                          ParamValueProvider params)

Resolve bean from param value provider

Parameters:

bean - cached bean instance from last conversation in the same session. Or null if not applied

model - the name to specify the model

params - the param value provider

Returns:

the bean resolved

attribute

public Binder<T> attribute(String key,
                           Object value)

Note use this method only on new resolver instance instead of shared instance

Parameters:

key - the attribute key

value - the attribute value

Returns:

this binder instance

attributes

public Binder<T> attributes(Map<String,Object> attributes)

Note use this method only on new resolver instance instead of shared instance

Parameters:

attributes - the attributes map

Returns:

this binder instance

clearAttributes

public Binder<T> clearAttributes()

Clear all attributes on this binder

Returns:

this binder instance

attribute

protected <V> V attribute(String key)

Get attribute of this binder by key specified

Type Parameters:

V - the generic type variable of attribute value

Parameters:

key - the attribute key

Returns:

the attribute value

apply
