Element Detail

name

public abstract String name

This represents the name of the XML attribute. Annotated fields or methods can optionally provide the name of the XML attribute they represent. If a name is not provided then the field or method name is used in its place. A name can be specified if the field or method name is not suitable for the XML attribute.

Returns:

the name of the XML attribute this represents

Default:

""

revision

public abstract double revision

This represents the revision of the class. A revision is used by the deserialization process to determine how to match the annotated fields and methods to the XML elements and attributes. If the version deserialized is different to the annotated revision then annotated fields and methods are not required and if there are excessive XML nodes they are ignored.

Returns:

this returns the version of the XML class schema

Default:

1.0

required

public abstract boolean required

Determines whether the version is required within an XML element. Any field marked as not required will not have its value set when the object is deserialized. This is written only if the version is not the same as the default version.

Returns:

true if the version is required, false otherwise

Default:

false
