This module defines type checking utilities in the forms of dictionaries:
|
|
VALUE_CHECKERS: A dictionary of field types and a value validation object.
|
TYPE_TO_BYTE_SIZE_FN: A dictionary with field types and a size computing
|
function.
|
TYPE_TO_SERIALIZE_METHOD: A dictionary with field types and serialization
|
function.
|
FIELD_TYPE_TO_WIRE_TYPE: A dictionary with field typed and their
|
corresponding wire types.
|
TYPE_TO_DESERIALIZE_METHOD: A dictionary with field types and deserialization
|
function.

|
Args:
|
field: FieldDescriptor object for this field.
|
|
Returns:
|
An instance of TypeChecker which can be used to verify the types
|
of values assigned to a field of the specified type.
