Class QualifiedNameValueConverter

java.lang.Object
  org.eclipse.xtext.conversion.impl.AbstractValueConverter<java.lang.String>
      org.eclipse.xtext.conversion.impl.QualifiedNameValueConverter

All Implemented Interfaces:

IValueConverter<java.lang.String>

Direct Known Subclasses:

StaticQualifierValueConverter

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.

getNamespaceDelimiter

@Deprecated
protected java.lang.String getNamespaceDelimiter()

Deprecated. use getStringNamespaceDelimiter() or getValueNamespaceDelimiter().

getStringNamespaceDelimiter

protected java.lang.String getStringNamespaceDelimiter()

Returns the used delimiter in the concrete syntax.

Returns:

the delimiter in the concrete syntax.

getValueNamespaceDelimiter

protected java.lang.String getValueNamespaceDelimiter()

Returns the used delimiter in the AST.

Returns:

the delimiter in the AST.

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.

Parameters:

value - the to-be-transformed value

Returns:

a string represenation for that value.

toValue

public java.lang.String toValue(java.lang.String string,
                                INode node)
                         throws ValueConverterException

Description copied from interface: IValueConverter

Creates a value from the given input. The input is conformant to a data type or terminal rule.

The given string or node may be null but not both of them.

Parameters:

string - the string that was inferred from the node. Usually the node's text but may be reduced to the parts of the node that are not hidden.

node - the parsed node including hidden parts.

Returns:

the new value or null.

Throws:

ValueConverterException - indicates that the string or node did not fulfil the expected format.
