Jazradel	GetFilterUnit() refers to Matching Unit. Use it in a filter condition.

An example

JASS:

function MyFilter takes nothing returns boolean
    return GetWidgetLife( GetFilterUnit() ) < 50.0
endfunction

function test takes nothing returns nothing
 local group g=CreateGroup()
 local boolexpr B=Condition(function MyFilter)
     call GroupEnumUnitsInRange(g,0.0,0.0,100000.0, B)
     // the group g now contains units that have less than 50 hitpoints.
     call RemoveBoolExpr(B)
 set B=null
 set g=null
endfunction
