Constructor Details

FieldAccessorTable

public FieldAccessorTable(Descriptors.Descriptor descriptor,
 String[] camelCaseNames,
 Class<? extends GeneratedMessage> messageClass,
 Class<? extends GeneratedMessage.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,
 String[] camelCaseNames)

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

Method Details

ensureFieldAccessorsInitialized

@CanIgnoreReturnValue
public GeneratedMessage.FieldAccessorTable ensureFieldAccessorsInitialized(Class<? extends GeneratedMessage> messageClass,
 Class<? extends GeneratedMessage.Builder<?>> builderClass)

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

Parameters:

messageClass - The message type.

builderClass - The builder type.

Returns:

this

getField

private GeneratedMessage.FieldAccessorTable.FieldAccessor getField(Descriptors.FieldDescriptor field)

Get the FieldAccessor for a particular field.

getOneof

private GeneratedMessage.FieldAccessorTable.OneofAccessor getOneof(Descriptors.OneofDescriptor oneof)

Get the OneofAccessor for a particular oneof.
