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.

See also: MessageOrBuilder.getInitializationErrorString()

Specified by:

isInitialized in interface MessageLiteOrBuilder

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 call MessageLiteOrBuilder.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 interface MessageOrBuilder

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 call MessageLiteOrBuilder.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 interface MessageOrBuilder

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 around TextFormat.printToString(MessageOrBuilder).

Specified by:

toString in interface Message

Overrides:

toString in class java.lang.Object

writeTo

public void writeTo(CodedOutputStream output)
             throws java.io.IOException

Description copied from interface: MessageLite

Serializes the message and writes it to output. This does not flush or close the stream.

Specified by:

writeTo in interface MessageLite

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.

Specified by:

getSerializedSize in interface MessageLite

equals

public boolean equals(java.lang.Object other)

Description copied from interface: Message

Compares the specified object with this message for equality. Returns true if the given object is a message of the same type (as defined by getDescriptorForType()) and has identical values for all of its fields. Subclasses must implement this; inheriting Object.equals() is incorrect.

Specified by:

equals in interface Message

Overrides:

equals in class java.lang.Object

Parameters:

other - object to be compared for equality with this message

Returns:

true if the specified object is equal to this message

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; inheriting Object.hashCode() is incorrect.

Specified by:

hashCode in interface Message

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code value for this message

See Also:

Map.hashCode()

hashFields

protected 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

protected static int hashLong(long n)

Helper method for implementing Message.hashCode().

See Also:

Boolean.hashCode()

hashBoolean

protected static int hashBoolean(boolean b)

Helper method for implementing Message.hashCode().

See Also:

Boolean.hashCode()

hashEnum

protected static int hashEnum(Internal.EnumLite e)

Helper method for implementing Message.hashCode().

This is needed because Enum.hashCode() is final, but we need to use the field number as the hash code to ensure compatibility between statically and dynamically generated enum objects.

hashEnumList

protected static int hashEnumList(java.util.List<? extends Internal.EnumLite> list)

Helper method for implementing Message.hashCode().
