所有已实现的接口:

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

直接已知子类:

BindingAwareConcurrentModel

public class ConcurrentModel
extends ConcurrentHashMap<String,Object>
implements Model

Implementation of the Model interface based on a ConcurrentHashMap for use in concurrent scenarios.

Exposed to handler methods by Spring WebFlux, typically via a declaration of the Model interface. There is typically no need to create it within user code. If necessary a handler method can return a regular java.util.Map, likely a java.util.ConcurrentMap, for a pre-determined model.

构造器详细资料

ConcurrentModel

public ConcurrentModel()

Construct a new, empty ConcurrentModel.

ConcurrentModel

public ConcurrentModel(String attributeName,
                       Object attributeValue)

Construct a new ModelMap containing the supplied attribute under the supplied name.

另请参阅:

addAttribute(String, Object)

ConcurrentModel

public ConcurrentModel(Object attributeValue)

Construct a new ModelMap containing the supplied attribute. Uses attribute name generation to generate the key for the supplied model object.

另请参阅:

addAttribute(Object)

方法详细资料

put

public Object put(String key,
                  Object value)

指定者:

put 在接口中 Map<String,Object>

覆盖:

put 在类中 ConcurrentHashMap<String,Object>

putAll

public void putAll(Map<? extends String,?> map)

指定者:

putAll 在接口中 Map<String,Object>

覆盖:

putAll 在类中 ConcurrentHashMap<String,Object>

addAttribute

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

Add the supplied attribute under the supplied name.

指定者:

addAttribute 在接口中 Model

参数:

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

attributeValue - the model attribute value (ignored if null, just removing an existing entry if any)

addAttribute

public ConcurrentModel addAttribute(Object attributeValue)

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

参数:

attributeValue - the model attribute value (never null)

addAllAttributes

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

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

另请参阅:

addAttribute(Object)

addAllAttributes

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

Copy all attributes in the supplied Map into this Map.

指定者:

addAllAttributes 在接口中 Model

另请参阅:

addAttribute(String, Object)

mergeAttributes

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

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

containsAttribute

public boolean containsAttribute(String attributeName)

Does this model contain an attribute of the given name?

指定者:

containsAttribute 在接口中 Model

参数:

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

返回:

whether this model contains a corresponding attribute

asMap

public Map<String,Object> asMap()

从接口复制的说明: Model

Return the current set of model attributes as a Map.

指定者:

asMap 在接口中 Model
