public DefaultPropertyValueMapFactory()

Method Details

create

public Map<String,Object> create(Member member)

Creates a Map to be used for storing property string/value pairs for the specified Member.

This factory creates an Flat3Map if it appears that the provided member has less than 3 properties, and a HashMap if it appears that it has more than 3.

Guessing the number of properties can be tricky since some subclasses of Member

have additional properties that aren't explicitly declared. The most common offenders are the (@link mondrian.olap.Measure} implementations, which often have 4 or more undeclared properties, so if the member is a measure, the factory will create a HashMap.

Specified by:

create in interface RolapMemberBase.PropertyValueMapFactory

Parameters:

member - Member

Returns:

the Map instance to store property/value pairs
