Lexer Tokens›

EOF

The end-of-file token, built into the ANTLR runtime. Used in the top-level library rule to assert that the entire input has been consumed. It is not a character sequence but a virtual marker emitted by the lexer when the input stream is exhausted.

Examples

library MyLibrary version '1.0.0'

using FHIR version '4.0.1'
