Class EISPlatform

java.lang.Object
  org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform
      org.eclipse.persistence.eis.EISPlatform

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, org.eclipse.persistence.internal.databaseaccess.Platform

Direct Known Subclasses:

JMSPlatform, XMLFilePlatform

public class EISPlatform
extends org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

An EISPlatform defines any EIS adapter specific behavior. This may include:

• Instantiation of the adapter InteractionSpec
• Conversion from an adapter custom Record
• Perform platform specific record access
• Provide XML DOM record conversion
• Provide sequence support

EISPlatform also supports behavior for specifying the record types supported and automatic data-conversion to strings.

Although use of the generic EISPlatform may be sufficient, some adapters may require that a specific platform be defined.
