package org.opendaylight.yangtools.yang.parser.rfc7950.ir

Intermediate representation of a YANG file. This is an Abstract Syntax Tree equivalent to ParseTree we get from ANTLR, except it is immutable and has a denser in-memory representation due to it not containing any metadata which is not required for the purposes of statement inference.

The main entry point into this package is IRStatement, which represents a single YANG statement. Every YANG file is required to contain exactly one top-level statement, module or submodule, hence an IRStatement also represents the significant contents of a YANG file. One way of creating an IRStatement is through AntlrSupport.createStatement(org.opendaylight.yangtools.yang.parser.antlr.YangStatementParser.FileContext).
