Example 11 with Selection

use of org.eclipse.jdt.internal.corext.dom.Selection in project che by eclipse.

the class ExtractMethodAnalyzer method computeTypeVariables.

    // or are covered by the selection
    CompilationUnit compilationUnit = (CompilationUnit) fEnclosingBodyDeclaration.getRoot();

        ASTNode decl = compilationUnit.findDeclaringNode(bindings[i]);
        if (decl == null || (!selection.covers(decl) && decl.getParent() instanceof MethodDeclaration))
            result.add(bindings[i]);
    }
    // all all type variables which are needed since a local variable uses it
    for (int i = 0; i < fArguments.length; i++) {
        IVariableBinding arg = fArguments[i];
        ITypeBinding type = arg.getType();
