javax.persistence.FlushModeType - JPA enum
java.lang.Object java.lang.Enum<javax.persistence.FlushModeType> javax.persistence.FlushModeType
- Implemented Interfaces:
When queries are executed within a transaction, if
FlushModeType.AUTO is set on the
TypedQuery object, or if the flush mode setting for the persistence context is
AUTO (the default) and a flush mode setting has not been specified for the
TypedQuery object, the persistence provider is responsible for ensuring that all updates to the state of all entities in the persistence context which could potentially affect the result of the query are visible to the processing of the query. The persistence provider implementation may achieve this by flushing those entities to the database or by some other means.
FlushModeType.COMMIT is set, the effect of updates made to entities in the persistence context upon queries is unspecified.
If there is no transaction active, the persistence provider must not flush to the database.

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.
name- the name of the enum constant to be returned.
- the enum constant with the specified name
java.lang.IllegalArgumentException- if this enum type has no constant with the specified name
java.lang.NullPointerException- if the argument is null
Returns an array containing the constants of this enum type.
This method may be used to iterate over the constants as follows:
for (FlushModeType c : FlushModeType.values()) System.out.println(c)
- an array containing the constants of this enum type, in the order they are declared
