Imports
java.util.Map, org.eclipse.persistence.expressions.Expression, .ExpressionOperator, .ListExpressionOperator, org.eclipse.persistence.internal.databaseaccess.DatabasePlatform
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.

public void setOperator(ExpressionOperator theOperator)

Overrides org.eclipse.persistence.internal.expressions.FunctionExpression.setOperator.

INTERNAL: Set the operator for this expression. The operator must be a ListExpressionOperator This method asserts that the passed argument is a ListExpressionOperator rather than throwing an exception since this method is entirely internal and the user should never get this behavior
