Class GeneratedMessage.GeneratedExtension<ContainingType extends Message,Type>

java.lang.Object

org.apache.flink.statefun.sdk.shaded.com.google.protobuf.ExtensionLite<ContainingType,Type>

org.apache.flink.statefun.sdk.shaded.com.google.protobuf.Extension<ContainingType,Type>

org.apache.flink.statefun.sdk.shaded.com.google.protobuf.GeneratedMessage.GeneratedExtension<ContainingType,Type>

Enclosing class:

GeneratedMessage

@Generated(value="proto")
public static class GeneratedMessage.GeneratedExtension<ContainingType extends Message,Type>
extends Extension<ContainingType,Type>

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 GeneratedMessage.ExtendableMessage and GeneratedMessage.ExtendableBuilder.

Method Summary

Modifier and Type	Method and Description
protected java.lang.Object	fromReflectionType(java.lang.Object value) Convert from the type used by the reflection accessors to the type used by native accessors.
Type	getDefaultValue() Returns the default value of the extension field.
Descriptors.FieldDescriptor	getDescriptor() Returns the descriptor of the extension.
protected Extension.ExtensionType	getExtensionType()
WireFormat.FieldType	getLiteType() Returns the type of the field.
Message	getMessageDefaultInstance() If the extension is an embedded message or group, returns the default instance of the message.
int	getNumber() Returns the field number of the extension.
void	internalInit(Descriptors.FieldDescriptor descriptor) For use by generated code only.
boolean	isRepeated() Returns whether it is a repeated field.
protected java.lang.Object	singularFromReflectionType(java.lang.Object value) Like fromReflectionType(Object), but if the type is a repeated type, this converts a single element.
protected java.lang.Object	singularToReflectionType(java.lang.Object value) Like toReflectionType(Object), but if the type is a repeated type, this converts a single element.
protected java.lang.Object	toReflectionType(java.lang.Object value) Convert from the type used by the native accessors to the type used by reflection accessors.

Method Detail

internalInit

public void internalInit(Descriptors.FieldDescriptor descriptor)

For use by generated code only.

getDescriptor

public Descriptors.FieldDescriptor getDescriptor()

Description copied from class: Extension

Returns the descriptor of the extension.

Specified by:

getDescriptor in class Extension<ContainingType extends Message,Type>

getMessageDefaultInstance

public Message getMessageDefaultInstance()

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

Specified by:

getMessageDefaultInstance in class ExtensionLite<ContainingType extends Message,Type>

getExtensionType

protected Extension.ExtensionType getExtensionType()

Specified by:

getExtensionType in class Extension<ContainingType extends Message,Type>

fromReflectionType

protected java.lang.Object fromReflectionType(java.lang.Object value)

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.

Specified by:

fromReflectionType in class Extension<ContainingType extends Message,Type>

singularFromReflectionType

protected java.lang.Object singularFromReflectionType(java.lang.Object value)

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

Specified by:

singularFromReflectionType in class Extension<ContainingType extends Message,Type>

toReflectionType

protected java.lang.Object toReflectionType(java.lang.Object value)

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.

Specified by:

toReflectionType in class Extension<ContainingType extends Message,Type>

singularToReflectionType

protected java.lang.Object singularToReflectionType(java.lang.Object value)

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

Specified by:

singularToReflectionType in class Extension<ContainingType extends Message,Type>

getNumber

public int getNumber()

Description copied from class: ExtensionLite

Returns the field number of the extension.

Specified by:

getNumber in class ExtensionLite<ContainingType extends Message,Type>

getLiteType

public WireFormat.FieldType getLiteType()

Description copied from class: ExtensionLite

Returns the type of the field.

Specified by:

getLiteType in class ExtensionLite<ContainingType extends Message,Type>

isRepeated

public boolean isRepeated()

Description copied from class: ExtensionLite

Returns whether it is a repeated field.

Specified by:

isRepeated in class ExtensionLite<ContainingType extends Message,Type>

getDefaultValue

public Type getDefaultValue()

Description copied from class: ExtensionLite

Returns the default value of the extension field.

Specified by:

getDefaultValue in class ExtensionLite<ContainingType extends Message,Type>
