Class BinaryFormatImpl

java.lang.Object
io.opencensus.trace.propagation.BinaryFormat

final class BinaryFormatImpl extends BinaryFormat
Implementation of the BinaryFormat.

BinaryFormat format:

  • Binary value: <version_id><version_format>
  • version_id: 1-byte representing the version id.
  • For version_id = 0:
    • version_format: <field><field>
    • field_format: <field_id><field_format>
    • Fields:
      • TraceId: (field_id = 0, len = 16, default = "0000000000000000") - 16-byte array representing the trace_id.
      • SpanId: (field_id = 1, len = 8, default = "00000000") - 8-byte array representing the span_id.
      • TraceOptions: (field_id = 2, len = 1, default = "0") - 1-byte array representing the trace_options.
    • Fields MUST be encoded using the field id order (smaller to higher).
    • Valid value example:
      • {0, 0, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 1, 97, 98, 99, 100, 101, 102, 103, 104, 2, 1}
      • version_id = 0;
      • trace_id = {64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79}
      • span_id = {97, 98, 99, 100, 101, 102, 103, 104};
      • trace_options = {1};
