Package cgif.parser Description

Classes to support the parsing of CGIF.

CGIF is generally supported as specified in Annex B of the Common Logic Standard, with the following constraints:

• Type identifiers and referent identifiers that contain only alphanumeric characters do not have to be delimited in any special way. For example, the identifier Harry may be rendered simply as Harry without delimiters. The set of alphanumeric characters is all the upper and lower case Roman letters, digits 0-9, and the underscore.
• All other type identifiers and referent identifiers must be delimited by double quotes; identical to the " symbol. A double quote itself may be included in the identifier as long as it is escaped as per Linux convention. For example, Edwin ("Buzz") Aldrin would be rendered in CGIF as "Edwin (\"Buzz\") Aldrin". The delimiting quotes are not part of the identifier as processed internally.
