Method Detail
-
isInitialized
public boolean isInitialized()
Description copied from interface:MessageLiteOrBuilder
Returns true if all required fields in the message and all embedded messages are set, false otherwise.- Specified by:
isInitialized
in interfaceMessageLiteOrBuilder
-
newBuilderForType
protected Message.Builder newBuilderForType(AbstractMessage.BuilderParent parent)
Create a nested builder.
-
findInitializationErrors
public java.util.List<java.lang.String> findInitializationErrors()
Description copied from interface:MessageOrBuilder
Returns a list of field paths (e.g. "foo.bar.baz") of required fields which are not set in this message. You should callMessageLiteOrBuilder.isInitialized()
first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.- Specified by:
findInitializationErrors
in interfaceMessageOrBuilder
-
getInitializationErrorString
public java.lang.String getInitializationErrorString()
Description copied from interface:MessageOrBuilder
Returns a comma-delimited list of required fields which are not set in this message object. You should callMessageLiteOrBuilder.isInitialized()
first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.- Specified by:
getInitializationErrorString
in interfaceMessageOrBuilder
-
hasOneof
public boolean hasOneof(Descriptors.OneofDescriptor oneof)
Description copied from interface:MessageOrBuilder
Returns true if the given oneof is set.- Specified by:
hasOneof
in interfaceMessageOrBuilder
-
getOneofFieldDescriptor
public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)
Description copied from interface:MessageOrBuilder
Obtains the FieldDescriptor if the given oneof is set. Returns null if no field is set.- Specified by:
getOneofFieldDescriptor
in interfaceMessageOrBuilder
-
toString
public final java.lang.String toString()
Description copied from interface:Message
Converts the message to a string in protocol buffer text format. This is just a trivial wrapper aroundTextFormat.Printer.printToString(MessageOrBuilder)
.
-
writeTo
public void writeTo(CodedOutputStream output) throws java.io.IOException
Description copied from interface:MessageLite
Serializes the message and writes it tooutput
. This does not flush or close the stream.- Specified by:
writeTo
in interfaceMessageLite
- Throws:
java.io.IOException
-
getSerializedSize
public int getSerializedSize()
Description copied from interface:MessageLite
Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that. If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will be smaller than the actual number of bytes required and might be negative.- Specified by:
getSerializedSize
in interfaceMessageLite
-
equals
public boolean equals(java.lang.Object other)
Description copied from interface:Message
Compares the specified object with this message for equality. Returnstrue
if the given object is a message of the same type (as defined bygetDescriptorForType()
) and has identical values for all of its fields. Subclasses must implement this; inheritingObject.equals()
is incorrect.
-
hashCode
public int hashCode()
Description copied from interface:Message
Returns the hash code value for this message. The hash code of a message should mix the message's type (object identity of the descriptor) with its contents (known and unknown field values). Subclasses must implement this; inheritingObject.hashCode()
is incorrect.
-
hashFields
protected static int hashFields(int hash, java.util.Map<Descriptors.FieldDescriptor,java.lang.Object> map)
Get a hash code for given fields and values, using the given seed.
-
hashLong
@Deprecated protected static int hashLong(long n)
Deprecated.from v3.0.0-beta-3+, for compatibility with v2.5.0 and v2.6.1 generated code.
-
hashBoolean
@Deprecated protected static int hashBoolean(boolean b)
Deprecated.from v3.0.0-beta-3+, for compatibility with v2.5.0 and v2.6.1 generated code.
-
hashEnum
@Deprecated protected static int hashEnum(Internal.EnumLite e)
Deprecated.from v3.0.0-beta-3+, for compatibility with v2.5.0 and v2.6.1 generated code.
-
hashEnumList
@Deprecated protected static int hashEnumList(java.util.List<? extends Internal.EnumLite> list)
Deprecated.from v3.0.0-beta-3+, for compatibility with v2.5.0 and v2.6.1 generated code.
