Method Detail

getConvertibleTypes

public java.util.Set<GenericConverter.ConvertiblePair> getConvertibleTypes()

Description copied from interface: GenericConverter

Return the source and target types that this converter can convert between.

Each entry is a convertible source-to-target type pair.

For conditional converters this method may return null to indicate all source-to-target pairs should be considered.

Specified by:

getConvertibleTypes in interface GenericConverter

matches

public boolean matches(TypeDescriptor sourceType,
                       TypeDescriptor targetType)

Description copied from interface: ConditionalConverter

Should the conversion from sourceType to targetType currently under consideration be selected?

Specified by:

matches in interface ConditionalConverter

Parameters:

sourceType - the type descriptor of the field we are converting from

targetType - the type descriptor of the field we are converting to

Returns:

true if conversion should be performed, false otherwise

matchesFromByteBuffer

private boolean matchesFromByteBuffer(TypeDescriptor targetType)

matchesToByteBuffer

private boolean matchesToByteBuffer(TypeDescriptor sourceType)

convert

public java.lang.Object convert(java.lang.Object source,
                                TypeDescriptor sourceType,
                                TypeDescriptor targetType)

Description copied from interface: GenericConverter

Convert the source object to the targetType described by the TypeDescriptor.

Specified by:

convert in interface GenericConverter

Parameters:

source - the source object to convert (may be null)

sourceType - the type descriptor of the field we are converting from

targetType - the type descriptor of the field we are converting to

Returns:

the converted object

convertFromByteBuffer

private java.lang.Object convertFromByteBuffer(java.nio.ByteBuffer source,
                                               TypeDescriptor targetType)

convertToByteBuffer

private java.lang.Object convertToByteBuffer(java.lang.Object source,
                                             TypeDescriptor sourceType)
