JPA Enum

FlushModeType

java.lang.Object
  ∟ java.lang.Enum<javax.persistence.FlushModeType>
    ∟ javax.persistence.FlushModeType
Flush mode setting.

When queries are executed within a transaction, if FlushModeType.AUTO is set on the Query or javax.persistence.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 Query or 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.

If 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 or the persistence context is not joined to the current transaction, the persistence provider must not flush to the database.

JPA 1.0

Enum Constants

AUTO

Public Static Enum Methods:

FlushModeType[] 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 (FlushModeType c : FlushModeType.values())
        System.out.println(c);
Return:
an array containing the constants of this enum type, in the order they are declared
FlushModeType 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.
Return:
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
