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

matchesFromByteBuffer

private boolean matchesFromByteBuffer(TypeDescriptor targetType)

matchesToByteBuffer

private boolean matchesToByteBuffer(TypeDescriptor sourceType)

convert

@Nullable
public Object convert(@Nullable
 Object source,
 TypeDescriptor sourceType,
 TypeDescriptor targetType)

从接口复制的说明: GenericConverter

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

返回:

the converted object

convertFromByteBuffer

@Nullable
private Object convertFromByteBuffer(ByteBuffer source,
 TypeDescriptor targetType)

convertToByteBuffer

private Object convertToByteBuffer(@Nullable
 Object source,
 TypeDescriptor sourceType)
