Class TransformerDefinition

  • Direct Known Subclasses:
    CustomTransformerDefinition, DataFormatTransformerDefinition, EndpointTransformerDefinition
    @Metadata(label="transformation")
public abstract class TransformerDefinition
extends Object
    Represents a Transformer which declarative transforms message content according to the input type declared by InputTypeDefinition and/or output type declared by OutputTypeDefinition. If you specify from='java:com.example.ABC' and to='xml:XYZ', the transformer will be picked up when current message type is 'java:com.example.ABC' and expected message type is 'xml:XYZ'. If you specify from='java' to='xml', then it will be picked up for all of Java to xml transformation. Also it's possible to specify scheme='xml' so that the transformer will be picked up for all of Java to xml and xml to java transformation.

      • getScheme

        public String getScheme()

      • setScheme

        public void setScheme​(String scheme)
        Set a scheme name supported by the transformer. If you specify 'csv', the transformer will be picked up for all of 'csv' from/to Java transformation. Note that the scheme matching is performed only when no exactly matched transformer exists.
        Parameters:
        scheme - scheme name

      • getFromType

        public String getFromType()

      • setFromType

        public void setFromType​(String from)
        Set the 'from' data type name. If you specify 'xml:XYZ', the transformer will be picked up if source type is 'xml:XYZ'. If you specify just 'xml', the transformer matches with all of 'xml' source type like 'xml:ABC' or 'xml:DEF'.
        Parameters:
        from - 'from' data type name

      • setFromType

        public void setFromType​(Class<?> clazz)
        Set the 'from' data type using Java class.
        Parameters:
        clazz - 'from' Java class

      • getToType

        public String getToType()

      • setToType

        public void setToType​(String to)
        Set the 'to' data type name. If you specify 'json:XYZ', the transformer will be picked up if destination type is 'json:XYZ'. If you specify just 'json', the transformer matches with all of 'json' destination type like 'json:ABC' or 'json:DEF'.
        Parameters:
        to - 'to' data type name

      • setToType

        public void setToType​(Class<?> clazz)
        Set the 'to' data type using Java class.
        Parameters:
        clazz - 'to' Java class
