Enum Constant Summary

COMPLETE
Materialized view is completely refreshed from the masters

FAST
Oracle Database performs an incremental refresh applying changes that correspond to changes in the masters since the last refresh When you specify FAST refresh at create time, Oracle Database verifies that the materialized view you are creating is eligible for fast refresh.

FORCE
Oracle Database performs a fast refresh if possible, otherwise a complete refresh

NA
Not Applicable

NEVER
User specified that the Oracle Database should not refresh this materialized view

Enum Constant Detail

NEVER

public static final MaterializedView.RefreshMethod NEVER

User specified that the Oracle Database should not refresh this materialized view

FAST

public static final MaterializedView.RefreshMethod FAST

Oracle Database performs an incremental refresh applying changes that correspond to changes in the masters since the last refresh When you specify FAST refresh at create time, Oracle Database verifies that the materialized view you are creating is eligible for fast refresh. When you change the refresh method to FAST in an ALTER MATERIALIZED VIEW statement, Oracle Database does not perform this verification. If the materialized view is not eligible for fast refresh, Oracle Database returns an error when you attempt to refresh this view.

COMPLETE

public static final MaterializedView.RefreshMethod COMPLETE

Materialized view is completely refreshed from the masters

FORCE

public static final MaterializedView.RefreshMethod FORCE

Oracle Database performs a fast refresh if possible, otherwise a complete refresh

NA

public static final MaterializedView.RefreshMethod NA

Not Applicable

Method Detail

values

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

Returns:

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

valueOf

public static MaterializedView.RefreshMethod 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 name

java.lang.NullPointerException - if the argument is null
