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.

getSourceClass

@Nonnull
public final Class<SRC> getSourceClass()

getDestinationClass

@Nonnull
public final Class<DST> getDestinationClass()

apply

@Nullable
public DST apply(@Nonnull
                 SRC 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.

toString

public String toString()

Overrides:

toString in class AbstractTypeConverterRule<SRC,DST>
