Enum STCS.Frame

All Implemented Interfaces:
Serializable, Comparable<STCS.Frame>, java.lang.constant.Constable
Enclosing class:
STCS

public static enum STCS.Frame extends Enum<STCS.Frame>

List of all possible frames in an STC expression.

When no value is specified, the default one is UNKNOWNFRAME. The default value is also accessible through the attribute DEFAULT and it is possible to test whether a frame is the default with the function isDefault().

Note: The possible values listed in this enumeration are limited to the subset of STC-S described by the section "6 Use of STC-S in TAP (informative)" of the TAP Recommendation 1.0 (27th March 2010).
