public AbstractTypeConverterRuleFixedSourceAnyDestination(@Nonnull

Method Detail

canConvert

public final boolean canConvert(@Nonnull
                 Class<?> aSrcClass,
                 @Nonnull
                 Class<?> aDstClass)

Description copied from interface: ITypeConverterRule

Check if this converter can handle the conversion from the passed source to the passed destination class. Note: as this method is called for every type conversion for which no exact converters are present, the implementation of this method should be as efficient as possible.

Parameters:

aSrcClass - Source class to convert from. Never null.

aDstClass - Destination class to convert to. Never null.

Returns:

true if conversion is possible, false otherwise.

getInBetweenValue

@Nonnull
protected abstract Object getInBetweenValue(@Nonnull
                               Object aSource)

convert

public final Object convert(@Nonnull
             Object aSource)

Description copied from interface: ITypeConverter

Convert the passed source object to the destination type.

Parameters:

aSource - The source object to be converted. Cannot be null because the type converter already filters null values!

Returns:

The converted value. May be null.

getSourceClass

@Nonnull
public final Class<?> getSourceClass()

toString

public String toString()

Overrides:
