- Parameters:
- context- The EL context for this evaluation
- base- The base object on which the property is to be found
- property- The property whose type is to be returned
- Returns:
- the most general type that maybe used to set the provided property or nullif the resolver is read-only.
 
- 
getValueDescription copied from class:ELResolverObtain the value of the given property on the given object using the given context.- Specified by:

- property- The property whose value is to be returned
- Returns:
- the value of the provided property
 
- 
setValueDescription copied from class:ELResolverSet the value of the given property on the given object using the given context.- Specified by:
