Examples with DefaultLinkingService org.eclipse.xtext.linking.impl.DefaultLinkingService used on opensource projects

Example 1 with DefaultLinkingService

use of org.eclipse.xtext.linking.impl.DefaultLinkingService in project xtext-core by eclipse.

the class PartialLinkingTest method replaceLinker.

protected void replaceLinker(XtextResource resource) {
    Linker linker = new Linker();
    DefaultLinkingService linkingService = new DefaultLinkingService();
    getInjector().injectMembers(linkingService);
    linkingService.setScopeProvider(this);
    linker.setLinkingService(linkingService);
    linker.setDiagnosticMessageProvider(new LinkingDiagnosticMessageProvider());
    linker.setLinkingHelper(getInjector().getInstance(LinkingHelper.class));
    resource.setLinker(linker);
}

Example 2 with DefaultLinkingService

use of org.eclipse.xtext.linking.impl.DefaultLinkingService in project dsl-devkit by dsldevkit.

the class ParseTreeUtil method getParsedStringUnchecked.

/**
 * Returns the source text assigned to the given feature of the given object. Does not work for multi-valued features. Optionally also converts the source
 * text using the corresponding value converter. Conversion is only performed for keywords, rule call or cross reference grammar rules.
 * <p>
 * This method does not perform a check to make sure the feature matches the given object.
 *
 * @param object
 *          the semantic object
 * @param feature
 *          the feature to be considered when parsing the parse tree model
 * @param convert
 *          {@code true} if the parsed string needs conversion using its value converter
 * @return the parsed string from the node model
