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

Implements org.springframework.core.convert.converter.GenericConverter.convert.

Doc from org.springframework.core.convert.converter.GenericConverter.convert.

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

Parameters

public Set<GenericConverter.ConvertiblePair> getConvertibleTypes()

Implements org.springframework.core.convert.converter.GenericConverter.getConvertibleTypes.

Doc from org.springframework.core.convert.converter.GenericConverter.getConvertibleTypes.

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.

Parameters
sourceType:TypeDescriptor

the type descriptor of the field we are converting from

targetType:TypeDescriptor

the type descriptor of the field we are converting to

Returns:boolean

true if conversion should be performed, false otherwise
