程序包 cn.taketoday.core.conversion.support

类 FallbackObjectToStringConverter

java.lang.Object

cn.taketoday.core.conversion.support.FallbackObjectToStringConverter

所有已实现的接口:

ConditionalConverter, ConditionalGenericConverter, GenericConverter

final class FallbackObjectToStringConverter
extends 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.

从以下版本开始:

3.0

方法详细资料

getConvertibleTypes

public Set<GenericConverter.ConvertiblePair> getConvertibleTypes()

从接口复制的说明: 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.

指定者:

getConvertibleTypes 在接口中 GenericConverter

matches

public boolean matches(TypeDescriptor sourceType,
 TypeDescriptor targetType)

从接口复制的说明: ConditionalConverter

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

指定者:

matches 在接口中 ConditionalConverter

参数:

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

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

返回:

true if conversion should be performed, false otherwise

convert

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

指定者:

convert 在接口中 GenericConverter

参数:

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
