Constructor Detail

DozerConverter

public DozerConverter(Class<A> prototypeA,
                      Class<B> prototypeB)

Defines two types, which will take part transformation. As Dozer supports bi-directional mapping it is not known which of the classes is source and which is destination. It will be decided in runtime.

Parameters:

prototypeA - type one

prototypeB - type two

Method Detail

convert

public Object convert(Object existingDestinationFieldValue,
                      Object sourceFieldValue,
                      Class<?> destinationClass,
                      Class<?> sourceClass)

Specified by:

convert in interface CustomConverter

convertTo

public abstract B convertTo(A source,
                            B destination)

Converts the source field to the destination field and return the resulting destination value.

Parameters:

source - the value of the source field

destination - the current value of the destination field (or null)

Returns:

the resulting value for the destination field

convertTo

public B convertTo(A source)

Converts the source field to the destination field and return the resulting destination value.

Parameters:

source - the value of the source field

Returns:

the resulting value for the destination field

convertFrom

public abstract A convertFrom(B source,
                              A destination)

Converts the source field to the destination field and return the resulting destination value

Parameters:

source - the value of the source field

destination - the current value of the destination field (or null)

Returns:

the resulting value for the destination field

convertFrom

public A convertFrom(B source)

Converts the source field to the destination field and return the resulting destination value

Parameters:

source - the value of the source field

Returns:

the resulting value for the destination field

setParameter

public void setParameter(String parameter)

Sets the configured parameter value for this converter instance. Should be called by Dozer internally before actual mapping.

Specified by:

setParameter in interface ConfigurableCustomConverter

Parameters:

parameter - configured parameter value

getParameter

public String getParameter()

Retrieves the static parameter configured for this particular converter instance. It is not advisable to call this method from converter constructor as the parameter is not yet there.

Returns:

parameter value

Throws:

IllegalStateException - if parameter has not been set yet.
