Method Detail

embedIvmlEditor

public static IEmbeddedEditor embedIvmlEditor(java.net.URI file,
                                              org.eclipse.swt.widgets.Composite parent)

Embeds an IVML editor for the given resource into the given parent.

Parameters:

file - the file representing the resource

parent - the parent UI component

Returns:

the embedded editor (or null if embedding failed)

getInjector

private static com.google.inject.Injector getInjector()

embedIvmlConstraintEditor

public static IEmbeddedEditor embedIvmlConstraintEditor(ModelInfo<Project> info,
                                                        org.eclipse.swt.widgets.Composite parent,
                                                        ConstraintSplitWriter.IConstraintFilter filter,
                                                        boolean trimParenthesis)

Embeds an IVML editor for the constraint indicated by filter in given resource into the given parent.

Parameters:

info - the model information of the containing project

parent - the parent UI component

filter - the constraint filter indicating then constraint to embed into the editor

trimParenthesis - shifts the outermost parenthesis pair to the model context

Returns:

the embedded editor (or null if embedding failed)

setConstraint

public static void setConstraint(IEmbeddedEditor editor,
                                 ModelInfo<Project> info,
                                 ConstraintSplitWriter.IConstraintFilter filter,
                                 boolean trimParenthesis)

Sets new content for the given editor.

Parameters:

editor - the editor to set the content on

info - the model information of the containing project

filter - the constraint filter indicating then constraint to embed into the editor

trimParenthesis - shifts the outermost parenthesis pair to the model context

obtainExpression

public static ConstraintSyntaxTree obtainExpression(IEmbeddedEditor editor,
                                                    ModelInfo<Project> info,
                                                    IModelElement context)
                                             throws CSTSemanticException,
                                                    ConstraintSyntaxException

Obtains the edited expression from an editor created by #embedIvmlConstraintEditor(ModelInfo, Composite, IConstraintFilter).

Parameters:

editor - the editor

info - the model information of the containing project

context - the context to resolve the expression within, see ModelUtility.createExpression(String, IModelElement), if null, the resolved project from info is taken

Returns:

the edited expression

Throws:

CSTSemanticException - in case of semantic problems in the constraint

ConstraintSyntaxException - in case of syntax problems in the constraint
