RE: when does JsonSlurper return LazyMap vs LazyValueMap ?
Thank you that helped a lot.
BTW the issue you posted https://issues.apache.org/jira/browse/GROOVY-7532 had
example code to walk the json map object and make hard references to objects (
LAX to Normal )
def slurpOpts = jsonSlurperLAX.parse(new File("test.conf"))
slurpOpts.each {k, v -> configOpts2.put(k, slurpOpts.get(k))}
I have a question about this simple example though. If the json is more
complex and has nested maps this solution would be incomplete correct?
I decided to use the following but I don’t know if it is overkill or even
valid. Any thoughts?
public Map<String, Object> deepCloneJsonMap(Object json){
Map<String, Object> result = new LinkedHashMap();
json.each {k, v ->
if( v instanceof Map )
result.put(k, deepCloneJsonMap(((Map<String,Object>)json).get(k)))
else
result.put(k, ((Map<String,Object>)json).get(k))
}
return result;
}
Thanks again.

I think the easiest way to do this if there are no nested objects is to create
a new Map from the LazyValueMap. If there are no nested objects then the
following would work.
def newMap = new LinkedHashMap(lazyValueMap)
newMap.mediaHash = mediaHash
If there are nested objects then it takes more work as you'd have to
recurse/iterate over each nested LazyValueMap and convert it as well. There's
an issue [1] requesting the ability to convert to a regular map.

In my environment I am seeing that JsonSlurper returns LazyMap in my test code
using the groovyConsole but it returns a LazyValueMap in my compiled java code.
I am trying to add a node to the json object and it works great in the
groovyConsole but fails in java.
This code works in the groovyConsole...
def slurper = new JsonSlurper()
def json = slurper.parseText( jsonTxt )
json.put("mediaHash", mediaHash)
// -- or --
json."mediaHash" = mediaHash
In the groovyConsole slurper.parseText() returns a LazyMap
But in Java it returns a LazyValueMap and I get the exception ... die("Not that
kind of map");
What is the correct way to add a node and why do I get different results?
Thanks

Re: when does JsonSlurper return LazyMap vs LazyValueMap ?
A simple question here. The jsonSlurper creates a ConfigObject but i cannot
find a way to add an entry to the ConfigObject with the ultimate intention of
writing the whole shebang back to the json text file whence it came. Any ideas
pls. .?

I think the easiest way to do this if there are no nested objects is to
create a new Map from the LazyValueMap. If there are no nested objects
then the following would work.
def newMap = new LinkedHashMap(lazyValueMap)
newMap.mediaHash = mediaHash
If there are nested objects then it takes more work as you'd have to
recurse/iterate over each nested LazyValueMap and convert it as well.
