Interface DocumentProvider

All Known Implementing Classes:
  DefaultDocumentProvider

public interface DocumentProvider

A object which can provide documents and document information.

In the case of statefull connections to DMS, this should represent a single connection to the DMS (pooling will be handled by the infrastructure).

DocumentProvider can support transaction isolation levels very similar to java.sql.Connections. If the DocumentProvider doesn't support transaction isolation levels, it should always report TRANSACTION_NONE (i.e. it shouldn't thrown an exception).

Field Summary
`static int` | `TRANSACTION_NONE` Deprecated. Isolation level for no transaction support.
`static int` | `TRANSACTION_READ_COMMITTED` Deprecated. Isolation level for dirty reads are prevented; non-repeatable reads and phantom reads can occur.
`static int` | `TRANSACTION_READ_UNCOMMITTED` Deprecated. Isolation level for dirty reads, non-repeatable reads and phantom reads can occur.
`static int` | `TRANSACTION_REPEATABLE_READ` Deprecated. Isolation level for dirty reads and non-repeatable reads are prevented; phantom reads can occur.
`static int` | `TRANSACTION_SERIALIZABLE` Deprecated. Isolation level for dirty reads, non-repeatable reads and phantom reads are prevented.

Method Summary
`void` | `close()` Deprecated. Close the provider down.
`DocumentIterator` | `findDocumentIds(Search params)` Deprecated. Return the set of String document ids of documents which match the given search parameters.
`DocumentIterator` | `findDocumentMetadata(Search params)` Deprecated. Return the set of DocumentMetadataDefs which match the given search parameters object.

Method Detail

### init

    public void init(Properties properties)
              throws DocumentException

  Deprecated.
  Initialize the DocumentProvider based upon the specified configuration properties.

  This will be called after the DocumentProvider has been instantiated.

  Parameters:
    `properties` - the configuration properties
  Throws:
    `DocumentException` - thrown on an error.

### reset

    public void reset()
               throws DocumentException

  Deprecated.
  Reset the connection internally to a fresh state.

  This might include rolling back a transaction and clearing out any internal state.

  Throws:
    `DocumentException` - thrown on an error.

### close

    public void close()
               throws DocumentException

  Deprecated.
  Close the provider down.

  This will be called before the provider is dereferenced; it should close any resources opened by init() or internally. The provider instance should not be used after this method has been invoked.

  Throws:
    `DocumentException` - thrown on an error.

### getTransactionIsolation

    public int getTransactionIsolation()
                                throws DocumentException

  Deprecated.
  Get the document provider's current transaction isolation level.

    `DocumentException`

### setTransactionIsolation

    public void setTransactionIsolation(int level)
                                 throws DocumentException

  Deprecated.
  Set the document provider's transaction isolation level.

    `DocumentException`

### findDocumentIds

    public DocumentIterator findDocumentIds(Search params)
                                     throws DocumentException
