Properties

The ctype option instructs the C++ code generator to use a different representation of the field than it normally would. See the specific options below. This option is not yet implemented in the open source release -- sorry, we'll try to include it in a future version!

Generated

from field: optional google.protobuf.FieldOptions.CType ctype = 1 [default = STRING];

debugRedact?: boolean

Indicate that the field value should not be printed out when using debug formats, e.g. when the field contains sensitive credentials.

Generated

from field: optional bool debug_redact = 16 [default = false];

deprecated?: boolean

Is this field deprecated? Depending on the target platform, this can emit Deprecated annotations for accessors, or it will be completely ignored; in the very least, this is a formalization for deprecating fields.

Generated

from field: optional bool deprecated = 3 [default = false];

The jstype option determines the JavaScript type used for values of the field. The option is permitted only for 64 bit integral and fixed types (int64, uint64, sint64, fixed64, sfixed64). A field with jstype JS_STRING is represented as JavaScript string, which avoids loss of precision that can happen when a large value is converted to a floating point JavaScript. Specifying JS_NUMBER for the jstype causes the generated JavaScript code to use the JavaScript "number" type. The behavior of the default option JS_NORMAL is implementation dependent.

This option is an enum to permit additional types to be added, e.g. goog.math.Integer.

Generated

from field: optional google.protobuf.FieldOptions.JSType jstype = 6 [default = JS_NORMAL];

lazy?: boolean

Should this field be parsed lazily? Lazy applies only to message-type fields. It means that when the outer message is initially parsed, the inner message's contents will not be parsed but instead stored in encoded form. The inner message will actually be parsed when it is first accessed.

This is only a hint. Implementations are free to choose whether to use eager or lazy parsing regardless of the value of this option. However, setting this option true suggests that the protocol author believes that using lazy parsing on this field is worth the additional bookkeeping overhead typically needed to implement it.

This option does not affect the public interface of any generated code; all method signatures remain the same. Furthermore, thread-safety of the interface is not affected by this option; const methods remain safe to call from multiple threads concurrently, while non-const methods continue to require exclusive access.

Note that implementations may choose not to check required fields within a lazy sub-message. That is, calling IsInitialized() on the outer message may return true even if the inner message has missing required fields. This is necessary because otherwise the inner message would have to be parsed in order to perform the check, defeating the purpose of lazy parsing. An implementation which chooses not to check required fields must be consistent about it. That is, for any particular sub-message, the implementation must either always check its required fields, or never check its required fields, regardless of whether or not the message has been parsed.

As of May 2022, lazy verifies the contents of the byte stream during parsing. An invalid byte stream will cause the overall parsing to fail.

Generated

from field: optional bool lazy = 5 [default = false];

packed?: boolean

The packed option can be enabled for repeated primitive fields to enable a more efficient representation on the wire. Rather than repeatedly writing the tag and type for each element, the entire array is encoded as a single length-delimited blob. In proto3, only explicit setting it to false will avoid using packed encoding.

Generated

from field: optional bool packed = 2;

Generated

from field: optional google.protobuf.FieldOptions.OptionRetention retention = 17;

Generated

from field: optional google.protobuf.FieldOptions.OptionTargetType target = 18;

uninterpretedOption: UninterpretedOption[]

The parser stores options it doesn't recognize here. See above.

Generated

from field: repeated google.protobuf.UninterpretedOption uninterpreted_option = 999;

unverifiedLazy?: boolean

unverified_lazy does no correctness checks on the byte stream. This should only be used where lazy with verification is prohibitive for performance reasons.

Generated

from field: optional bool unverified_lazy = 15 [default = false];

weak?: boolean

For Google-internal migration only. Do not use.

Generated

from field: optional bool weak = 10 [default = false];

Methods

  • Create a deep copy.

    Returns FieldOptions

  • Compare with a message of the same type.

    Parameters

    Returns boolean

  • Parse from binary data, merging fields.

    Repeated fields are appended. Map entries are added, overwriting existing keys.

    If a message field is already present, it will be merged with the new data.

    Parameters

    Returns FieldOptions

  • Parse a message from a JSON value.

    Parameters

    Returns FieldOptions

  • Parse a message from a JSON string.

    Parameters

    Returns FieldOptions

  • Retrieve the MessageType of this message - a singleton that represents the protobuf message declaration and provides metadata for reflection- based operations.

    Returns MessageType<FieldOptions>

  • Serialize the message to binary data.

    Parameters

    Returns Uint8Array

  • Override for serialization behavior. This will be invoked when calling JSON.stringify on this message (i.e. JSON.stringify(msg)).

    Note that this will not serialize google.protobuf.Any with a packed message because the protobuf JSON format specifies that it needs to be unpacked, and this is only possible with a type registry to look up the message type. As a result, attempting to serialize a message with this type will throw an Error.

    This method is protected because you should not need to invoke it directly -- instead use JSON.stringify or toJsonString for stringified JSON. Alternatively, if actual JSON is desired, you should use toJson.

    Returns JsonValue

  • Serialize the message to a JSON value, a JavaScript value that can be passed to JSON.stringify().

    Parameters

    Returns JsonValue

  • Serialize the message to a JSON string.

    Parameters

    Returns string

  • Parameters

    Returns FieldOptions

  • Parameters

    Returns FieldOptions

  • Parameters

    Returns FieldOptions
