HibernateDataSource (Smart GWT EE Server API 5.0p (2021-05-26))

com.isomorphic.datasource.DataSource
- com.isomorphic.datasource.BasicDataSource
- - com.isomorphic.hibernate.HibernateDataSource

All Implemented Interfaces:

IToJSON, RPCManagerCompletionCallback
```
public class HibernateDataSource
extends BasicDataSource
implements RPCManagerCompletionCallback
```
A DataSource implementation for the Hibernate ORM system. SmartClient Server can integrate with Hibernate's ORM facilities, making use of new or existing bean mappings, or it can drive Hibernate as a pure storage layer in "beanless" mode. In this latter mode, SmartClient programs can connect to a Hibernate data store for all four CRUD operations, with zero server-side code or Hibernate configuration.
See the client reference documentation for details of configuring and using Hibernate DataSources - search for "hibernateIntegration". For a wider general discussion of data integration options with SmartClient Server, search the client documentation for "serverDataIntegration"

- Field Detail
  - ESCAPE_CHARACTER
```
public static final java.lang.Character ESCAPE_CHARACTER
```
    Holds character ('~') used to escape wild cards in 'like' clause. Avoid using backslash '\' or dollar sign '$' because it is often used in databases as DB escape or wild card characters.
  - relatedUpdates
```
protected java.util.List relatedUpdates
```
    Holds list of generated related updates. Usage: set this field to empty list before executing setProperties(); subsequent calls to setRelationFieldValue() will add DSResponse objects for every change in related data sources.
  - generateRelatedUpdates
```
protected java.lang.Boolean generateRelatedUpdates
```
    Holds value should related updates be generated. (Re)initialized on every execute() call. true - related updates will be generated; false - related updates will not be generated; null - related updates will be generated only for "add" and "update" operations, related updates will not be generated for "remove" operation.
  - additionalFields
```
protected java.util.Map additionalFields
```
    Holds list of additional fields requested by specific DSRequest.
- Method Detail
  - getFieldNames
```
public java.util.List getFieldNames(boolean dropIgnored)
```
    Returns combined list of data source configured and request configured field names.
    
    Parameters:
    dropIgnored - boolean true - ignored fields are dropped; false - ignored fields are included;
    
    Returns:
    List field names.
  - getField
```
public DSField getField(java.lang.String fieldName)
```
    Returns DSField by specified name. First checks data source configured fields. Checks request configured fields if it is not found within data source configured fields. Returns null if fieldName parameter is null or field is not found.
    
    Returns:
    DSField field.
  - escapeValueForFilter
```
public static java.lang.String escapeValueForFilter(java.lang.Object value,
                                    char escapeChar)
```
    Escapes characters "_" and "%" with specified character in value object. Specified escape character is escped (doubled) as well. Empty string is returned if value object is null.
    
    Parameters:
    value - Object Value which should be escaped.
    escapeChar - char ecape character.
    
    Returns:
    String Escaped string value.
  - startTransaction
```
public static org.hibernate.Transaction startTransaction()
                                                  throws java.lang.Exception
```
    Deprecated. As of SmartClient 8.0. Use HibernateTransaction.startTransaction(RPCManager) instead
    
    Start a new transaction. The transaction ends when either HibernateDataSource.commitTransaction() or HibernateDataSource.rollbackTransaction() is called for the transaction.
    
    Throws:
    
    java.lang.Exception
  - rollbackTransaction
```
public static void rollbackTransaction(org.hibernate.Transaction trx)
                                throws java.lang.Exception
```
    Deprecated. As of SmartClient 8.0. Use HibernateTransaction.rollbackTransaction(Transaction) instead
    
    Rollback and clean up the supplied transaction
    
    Throws:
    
    java.lang.Exception - if problems were found rolling back the transaction
  - commitTransaction
```
public static void commitTransaction(org.hibernate.Transaction trx)
                              throws java.lang.Exception
```
    Deprecated. As of SmartClient 8.0. Use HibernateTransaction.commitTransaction(Transaction) instead
    
    Commit and clean up the supplied transaction.
    
    Throws:
    
    java.lang.Exception - if problems were found committing the transaction
