Detailed Description

Type used to represent generated extensions. The protocol compiler generates a static singleton instance of this class for each extension.

For example, imagine you have the

.proto 

file:

option java_class = "MyProto";

message Foo {
  extensions 1000 to max;
}

extend Foo {
  optional int32 bar;
}

Then,

MyProto.Foo.bar 

has type

GeneratedExtension<MyProto.Foo, Integer> 

.

In general, users should ignore the details of this type, and simply use these static singletons as parameters to the extension accessors defined in ExtendableMessage and ExtendableBuilder.

Member Function Documentation

fromReflectionType()

Object com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.fromReflectionType ( final Object  value )

inlineprotected

Convert from the type used by the reflection accessors to the type used by native accessors. E.g., for enums, the reflection accessors use EnumValueDescriptors but the native accessors use the generated enum type.

Definition at line 1852 of file GeneratedMessage.java.

getDefaultValue()

Type com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.getDefaultValue ( )

inline

Definition at line 1951 of file GeneratedMessage.java.

getDescriptor()

FieldDescriptor com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.getDescriptor ( )

inline

Definition at line 1822 of file GeneratedMessage.java.

getExtensionType()

ExtensionType com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.getExtensionType ( )

inlineprotected

Definition at line 1840 of file GeneratedMessage.java.

getLiteType()

WireFormat.FieldType com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.getLiteType ( )

inline

Definition at line 1940 of file GeneratedMessage.java.

getMessageDefaultInstance()

Message com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.getMessageDefaultInstance ( )

inline

If the extension is an embedded message or group, returns the default instance of the message.

Definition at line 1835 of file GeneratedMessage.java.

getNumber()

int com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.getNumber ( )

inline

Definition at line 1935 of file GeneratedMessage.java.

internalInit()

void com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.internalInit ( final FieldDescriptor  descriptor )

inline

For use by generated code only.

Definition at line 1801 of file GeneratedMessage.java.

isRepeated()

boolean com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.isRepeated ( )

inline

Definition at line 1945 of file GeneratedMessage.java.

singularFromReflectionType()

Object com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.singularFromReflectionType ( final Object  value )

inlineprotected

Like fromReflectionType(Object), but if the type is a repeated type, this converts a single element.

Definition at line 1876 of file GeneratedMessage.java.

singularToReflectionType()

Object com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.singularToReflectionType ( final Object  value )

inlineprotected

Like toReflectionType(Object), but if the type is a repeated type, this converts a single element.

Definition at line 1924 of file GeneratedMessage.java.

toReflectionType()

Object com.google.protobuf.GeneratedMessage.GeneratedExtension< ContainingType extends Message, Type >.toReflectionType ( final Object  value )

inlineprotected

Convert from the type used by the native accessors to the type used by reflection accessors. E.g., for enums, the reflection accessors use EnumValueDescriptors but the native accessors use the generated enum type.

Definition at line 1901 of file GeneratedMessage.java.
