What the function of TagGroupReleaseSeeds

Question

In the manual of DM script, it said the function of TagGroupReleaseSeeds is "Releases the seeds returned by 'TagGroupGetSeeds'." But I can't catch the meaning. Could anyone give me more explanation. Thanks.

It is unlikely that these commands are of much use to you.

Their purpose is to check the "dirty" state of a TagGroup (i.e. whether it changed since some other point in time.) Essentially, a TagGroup has an internal "counter" of changes which is increased whenever it is changed. You can use it like this:

ClearResults()
taggroup testTG = NewTagGroup()
Result("Seeds of Taggroup:\n")
Result( testTG.TagGroupGetSeeds() +"\n")
Result( testTG.TagGroupGetSeeds() +"\n")
testTG.TagGroupSetTagAsNumber("Dummy",-100)
Result( testTG.TagGroupGetSeeds() +"\n")
testTG.TagGroupSetTagAsNumber("Dummy",100)
Result( testTG.TagGroupGetSeeds() +"\n")
testTG.TagGroupSetTagAsNumber("Dummy2",-100)
Result( testTG.TagGroupGetSeeds() +"\n")
testTG.TagGroupMarkAsChanged()
Result( testTG.TagGroupGetSeeds() +"\n")

Result("\n Remember Tag state...") 
number seeds = testTG.TagGroupGetSeeds()
testTG.TagGroupSetTagAsString("str","dummy")

if ( testTG.TagGroupHasChangedSince(seeds) )
    Result("\n Tag was changed since remembered state...")
