Properties
- ctype ↔ FieldOptions_CType
-
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!
getter/setter pair
- deprecated ↔ bool
-
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.
getter/setter pair
- hashCode → int
-
Calculates a hash code based on the contents of the protobuf.
no setterinherited
- info_ → BuilderInfo
-
no setteroverride
- isFrozen → bool
-
Returns
true
if this message is marked read-only. Otherwisefalse
.no setterinherited - jstype ↔ FieldOptions_JSType
-
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.
getter/setter pair
- lazy ↔ bool
-
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.
getter/setter pair
- packed ↔ bool
-
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.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
uninterpretedOption
→ PbList<
UninterpretedOption> -
The parser stores options it doesn't recognize here. See above.
no setter
- unknownFields → UnknownFieldSet
-
no setterinherited
- unverifiedLazy ↔ bool
-
unverified_lazy does no correctness checks on the byte stream. This should
only be used where lazy with verification is prohibitive for performance
reasons.
getter/setter pair
- weak ↔ bool
-
For Google-internal migration only. Do not use.
