"merged" (mapping::merged)

This function creates a new instance by merging two mappings.

Synopsis

mapping mapping.merged(mapping other);


Parameter	Description
other	Mapping to be merged.

The function works similarly to "merge", but creates a new instance. In this case the used mapping will not be changed.

The resulting mapping is a new copy of the used mapping, merged with the "other" mapping given as a parameter.

Example

Merging mappings "map" and "other".

main()
{
mapping m1 = makeMapping("one", 1);
mapping m2 = m1.merged(makeMapping("two", 2));
}

As a result, the mapping "m2" will then contain both key/value pairs:

WCCOAui1:[mapping 2 items
WCCOAui1:   "two" : 2
WCCOAui1:   "one" : 1
WCCOAui1:]

While the mapping "m2" will still contain the "one" element:

WCCOAui1:[mapping 1 items
WCCOAui1:   "one" : 1
WCCOAui1:]
