Enum RequestConfig.ReadTransactionMode

java.lang.Object
  java.lang.Enum<RequestConfig.ReadTransactionMode>
      com.bea.dsp.RequestConfig.ReadTransactionMode

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<RequestConfig.ReadTransactionMode>

Enclosing class:

RequestConfig

public static enum RequestConfig.ReadTransactionMode
extends java.lang.Enum<RequestConfig.ReadTransactionMode>

Enumerated attribute indicating how the DSP server should handle transactions when executing read-only function or ad-hoc query. The names of these values are based on similar names for transaction handling for EJBs.

Note: This only affects the behaviour of read-only functions or queries. The DSP server will always create a transaction if necessary when executing a read/write operation such as a create, update or delete.

Enum Constant Summary

NOT_SUPPORTED
Read operations will not make use of a transaction if one is active on the client, and no transaction will be created.

REQUIRED
Read operations will make use of a transaction if one is active on the client.

SUPPORTS
Read operations will make use of a transaction if one is active on the client.

static RequestConfig.ReadTransactionMode	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static RequestConfig.ReadTransactionMode[]	values() Returns an array containing the constants of this enum type, in the order they're declared.

Enum Constant Detail

SUPPORTS

public static final RequestConfig.ReadTransactionMode SUPPORTS

Read operations will make use of a transaction if one is active on the client. If no transaction is open, however, one will not be created. This is the default setting.

REQUIRED

public static final RequestConfig.ReadTransactionMode REQUIRED

Read operations will make use of a transaction if one is active on the client. If no transaction is open on the client, one will be created on the server for the duration of the read operation.

NOT_SUPPORTED

public static final RequestConfig.ReadTransactionMode NOT_SUPPORTED

Read operations will not make use of a transaction if one is active on the client, and no transaction will be created.

Method Detail

values

public static final RequestConfig.ReadTransactionMode[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(RequestConfig.ReadTransactionMode c : RequestConfig.ReadTransactionMode.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static RequestConfig.ReadTransactionMode valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
