Field Detail

### fName

    public java.lang.String fName

### fTargetNamespace

    public java.lang.String fTargetNamespace

### fAttributeWC

    public XSWildcardDecl fAttributeWC

### fIDAttrName

    public java.lang.String fIDAttrName

### fAnnotation

    public XSAnnotationImpl fAnnotation

### fAttrUses

    protected XSObjectListImpl fAttrUses

Constructor Detail

### XSAttributeGroupDecl

    public XSAttributeGroupDecl()

Method Detail

### addAttributeUse

    public java.lang.String addAttributeUse(XSAttributeUseImpl attrUse)

### getAttributeUse

    public org.apache.xerces.xs.XSAttributeUse getAttributeUse(java.lang.String namespace,
                                                               java.lang.String name)

### removeProhibitedAttrs

    public void removeProhibitedAttrs()

### validRestrictionOf

    public java.lang.Object[] validRestrictionOf(java.lang.String typeName,
                                                 XSAttributeGroupDecl baseGroup)

  Check that the attributes in this group validly restrict those from a base group. If an error is found, an Object[] is returned. This contains the arguments for the error message describing the error. The last element in the array (at index arr.length - 1) is the the error code. Returns null if there is no error. REVISIT: is there a better way of returning the appropriate information for the error?
  Parameters:
    `typeName` - the name of the type containing this attribute group, used for error reporting purposes
    `baseGroup` - the XSAttributeGroupDecl that is the base we are checking against

### reset

    public void reset()
