The constructor.

Method Detail

getSourceType

public final Class<Object> getSourceType()

This the type of the value accepted by this converter. Use Object if you want to accept any value. A very common source-type is String.

Specified by:

getSourceType in interface ValueConverter<Object,Object>

Returns:

the source-type.

getTargetType

public final Class<Object> getTargetType()

Is the guaranteed return-type of the conversion. This information is used externally to choose the most specific ValueConverter that is appropriate for the conversion.
E.g. a generic converter can have Object as target-type while a specific converter may have Collection as target-type. Now if an object (compliant with the source-type) needs to be converted to a Collection or List, the specific converter is used while for other objects the generic converter is chosen.
Please note that the target-type is often more general than the actual returned result. So a ValueConverter that converts a comma-separated String to an ArrayList will typically declare List as target-type.

Specified by:

getTargetType in interface ValueConverter<Object,Object>

Returns:

the target-type.
