Enum Constant Detail

NAME

public static final Metadata._Fields NAME

Name of geo time serie (class name).

LABELS

public static final Metadata._Fields LABELS

Labels associated with the geo time serie

CLASS_ID

public static final Metadata._Fields CLASS_ID

classId associated with the geo time serie

LABELS_ID

public static final Metadata._Fields LABELS_ID

labelsId associated with the geo time serie

ATTRIBUTES

public static final Metadata._Fields ATTRIBUTES

Attributes associated with the geo time serie. Attributes are very similar to labels, except they are mutable, i.e. they don't contribute to the labelsId computation. They can be used to search GTS instances and store external data.

SOURCE

public static final Metadata._Fields SOURCE

Optional field indicating the source of the metadata. This is used mainly between components to decide whether or not to read/write metadata from/to persistent storage, i.e. to differentiate between updates and discovery of metadata.

LAST_ACTIVITY

public static final Metadata._Fields LAST_ACTIVITY

Timestamp (in ms since the Epoch) of the last observed activity on this Geo Time Series. Activity can be update, attribute changes or deletions depending on the configuration. This field is used to select GTS which have had (or not) activity after a given moment in time. The last activity timestamp is an estimate of the moment of the last activity, its resolution depends on the configuration of the activity window in Warp 10.

Method Detail

values

public static Metadata._Fields[] 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 (Metadata._Fields c : Metadata._Fields.values())
    System.out.println(c);

Returns:

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

valueOf

public static Metadata._Fields 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

findByThriftId

public static Metadata._Fields findByThriftId(int fieldId)

Find the _Fields constant that matches fieldId, or null if its not found.

findByThriftIdOrThrow

public static Metadata._Fields findByThriftIdOrThrow(int fieldId)

Find the _Fields constant that matches fieldId, throwing an exception if it is not found.

findByName

public static Metadata._Fields findByName(java.lang.String name)

Find the _Fields constant that matches name, or null if its not found.
