org.eclipse.persistence.internal.expressions.ArgumentListFunctionExpression
INTERNAL: This an extended FunctionExpression that allows the argument list to grow after it is created. New expressions may be added to the list and the printing of the database string is handled automatically This expression's addChild() method is used to construct the list. Note: This expression is designed to handle addition of children up until the first normalization (execution) of a query involving this expression. After normalization, the behavior is undefined. @see ListExpressionOperator @see Expression.coalesce() @see Expression.caseStatement() @author tware
