getnode directly from Java

Looking in programming guide.

merged[’d’] == 'def'

Is this intended behavior?

Each call to a non-existent key adds to the index with the value of the caller without the leaf set.

Kermit Kiser
Yes.

You are correct.

If you are asking why this happens, consider this statement:

merged["e","f"]="notdef"

Although merged["e"] has not been initialized, the node must exist in order to find merged["e","f"] since it is chained from the "e" node.

Ok. Thank you.

Does anybody have any sample code that uses it in that way?

Just trying to understand how or why the concept would solve some computing task or problem.

George Hovey-2
Jason,

merged = "?"
merged[1. 2]="defined"

I believe at one time even though merged[1] had not been defined, the setting of merged[1, 2] would succeed, without creating merged[1].  This led to an ugly situation:

1. 'Say  merged[1, 2]' produces "defined".
2. The same element is invisible to a 'Loop Over', because without merged[1] there is no clue that it exists.

If I remember correctly, the (silent) setting of merged[1} was added to avoid this ugly situation.  Personally, I thought it something the programmer probably didn't intend and really needed to know about; and deserved an Exception.

So the programmer needs to be aware that:

if merged["auto-incremented"] gets caught in a loop.

You will not know until memory is exhausted.
