Package com.saperion.common.lang.conversion

Class ConcatenationConverter<SourceType,IntermediateType,TargetType>

java.lang.Object

com.saperion.common.lang.conversion.ConcatenationConverter<SourceType,IntermediateType,TargetType>

All Implemented Interfaces:

Converter<SourceType,TargetType>

public class ConcatenationConverter<SourceType,IntermediateType,TargetType>
extends java.lang.Object
implements Converter<SourceType,TargetType>

Concatenates two Converters to obtain another Converter. For a given Converter<T1, T2> A and a given Converter<T2, T3> A the ConcatenationConverter(A, B) will convert given instances of T1 to T3 by first converting to T2 with A and then to T3 with B.
