Class TransformerKey

java.lang.Object
org.apache.camel.ValueHolder<String>
org.apache.camel.spi.TransformerKey
public final class TransformerKey extends ValueHolder<String>
Composite lookup key for the TransformerRegistry, encoding a from-DataType / to-DataType pair as a single string value for efficient map-based lookup.

The string form is "fromType/toType" when both ends are specified, or just "toType" when the from side is DataType.ANY (scheme-only transformer that applies to any input type). This normalization ensures that scheme-based transformers (e.g. all json:* conversions) can be resolved with a single registry lookup without iterating all registered transformers.
