Public Methods

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

Copy all attributes in the supplied Map into this Map.

public ExtendedModelMap addAllAttributes (Collection<?> attributeValues)

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

public ExtendedModelMap 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.

Parameters
attributeValue the model attribute value (never null)

public ExtendedModelMap addAttribute (String attributeName, Object attributeValue)

Add the supplied attribute under the supplied name.

Parameters
attributeName the name of the model attribute (never null)
attributeValue the model attribute value (can be null)

public Map<String, Object> asMap ()

Return the current set of model attributes as a Map.

public ExtendedModelMap mergeAttributes (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).
