Java Code Examples for org.eclipse.xtext.RuleCall

/**
 * Returns the source text assigned to the given feature of the given object. Does not work for multi-valued features. Optionally also converts the source
 * text using the corresponding value converter. Conversion is only performed for keywords, rule call or cross reference grammar rules.
 * <p>
 * This method does not perform a check to make sure the feature matches the given object.
 *
 * @param object
 *          the semantic object
 * @param feature
 *          the feature to be considered when parsing the parse tree model
 * @param convert
 *          {@code true} if the parsed string needs conversion using its value converter
 * @return the parsed string from the node model
