Method Details

getSubType

@Nonnull
ITypeConverterRule.ESubType getSubType()

Returns:

The sub type of the converter rule. May not be null.

canConvert

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

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.
