Direct Known Subclasses:

QualifiedNameInStaticImportValueConverter

public class QualifiedNameValueConverter
extends AbstractValueConverter<java.lang.String>

A value converter for qualified names consisting of segments or wildcard literals separated by namespace delimiters. Delegates to another value converter for the segments, thus enabling individual quoting of segments.

toString

public java.lang.String toString(java.lang.String value)

Description copied from interface: IValueConverter

Transforms the given value to a string that is conformant to the expected terminal or data type rule.
