Method Detail

addAttribute

public ExtendedModelMap addAttribute(java.lang.String attributeName,
                                     java.lang.Object attributeValue)
Description copied from class: ModelMap
Add the supplied attribute under the supplied name.

Specified by:
addAttribute in interface Model
Overrides:
addAttribute in class ModelMap
Parameters:
attributeName - the name of the model attribute (never null)
attributeValue - the model attribute value (can be null)

addAttribute

public ExtendedModelMap addAttribute(java.lang.Object attributeValue)
Description copied from class: 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.

Specified by:
addAttribute in interface Model
Overrides:
addAttribute in class ModelMap
Parameters:
attributeValue - the model attribute value (never null)

addAllAttributes

public ExtendedModelMap addAllAttributes(java.util.Collection<?> attributeValues)
Description copied from class: ModelMap
Copy all attributes in the supplied Collection into this Map, using attribute name generation for each element.

Specified by:
addAllAttributes in interface Model
Overrides:
addAllAttributes in class ModelMap
See Also:
ModelMap.addAttribute(Object)

addAllAttributes

public ExtendedModelMap addAllAttributes(java.util.Map<java.lang.String,?> attributes)
Description copied from class: ModelMap
Copy all attributes in the supplied Map into this Map.

Specified by:
addAllAttributes in interface Model
Overrides:
addAllAttributes in class ModelMap
See Also:
ModelMap.addAttribute(String, Object)

mergeAttributes

public ExtendedModelMap mergeAttributes(java.util.Map<java.lang.String,?> attributes)
Description copied from class: 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).

Specified by:
mergeAttributes in interface Model
Overrides:
mergeAttributes in class ModelMap

asMap

public java.util.Map<java.lang.String,java.lang.Object> asMap()
Description copied from interface: Model
Return the current set of model attributes as a Map.

Specified by:
