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];

Returns
Type Description
String

The transformationTemplate.

getTransformationTemplateBytes()

public ByteString getTransformationTemplateBytes()

Optional. The CEL expression template to apply to transform messages. The following CEL extension functions are provided for use in this CEL expression:

  • 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.
