## Interface TransactionSupport

- All Superinterfaces:
    java.io.Serializable

      public interface TransactionSupport
      extends java.io.Serializable

  This interface may be optionally implemented by a `ManagedConnectionFactory` to provide its level of transaction support at runtime.

  When a `ManagedConnectionFactory` implements this interface, the application server uses the `TransactionSupportLevel` returned by getTransactionSupport() method and not the value specified in the resource adapter deployment descriptor or deployer configuration
