Class OracleCacheDependency

java.lang.Object

com.alachisoft.ncache.runtime.dependencies.CacheDependency

com.alachisoft.ncache.runtime.dependencies.OracleCacheDependency

All Implemented Interfaces:

java.io.Serializable

public final class OracleCacheDependency
extends CacheDependency

Establishes a relationship between an item stored in an application's Cache object and either a row in a specific Oracle database table or the results of a Oracle query. This class can not be inherited. You can add items with dependencies to your application's cache with the "Cache.Add" and Add,Insert, AddDependency methods. When you add an item to an application's "Cache" object with "OracleCacheDependency", on all ODP.NET supported versions of Oracle database, it monitors a row in a specific Oracle database table so that when that row changes, items associated with the row will be automatically removed from the Cache. This helps you avoid losing changes made to the object between the time it is created and the time it is inserted into the "Cache". "OracleCacheDependency" class supports the association of cached items with a Oracle query.

Constructor Detail

OracleCacheDependency

public OracleCacheDependency(java.lang.String connectionString,
                     java.lang.String cmdText)

Initializes a new instance of the OracleCacheDependency class, using the supplied connection string and query string. This constructor is used to create OracleCacheDependency objects that use the query-notification feature of Oracle products. Query must include the following: Fully qualified table names, including the name of the table owner. For example, to refer to a table called "customers" that is owned by the database owner, the statement must refer to "dbo.customers".

Parameters:

connectionString - connection string to be used by dependency.

cmdTextcmdText - to be used by dependency
