Method Detail

isInitialized

public boolean isInitialized()

Description copied from interface: MessageLite

Returns true if all required fields in the message and all embedded messages are set, false otherwise.

Specified by:

isInitialized in interface MessageLite

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(Message).

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.

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 is defined to be getDescriptor().hashCode() ^ map.hashCode(), where map is a map of field numbers to field values.

Specified by:

hashCode in interface Message

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code value for this message
