Enum Constant Detail

READONLY_OR_USE_EXISTING

public static final GcTransactionType READONLY_OR_USE_EXISTING

use the current transaction if one exists, if not, create a new readonly tx. Note, the enclosing transaction could be readonly or readwrite, and no error will be thrown. However, no matter what, this code cannot commit or rollback...

NONE

public static final GcTransactionType NONE

even if in a current tx, do not use transactions

READONLY_NEW

public static final GcTransactionType READONLY_NEW

even if in the middle of a transaction, create a new readonly autonomous nested transaction. Code in this state cannot commit or rollback.

READ_WRITE_OR_USE_EXISTING

public static final GcTransactionType READ_WRITE_OR_USE_EXISTING

use the current transaction if one exists. If there is a current transaction, it MUST be read/write or there will be an exception. If there isnt a transaction in scope, then create a new read/write one. If you do not commit at the end, and there is a normal return (no exception), then the transaction will be committed if new, and not if reusing an existing one. If there is an exception, and the tx is new, it will be rolledback. If there is an exception and the tx is reused, the tx will not be touched, and the exception will propagate.

READ_WRITE_NEW

public static final GcTransactionType READ_WRITE_NEW

even if in the middle of a transaction, create a new read/write autonomous nested transaction. If this block is exited normally it will always commit. If exception is thrown, it will always rollback.

Method Detail

values

public static GcTransactionType[] 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 (GcTransactionType c : GcTransactionType.values())
    System.out.println(c);

Returns:

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

valueOf

public static GcTransactionType valueOf(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:

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

NullPointerException - if the argument is null

valueOfIgnoreCase

public static GcTransactionType valueOfIgnoreCase(String string)

do a case-insensitive matching

Parameters:

string -

Returns:

the enum or null or exception if not found
