Method Detail

values

public static Meta.DatabaseProperty[] 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 (Meta.DatabaseProperty c : Meta.DatabaseProperty.values())
    System.out.println(c);

Returns:

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

valueOf

public static Meta.DatabaseProperty 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

NullPointerException - if the argument is null

getProp

public <T> T getProp(Meta meta,
            Meta.ConnectionHandle ch,
            Class<T> aClass)

Returns a value of this property, using the default value if the map does not contain an explicit value.

getProp

public <T> T getProp(Map<Meta.DatabaseProperty,Object> map,
            Class<T> aClass)

Returns a value of this property, using the default value if the map does not contain an explicit value.

fromProto

public static Meta.DatabaseProperty fromProto(Common.DatabaseProperty proto)

toProto

public Common.DatabaseProperty toProto()
