Method Detail

values

public static final SqlIntervalQualifier.TimeUnit[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(SqlIntervalQualifier.TimeUnit c : SqlIntervalQualifier.TimeUnit.values())
        System.out.println(c);

Returns:

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

valueOf

public static SqlIntervalQualifier.TimeUnit 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

getValue

public static SqlIntervalQualifier.TimeUnit getValue(int ordinal)

Returns the TimeUnit associated with an ordinal. The value returned is null if the ordinal is not a member of the TimeUnit enumeration.
