Method Detail

getEncodingType

public java.lang.String getEncodingType()

Description copied from interface: PayloadConverter

Each PayloadConverter has an Encoding Type that it handles.

Specified by:

getEncodingType in interface PayloadConverter

Returns:

encoding type that this converter handles.
