Constructor Detail

FieldAccessorTable

public FieldAccessorTable(Descriptors.Descriptor descriptor,
                          java.lang.String[] camelCaseNames,
                          java.lang.Class<? extends GeneratedMessageV3> messageClass,
                          java.lang.Class<? extends GeneratedMessageV3.Builder<?>> builderClass)

Construct a FieldAccessorTable for a particular message class. Only one FieldAccessorTable should ever be constructed per class.

Parameters:

descriptor - The type's descriptor.

camelCaseNames - The camelcase names of all fields in the message. These are used to derive the accessor method names.

messageClass - The message type.

builderClass - The builder type.

FieldAccessorTable

public FieldAccessorTable(Descriptors.Descriptor descriptor,
                          java.lang.String[] camelCaseNames)

Construct a FieldAccessorTable for a particular message class without initializing FieldAccessors.

Method Detail

ensureFieldAccessorsInitialized

public GeneratedMessageV3.FieldAccessorTable ensureFieldAccessorsInitialized(java.lang.Class<? extends GeneratedMessageV3> messageClass,
                                                                             java.lang.Class<? extends GeneratedMessageV3.Builder<?>> builderClass)

Ensures the field accessors are initialized. This method is thread-safe.

Parameters:

messageClass - The message type.

builderClass - The builder type.

Returns:
