    • getField

      String getField()
       A request field to extract the header key-value pair from.
       
      string field = 1;
      Returns:
      The field.
    • getFieldBytes

      com.google.protobuf.ByteString getFieldBytes()
       A request field to extract the header key-value pair from.
       
      string field = 1;
      Returns:
      The bytes for field.
    • getPathTemplate

      String getPathTemplate()
       A pattern matching the key-value field. Optional.
       If not specified, the whole field specified in the `field` field will be
       taken as value, and its name used as key. If specified, it MUST contain
       exactly one named segment (along with any number of unnamed segments) The
       pattern will be matched over the field specified in the `field` field, then
       if the match is successful:
       - the name of the single named segment will be used as a header name,
       - the match value of the segment will be used as a header value;
       if the match is NOT successful, nothing will be sent.
       Example:
                     -- This is a field in the request message
                    |   that the header value will be extracted from.
                    |
                    |                     -- This is the key name in the
                    |                    |   routing header.
                    V                    |
           field: "table_name"           v
           path_template: "projects/*/{table_location=instances/*}/tables/*"
                                                      ^            ^
                                                      |            |
             In the {} brackets is the pattern that --             |
             specifies what to extract from the                    |
             field as a value to be sent.                          |
                                                                   |
            The string in the field must match the whole pattern --
            before brackets, inside brackets, after brackets.
       When looking at this specific example, we can see that:
       - A key-value pair with the key `table_location`
         and the value matching `instances/*` should be added
         to the x-goog-request-params routing header.
       - The value is extracted from the request message's `table_name` field
         if it matches the full pattern specified:
         `projects/*/instances/*/tables/*`.
       **NB:** If the `path_template` field is not provided, the key name is
       equal to the field name, and the whole field should be sent as a value.
       This makes the pattern for the field and the value functionally equivalent
       to `**`, and the configuration
           {
             field: "table_name"
           }
       is a functionally equivalent shorthand to:
           {
             field: "table_name"
             path_template: "{table_name=**}"
           }
       See Example 1 for more details.
       
      string path_template = 2;
      Returns:
      The pathTemplate.

      com.google.protobuf.ByteString getPathTemplateBytes()
       A pattern matching the key-value field. Optional.

                                                      |            |

                                                                   |
