Spring Context 6.1.4 · org.springframework.validation.support.BindingAwareModelMap

Subclass of org.springframework.ui.ExtendedModelMap that automatically removes a org.springframework.validation.BindingResult object if the corresponding target attribute gets replaced through regular Map operations.

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

put	back to summary
public Object put(String key, Object value) Overrides java.util.HashMap.put. Implements java.util.Map.put. Doc from java.util.Map.put. Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map `m` is said to contain a mapping for a key `k` if and only if `m.containsKey(k)` would return `true`.) Parameters key:String key with which the specified value is to be associated value:Object value to be associated with the specified key Returns:Object the previous value associated with `key`, or `null` if there was no mapping for `key`. (A `null` return can also indicate that the map previously associated `null` with `key`, if the implementation supports `null` values.) Annotations @Override

public Object put(String key, Object value)

Overrides java.util.HashMap.put.

Implements java.util.Map.put.

Doc from java.util.Map.put.

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Parameters

key:String: key with which the specified value is to be associated
value:Object: value to be associated with the specified key

Returns:Object

the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key, if the implementation supports null values.)

public void putAll(Map<? extends String, ?> map) Overrides java.util.HashMap.putAll. Implements java.util.Map.putAll. Doc from java.util.Map.putAll. Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling `put(k, v)` on this map once for each mapping from key `k` to value `v` in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress. If the specified map has a defined encounter order, processing of its mappings generally occurs in that order. Parameters map:Map<? extends String, ?> mappings to be stored in this map Annotations @Override
