Enum Constant Details

LAZY

public static final StoringStrategy LAZY

Lazy storing is the default storing mode of the MicroStream engine. Referenced instances are stored only if they have not been stored yet. If a referenced instance has been stored previously it is not stored again even if it has been modified. That’s why modified objects must be stored explicitly.

EAGER

public static final StoringStrategy EAGER

In eager storing mode referenced instances are stored even if they had been stored before. Contrary to Lazy storing this will also store modified child objects at the cost of performance.

Method Details

values

public static StoringStrategy[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static StoringStrategy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
