Groups collection of objects by given object property using provided groupOrder

Parameters:

objects - - Collection of objects to group

groupBy - - Name of the property to group objects in the original collection

groupOrder - - Indicates how groups should be sorted. If groupOrder is null then group order is preserved the same as iteration order of the original collection. If groupOrder equals to "asc" or "desc" (case insensitive) groups will be sorted accordingly

select - - binary expression used to select which items go in the collection

configuration - - Configuration class for this transformation

Returns:

Collection of GroupData objects containing group data and collection of corresponding group items

Throws:

java.lang.NoSuchMethodException - - Thrown when there is an error accessing given bean property by reflection

java.lang.IllegalAccessException - - Thrown when there is an error accessing given bean property by reflection

java.lang.reflect.InvocationTargetException - - Thrown when there is an error accessing given bean property by reflection
