public final class Field
extends GeneratedMessage
implements FieldOrBuilder

 A single field of a message type.

 New usages of this message as an alternative to FieldDescriptorProto are
 strongly discouraged. This message does not reliability preserve all
 information necessary to model the schema and preserve semantics. Instead
 make use of FileDescriptorSet which preserves the necessary information.

Overrides:

getDescriptorForType in class GeneratedMessage

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

Specified by:

writeTo in interface MessageLite

Overrides:

writeTo in class GeneratedMessage

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 interface MessageLite

Overrides:

getSerializedSize in class GeneratedMessage

equals

public boolean equals(Object obj)

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.

Parameters:

obj - 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 AbstractMessage

Returns:

the hash code value for this message

Specified by:

getParserForType in interface MessageLite

Overrides:

getParserForType in class GeneratedMessage

getDefaultInstanceForType

public Field getDefaultInstanceForType()

Description copied from interface: MessageLiteOrBuilder

Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty.

They return the same thing.
