This service provides basic functionalities to bind a value to a key. It understands a cache logic, and can determine if a value is deprecated or not, following user's given information of temporal validity.

• Database: DataCache.sql
• This service relies on the DatabaseConnection library.

• Atomic types: xsd:string, xsd:boolean & xsd:int
• Complex types:
  • DataCacheException: DataCacheException.java

Operations will throw a DataCacheException fault if they encounter a problem at runtime. All keys must be initialized using an initContent call before using it.

• void initContent(xsd:string key)
  • Initialize the cache mechanism for the given key.
• xsd:string getContent(xsd:string key)
  • Extract the content of the cache for the given key.
• xsd:boolean isValid(xsd:string key, xsd:int delta)
  • Perform a validity test for a cache value. Return true is the value was stored less than delta minutes ago, false elsewhere.
• void setContent(xsd:string key, xsd:string content)
  • Put a given content to a given key inisde the cache.
