All Implemented Interfaces:

Expression

public final class MaxFunction
extends AggregateFunction

One of the aggregate functions. The arguments must correspond to orderable state-field types (i.e., numeric types, string types, character types, or date types). The return type of this function is based on the state-field's type.

BNF: expression ::= MAX([DISTINCT] state_field_path_expression)
