的说明: ModelMap

Add the supplied attribute to this Map using a generated name.

Note: Empty Collections are not added to the model when using this method because we cannot correctly determine the true convention name. View code should check for null rather than for empty collections as is already done by JSTL tags.

指定者:

addAttribute 在接口中 Model

覆盖:

addAttribute 在类中 ModelMap

参数:

attributeValue - the model attribute value (never null)

addAllAttributes

public ExtendedModelMap addAllAttributes(@Nullable
 Collection<?> attributeValues)

从类复制的说明: ModelMap

Copy all attributes in the supplied Collection into this Map, using attribute name generation for each element.

指定者:

addAllAttributes 在接口中 Model

覆盖:

addAllAttributes 在类中 ModelMap

另请参阅:

• ModelMap.addAttribute(Object)

addAllAttributes

public ExtendedModelMap addAllAttributes(@Nullable
 Map<String,?> attributes)

从类复制的说明: ModelMap

Copy all attributes in the supplied Map into this Map.

指定者:

addAllAttributes 在接口中 Model

覆盖:

addAllAttributes 在类中 ModelMap

另请参阅:

• ModelMap.addAttribute(String, Object)

mergeAttributes

public ExtendedModelMap mergeAttributes(@Nullable
 Map<String,?> attributes)

从类复制的说明: ModelMap

Copy all attributes in the supplied Map into this Map, with existing objects of the same name taking precedence (i.e. not getting replaced).

指定者:

mergeAttributes 在接口中 Model

覆盖:

mergeAttributes 在类中 ModelMap

asMap

public Map<String,Object> asMap()

从接口复制的说明: Model

Convert this model to a Map

指定者:

asMap 在接口中 Model

覆盖:

asMap 在类中 ModelMap
