IfNotNull

case class IfNotNull(exprs: Map[String, Expression], thenClause: Seq[Expression], elseClause: Option[Seq[Expression]], pos: Option[String] = scala.None) extends Expression with Product with Serializable

Abstract syntax tree for an ifnotnull block.

exprs

variables to check for null

thenClause

expressions to evaluate if all variables are not null

elseClause

expressions to evaluate if present and any variable is null

pos

source file location from the locator mark

    Walk over tree applying a Task while checking for semantic errors.

    This is how Java is generated from an abstract syntax tree: the Task in that case is JVMCompiler.

    symbolTable

    used to look up symbols, cells, and pools

    functionTable

    used to look up functions

    engineOptions

    implementation options

    version

    version of the PFA language in which to interpret this PFA

    returns

    (information about this abstract syntax tree node after type-checking, result of the generic task)
