    • getTransformationTemplate

      public String getTransformationTemplate()
       Optional. The CEL expression template to apply to transform messages.
 The following CEL extension functions are provided for
 use in this CEL expression:
 - merge:
 map1.merge(map2) -> map3
 - Merges the passed CEL map with the existing CEL map the
 function is applied to.
 - If the same key exists in both maps, if the key's value is type
 map both maps are merged else the value from the passed map is
 used.
 - denormalize:
 map.denormalize() -> map
 - Denormalizes a CEL map such that every value of type map or key
 in the map is expanded to return a single level map.
 - The resulting keys are "." separated indices of the map keys.
 - For example:
 {
 "a": 1,
 "b": {
 "c": 2,
 "d": 3
 }
 "e": [4, 5]
 }
 .denormalize()
 -> {
 "a": 1,
 "b.c": 2,
 "b.d": 3,
 "e.0": 4,
 "e.1": 5
 }
 - setField:
 map.setField(key, value) -> message
 - Sets the field of the message with the given key to the
 given value.
 - If the field is not present it will be added.
 - If the field is present it will be overwritten.
 - The key can be a dot separated path to set a field in a nested
 message.
 - Key must be of type string.
 - Value may be any valid type.
 - removeFields:
 map.removeFields([key1, key2, ...]) -> message
 - Removes the fields of the map with the given keys.
 - The keys can be a dot separated path to remove a field in a
 nested message.
 - If a key is not found it will be ignored.
 - Keys must be of type string.
 - toMap:
 [map1, map2, ...].toMap() -> map
 - Converts a CEL list of CEL maps to a single CEL map
 - toDestinationPayloadFormat():
 message.data.toDestinationPayloadFormat() -> string or bytes
 - Converts the message data to the destination payload format
 specified in Pipeline.Destination.output_payload_format
 - This function is meant to be applied to the message.data field.
 - If the destination payload format is not set, the function will
 return the message data unchanged.
 - toCloudEventJsonWithPayloadFormat:
 message.toCloudEventJsonWithPayloadFormat() -> map
 - Converts a message to the corresponding structure of JSON
 format for CloudEvents
 - This function applies toDestinationPayloadFormat() to the
 message data. It also sets the corresponding datacontenttype of
 the CloudEvent, as indicated by
 Pipeline.Destination.output_payload_format. If no
 output_payload_format is set it will use the existing
 datacontenttype on the CloudEvent if present, else leave
 datacontenttype absent.
 - This function expects that the content of the message will
 adhere to the standard CloudEvent format. If it doesn't then this
 function will fail.
 - The result is a CEL map that corresponds to the JSON
 representation of the CloudEvent. To convert that data to a JSON
 string it can be chained with the toJsonString function.
      string transformation_template = 1 [(.google.api.field_behavior) = OPTIONAL];
      Specified by:
      getTransformationTemplate in interface Pipeline.Mediation.TransformationOrBuilder
      Returns:
      The transformationTemplate.
