All Implemented Interfaces:

org.eclipse.emf.common.notify.Adapter, org.eclipse.emf.common.notify.Adapter.Internal, org.eclipse.emf.common.util.ResourceLocator, org.eclipse.emf.edit.command.CreateChildCommand.Helper, org.eclipse.emf.edit.provider.IChangeNotifier, org.eclipse.emf.edit.provider.IDisposable

Direct Known Subclasses:

public class XSDItemProviderAdapter
extends org.eclipse.emf.edit.provider.ItemProviderAdapter
implements org.eclipse.emf.edit.command.CreateChildCommand.Helper

This is the base for all adapters. It takes handles the getParent() implementation that is need for XSDParticleItemProvider and XSDAttributeUseItemProvider to skip up to a particle or attribute use. It also supports CreateChildCommand by supplying text and icons, and provides methods that assist the derived adapters in overriding ItemProviderAdapter.collectNewChildDescriptors(java.util.Collection, java.lang.Object).

addModelGroupChildParameters

protected void addModelGroupChildParameters(java.util.Collection<java.lang.Object> newChildDescriptors,
                                            org.eclipse.emf.ecore.EReference feature,

This is a convenience method for creating CommandParameters for simple type definitions of zero, one, two, or all of three varieties (atomic, list, and union), and adding them to a newChildDescriptors collection. The simple type definition objects are to be added to the specified feature of parent. The varieties for which to create simple type definitions and command parameters are specified by the three boolean arguments, atomic, list, and union.

isGlobal

protected boolean isGlobal(java.lang.Object parent)

This determines whether an object represents a global element, based on the type of its parent.

createAttributeDeclaration

protected XSDAttributeDeclaration createAttributeDeclaration(XSDConcreteComponent parent)

This creates an object of type XSDAttributeDeclaration with a name that is unique globally (compared to other global attribute declarations) or locally (compared to sibling attribute declarations and children of sibling attribute groups), depending on the type of the specified parent. The created object will be initialized to resolve to itself and to have the string type definition.

Note: in determining local uniqueness, we do not consider any referenced uses of the parent group or type elsewhere in the schema.

getAttributeSiblings

protected java.util.Collection<? extends XSDAttributeUse> getAttributeSiblings(XSDConcreteComponent parent)

This gathers and returns the siblings by stepping up through any attribute group definitions to the top-most parent attribute definition or complex type definition, and returning the attribute uses for it. Returns null if there is no such parent.

isUniqueAttributeDeclarationName

protected boolean isUniqueAttributeDeclarationName(java.lang.String localName,
                                                   java.lang.String targetNamespace,
                                                   java.util.Collection<? extends XSDAttributeUse> attributeUses)

This tests whether the combination of given localName and targetNamespace is shared by an attribute declaration of an attribute use in the given collection. Returns false if so, true otherwise. Note that this method is tolerant of nulls: a result of true is returned if attributeUse is null, and two null strings are considered equal.

createElementDeclaration

protected XSDElementDeclaration createElementDeclaration(XSDConcreteComponent parent)

This creates an object of type XSDElementDeclaration with a name that is unique globally or locally, depending on the type of the specified parent. The created object will be initialized to resolve to itself and to have the string type definition.

Note: in determining local uniqueness, we do not consider any referenced uses of the parent group or type elsewhere in the schema.

getTopModelGroup

protected XSDModelGroup getTopModelGroup(XSDConcreteComponent parent)

If the specified parent is a model group, this finds and returns the top-most model group above it (within the same complex type or model group definition). Otherwise, returns null.

isUniqueElementDeclarationName

protected boolean isUniqueElementDeclarationName(java.lang.String localName,
                                                 java.lang.String targetNamespace,
                                                 XSDModelGroup modelGroup,
                                                 java.util.HashSet<XSDModelGroup> visited)

This tests whether the combination of given localName and targetNamespace is shared by an element declaration in the given model group or a model group under it. Returns false if so, true otherwise. Note that this method is tolerant of nulls: a result of true is returned if modelGroup is null, and two null strings are considered equal. Also, note that the visited argument is used to avoid an infinite recursion situation, and should be null when the method is initially called.

createAttributeGroupDefinition

protected XSDAttributeGroupDefinition createAttributeGroupDefinition(XSDConcreteComponent parent)

This creates an object of type XSDAttributeGroupDefinition with a name that is unique globally, and that resolves to itself. The created object is to be added under the specified parent.

This creates an object of type XSDModelGroupDefinition with a name that is unique globally, and that resolves to itself. The created object is to be added under the specified parent.

protected XSDComplexTypeDefinition createComplexTypeDefinition(XSDConcreteComponent parent)

This creates an object of type XSDComplexTypeDefinition with a name that is unique globally, if this is to be a global definition; otherwise, with no name. The created object is to be added under the specified parent.

createSimpleTypeDefinition

protected XSDSimpleTypeDefinition createSimpleTypeDefinition(XSDConcreteComponent parent)

This creates an object of type XSDSimpleTypeDefinition with a name that is unique globally, if this is to be a global definition; otherwise, with no name. The created object is to be added under the specified parent.

createIdentityConstraintDefinition

protected XSDIdentityConstraintDefinition createIdentityConstraintDefinition(XSDConcreteComponent parent)

This creates an object of type XSDIdentityConstraintDefinition with a name that is unique globally. The created object is to be added under the specified parent.

createNotationDeclaration

                                             boolean isReference)

This creates an object of type XSDAttributeUse containing an object of type XSDAttributeDeclaration -- if isReference is true, the attribute use content will be a new attribute declaration that resolves to attributeDeclaration; otherwise, it will be simply attributeDeclaration itself.

createAttributeGroupDefinitionReference

protected XSDAttributeGroupDefinition createAttributeGroupDefinitionReference(XSDAttributeGroupDefinition attributeGroupDefinition)

This creates an object of type XSDAttributeGroupDefinition that resolves to attributeGroupDefinition.

createParticle

protected XSDParticle createParticle(XSDParticleContent particleContent,
                                     boolean isReference)

This creates an object of type XSDParticle containing an object of type XSDParticleContent -- if either particleContent is an element declaration and isReference is true or particleContent is a model group definition, the particle content will be a new element declaration that resolves to particleContent; otherwise, it will be simply particleContent itself.
