org.springframework.core.convert.support.FallbackObjectToStringConverter

All Implemented Interfaces:

ConditionalConverter, ConditionalGenericConverter, GenericConverter

final class FallbackObjectToStringConverter
extends java.lang.Object
implements ConditionalGenericConverter

Simply calls Object.toString() to convert any supported object to a String.

Supports CharSequence, StringWriter, and any class with a String constructor or one of the following static factory methods: valueOf(String), of(String), from(String).

Used by the DefaultConversionService as a fallback if there are no other explicit to-String converters registered.

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
