Detailed Description

The DomainMerger class merges domains, when possible

Constructor & Destructor Documentation

DomainMerger::DomainMerger

(

)

Constructor for an empty DomainMerger

DomainMerger::DomainMerger	(	const IDomain &	dom1,
		const IDomain &	dom2
	)

Creates a DomainMerger from 2 IDomain 's
Does not yet do the actual merging
the domains may not be null

Parameters

dom1	an IDomain you want merged
dom2	an IDomain you want merged

Member Function Documentation

virtual bool Ilwis::DomainMerger::merge ( )

pure virtual

merges the 2 domains, which have been specified in the constructor
requires the 2 domains to be compatible. the actual merging details are in the relevant subclasses

Returns

true when the merging was succesfull

IDomain DomainMerger::mergedDomain

(

)

const

Query for the merged domain in this DomainMerger
based on the 2 domains specified in the constructor
only works after the domains have been merged, if the domains have not yet been merged this will return null

Returns

the result of the merging

IDomain DomainMerger::mergeDomains	(	const IDomain &	dom1,
		const IDomain &	dom2
	)

Merges the domains and returns the result
for a merge to work the domains must be valid and must have the same valuetypes

the merged domain will be saved in this domainmerger
which means if you want to acces an already merged domain again you should use mergedDomain() instead of this

Parameters

dom1	first domain to be merged
dom2	second domain to be merged

Returns

the result of the merge, can be null if the domains are not compatible

std::map< quint32, quint32 > DomainMerger::renumberer

(

)

const

Query for the renumberer
the renumberer is the map that is used to renumber the elements in the 2 soon to be merged domains

Returns

the renumberer (a map<quint32,quint32>)
