IDLE
public static final PGXAConnection.State IDLE
PGXAConnection
not associated with a XA-transaction. You can still callPGXAConnection.getConnection()
and use the connection outside XA.currentXid
isnull
. autoCommit istrue
on a connection by getConnection, per normal JDBC rules, though the caller can change it tofalse
and manage transactions itself using Connection.commit and rollback.
-
ACTIVE
public static final PGXAConnection.State ACTIVE
PGXAConnection.start(Xid, int)
has been called, and we're associated with an XA transaction.currentXid
is valid. autoCommit is false on a connection returned by getConnection, and should not be messed with by the caller or the XA transaction will be broken.
-
ENDED
public static final PGXAConnection.State ENDED
PGXAConnection.end(Xid, int)
has been called, but the transaction has not yet been prepared.currentXid
is still valid. You shouldn't use the connection for anything else than issuing aXAResource.commit(Xid, boolean)
or rollback.

values
public static PGXAConnection.State[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (PGXAConnection.State c : PGXAConnection.State.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static PGXAConnection.State 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 namejava.lang.NullPointerException
