# TibrvMsgField

Class

## Declaration

    class com.tibco.tibrv.TibrvMsgField
      extends java.lang.Object

## Purpose

Represent a message field.

## Remarks

This class has no `destroy()` method. Instead, the Java garbage collector reclaims storage automatically.

Field | Description
`name` | Field name, of type `java.lang.String`. Names must be strings; `null` is a special value that indicates no name. Field names use the character encoding appropriate to the ISO locale; see Strings and Character Encodings.
`id` | Field identifier, of type `int`. Identifiers must be in the range [0-65535]; zero is a special value that indicates no identifier.
`data` | Data content of the field, a `java.lang.Object`. When storing data in this field, Rendezvous software does not verify that the data and type of the field are consistent. Methods that add the field object into a message verify consistency (for example TibrvMsg.addField() and TibrvMsg.updateField()). It is illegal to add or update a field with `null` data.
`type` | Type designator for the data, a `short`. For a list of types, see Datatype Constants. To interpret a type designator as a string, see TibrvMsg.getTypeName(). When storing a type designator in this field, Rendezvous software does not verify that the data and type of the field are consistent. Methods that add the field object into a message verify consistency (for example TibrvMsg.addField() and TibrvMsg.updateField()). If absent, the default type is TibrvMsg.DEFAULT, which instructs TibrvMsg.addField() and TibrvMsg.updateField() to use the default type corresponding to the data value.

Method | Description
`TibrvMsgField()` | Create a message field object.
`TibrvMsgField.toString()` | Format a field as a string.

Inherited Methods
`java.lang.Object.equals` `java.lang.Object.getClass` `java.lang.Object.hashCode` `java.lang.Object.notify` `java.lang.Object.notifyAll` `java.lang.Object.wait`
