Method Detail

addAttribute

public ExtendedModelMap addAttribute(String attributeName,
                            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)

addAttribute

public ExtendedModelMap addAttribute(Object attributeValue)

Description copied from class: ModelMap

attributeValue - the model attribute value (never null)
