Class EclipseProjectPropertiesEncodingProvider

java.lang.Object

org.eclipse.xtext.parser.IEncodingProvider.Runtime

org.eclipse.xtext.parser.EclipseProjectPropertiesEncodingProvider

All Implemented Interfaces:

IEncodingProvider

public class EclipseProjectPropertiesEncodingProvider
extends IEncodingProvider.Runtime

Use this class to retrieve resource encodings from Eclipse project properties. The provider can be used without a running Eclipse context, but depends on resources being stored in Eclipse projects. Parts of the implementation are copied from org.eclipse.core.internal.preferences.EclipsePreferences.

Since:

2.8

Method Detail

getEncoding

public java.lang.String getEncoding(org.eclipse.emf.common.util.URI uri)

Description copied from interface: IEncodingProvider

Returns the encoding that should be used to read a resource from the given uri. If the uri is null, the default encoding for the language is returned. At runtime, the default encoding was either configured externally or it is obtained from the class Charset. In the UI environment, the encoding should usually be read from the workspace metadata.

Specified by:

getEncoding in interface IEncodingProvider

Overrides:

getEncoding in class IEncodingProvider.Runtime

Parameters:

uri - the uri of the specific resource or null to obtain the default encoding.
