- All Implemented Interfaces:
Serializable
public class CacheEntry extends Object implements Serializable
Meta data for a value that's stored in a cache. Can be used for cache implementations that don't support both validity and attributes natively. Cache implementations are not required to use this type.Since OmniFaces 3.0 the
Object value
andMap<String, Object> attributes
have been reworked toSerializable value
andMap<String, Serializable> attributes
in order to explicitly set the expected type.- Since:
- 1.1

getValue
public Serializable getValue()
Returns the value for which this object is keeping meta data- Returns:
- The value for which meta data is kept
-
setValue
public void setValue(Serializable value)
Sets the value for which this object is keeping meta data- Parameters:
value
- The value for which meta data is kept
-
getValidTill
public Date getValidTill()
Returns the date that's the last moment in time the value obtained via getValue() is valid. After that moment, the value should not be used.- Returns:
- date indicating last moment value hold by this object is valid.
-
setValidTill
public void setValidTill(Date validTill)
Sets the date that's the last moment in time the value obtained via getValue() is valid. After that moment, the value should not be used.- Parameters:
validTill
- date indicating last moment value hold by this object is valid.- Since:
- 1.2
-
isValid
public boolean isValid()
Returns whether this entry holds a valid value. If false is returned, the value should not be used and the cache implementation should try to remove this entry and its associated value from the cache.- Returns:
- true if this entry is still valid, false otherwise.
-
getAttributes
public Map<String,Serializable> getAttributes()
Gets a map of attributes associated with this entry.Attributes are general key,value pairs, that are currently mainly used to store the result of EL expressions that appear in the rendering represented by the main value this entry represents.
