Class MicroEJMessageLite

java.lang.Object

com.google.protobuf.MicroEJMessageLite

public abstract class MicroEJMessageLite
extends Object

Base class for MicroEJ-generated protobuf messages.

Replaces GeneratedMessageLite for environments without java.lang.reflect. Generated message classes extend this and provide inline writeTo, mergeFrom, and getSerializedSize implementations — no schema engine or reflection needed.

Supports proto2 extensions via FieldSet and ExtensionRegistryLite.

Method Detail

addRepeatedExtension

public final <Type> void addRepeatedExtension(GeneratedMessageLite.GeneratedExtension<?,List<Type>> extension,
                                              Type value)

Add a repeated extension value. For use by generated Builder code.

clearExtension

public final void clearExtension(GeneratedMessageLite.GeneratedExtension<?,?> extension)

Clear an extension. For use by generated Builder code.

copyExtensionsFrom

public void copyExtensionsFrom(MicroEJMessageLite other)

Copy all extensions from another message. For use by generated Builder code.

ensureExtensionsAreMutable

protected com.google.protobuf.FieldSet<com.google.protobuf.GeneratedMessageLite.ExtensionDescriptor> ensureExtensionsAreMutable()

Ensure the extension FieldSet is mutable. For use by generated code.

extensionsAreEmpty

protected boolean extensionsAreEmpty()

Check if extensions are empty. For use by generated code.

extensionsAreEqual

protected boolean extensionsAreEqual(MicroEJMessageLite other)

Compare extensions with another message. For use by generated equals().

extensionsHashCode

protected int extensionsHashCode()

Hash code of extensions. For use by generated hashCode().

extensionsMakeImmutable

protected void extensionsMakeImmutable()

Make extensions immutable. For use by generated makeImmutable().

extensionsSerializedSize

protected int extensionsSerializedSize()

Returns the serialized size of all extension fields.

getDefaultInstanceForType

public abstract MicroEJMessageLite getDefaultInstanceForType()

Returns a new default (empty) instance of this message type.

getExtension

public final <Type> Type getExtension(GeneratedMessageLite.GeneratedExtension<?,List<Type>> extension,
                                      int index)

Get one element of a repeated extension.

getExtension

public final <Type> Type getExtension(GeneratedMessageLite.GeneratedExtension<?,Type> extension)

Get the value of an extension.

getExtensionCount

public final <Type> int getExtensionCount(GeneratedMessageLite.GeneratedExtension<?,List<Type>> extension)

Get the number of elements in a repeated extension.

getSerializedSize

public abstract int getSerializedSize()

Returns the number of bytes required to serialize this message.

getUnknownFields

public final UnknownFieldSetLite getUnknownFields()

hasExtension

public final <Type> boolean hasExtension(GeneratedMessageLite.GeneratedExtension<?,Type> extension)

Check if a singular extension is present.

isInitialized

public boolean isInitialized()

Returns true if all required fields are set (always true for proto3).

mergeExtensionFields

protected void mergeExtensionFields(MicroEJMessageLite other)

Merge extension fields from another message. Simple copy for singular fields, append for repeated fields. For use by generated builder code.

microejMerge

protected MicroEJMessageLite microejMerge(MicroEJMessageLite other)

Create a new message by merging this message with another of the same type. Generated code overrides this for message-type extension support.
