DataModelConverter (Wikidata Toolkit Data Model 0.3.0 API)

java.lang.Object
- org.wikidata.wdtk.datamodel.helpers.DataModelConverter

All Implemented Interfaces:

SnakVisitor<Snak>, ValueVisitor<Value>
```
public class DataModelConverter
extends Object
implements SnakVisitor<Snak>, ValueVisitor<Value>
```
Class to re-create data model objects using a specified factory. This is provided in place of having copy constructors in each and every implementation of the data model. Note that data model objects are usually immutable and do not need to be copied. The use of this class is to convert data objects to a specific implementation, as might be needed for some specialized purpose (e.g., for JSON export).

    Description copied from interface: SnakVisitor
    
    Visits a ValueSnak and returns a result.
    
    Specified by:
    
    visit in interface SnakVisitor<Snak>
    
    Parameters:
    snak - the snak to visit
    
    Returns:
    the result for this snak
  - visit
```
public Snak visit(SomeValueSnak snak)
```
    Description copied from interface: SnakVisitor
    
    Visits a SomeValueSnak and returns a result.
    
    Specified by:
    
    visit in interface SnakVisitor<Snak>
    
    Parameters:
    snak - the snak to visit
    
    Returns:
    the result for this snak
  - visit
```
public Snak visit(NoValueSnak snak)
```
    Description copied from interface: SnakVisitor
    
    Visits a NoValueSnak and returns a result.
    
    Specified by:
    
    visit in interface SnakVisitor<Snak>
    
    Parameters:
    snak - the snak to visit
    
    Returns:
    the result for this snak
  - convertValue
```
public Value convertValue(Value value)
```
  - visit
```
public Value visit(DatatypeIdValue value)
```
    Description copied from interface: ValueVisitor
    
    Visits a DatatypeIdValue and returns a result. This type of value does not occur in snaks, so some implementation will not need this method.
    
    Specified by:
    
    visit in interface ValueVisitor<Value>
    
    Parameters:
    value - the value to visit
    
    Returns:
    the result for this value
  - visit
```
public Value visit(EntityIdValue value)
```
    Description copied from interface: ValueVisitor
    
    Visits a EntityIdValue and returns a result. In practice, only specific subtypes of EntityIdValue are used, such as ItemIdValue and PropertyIdValue. Since the set of possible subtypes can be extended by extensions of Wikibase, the visitor only visits the general (abstract) supertype. Implementations will have to decide if the given specific type is supported and what to do with it.
    
    Specified by:
    
    visit in interface ValueVisitor<Value>
    
    Parameters:
    value - the value to visit
    
    Returns:
    the result for this value
  - visit
```
public Value visit(GlobeCoordinatesValue value)
```
    Description copied from interface: ValueVisitor
    
    Visits a GlobeCoordinatesValue and returns a result.
    
    Specified by:
    
    visit in interface ValueVisitor<Value>
    
    Parameters:
    value - the value to visit
    
    Returns:
    the result for this value
  - visit
```
public Value visit(MonolingualTextValue value)
```
    Description copied from interface: ValueVisitor
    
    Visits a MonolingualTextValue and returns a result.
    
    Specified by:
    
    visit in interface ValueVisitor<Value>
    
    Parameters:
    value - the value to visit
    
    Returns:
    the result for this value
  - visit
```
public Value visit(QuantityValue value)
```
    Description copied from interface: ValueVisitor
    
    Visits a QuantityValue and returns a result.
    
    Specified by:
    
    visit in interface ValueVisitor<Value>
    
    Parameters:
    value - the value to visit
    
    Returns:
    the result for this value
  - visit
```
public Value visit(StringValue value)
```
    Description copied from interface: ValueVisitor

    Specified by:
    
    visit in interface ValueVisitor<Value>
    
    Parameters:
    value - the value to visit
    
    Returns:
    the result for this value
  - visit
```
public Value visit(TimeValue value)
```
    Description copied from interface: ValueVisitor
    
    Visits a TimeValue and returns a result.
    
    Specified by:
    
    visit in interface ValueVisitor<Value>
