Java Code Examples for org.cqframework.cql.cql2elm.CqlTranslator#toXml()

/**
 * Evaluate the given expression, within the context of the given Person and timestamp.
 * The given expression will be wrapped in CQL and evaluated to produce, ideally, a Number.
 * Examples:
 *  - In: "10 + 3", Out: (Integer)13
 *  - In: "25 / 2", Out: (Double)12.5
 *  - In: "#{age} / 3", Person{age = 27}, Out: (Integer) 9
 * 
 * @param expression "CQL-lite" expression, with attribute references wrapped in "#{ attr }"
 * @param person Person to evaluate expression against.
 * @param time Timestamp
 * @return result of the expression
