Modern OrderedSet OrderedSetIterator

OrderedSetIterator

Holds a position in an OrderedSet, stepping in ascending order.

Syntax

OrderedSetIterator( of T )

Notes

• The iterator protocol -- IsValid, Value, MoveNext -- which is what for each is rewritten into. Ordinary code names the type only when the loop has to stop early, resume, or interleave with another.
• In ascending order, which is the difference from SetIterator.
• An in-order tree walk.

Examples

#import "std/containers"
using containers

dim s as OrderedSet( of integer )
s.Add( 30 ) : s.Add( 10 ) : s.Add( 20 )

dim it as OrderedSetIterator( of integer ) = s.GetIterator( )
while it.IsValid( )
    print it.Value( );       '' 10 20 30
    it.MoveNext( )
wend
print
