Class XSAttributeChecker

      org.apache.xerces.impl.xs.traversers.XSAttributeChecker

    public class XSAttributeChecker

extends java.lang.Object

Class `XSAttributeCheck` is used to check the validity of attributes appearing in the schema document. It - reports an error for invalid element (invalid namespace, invalid name) - reports an error for invalid attribute (invalid namespace, invalid name) - reports an error for invalid attribute value - return compiled values for attriute values - provide default value for missing optional attributes - provide default value for incorrect attribute values But it's the caller's responsibility to check whether a required attribute is present. Things need revisiting: - Whether to return non-schema attributes/values - Do we need to update NamespaceScope and ErrorReporter when reset()? - Should have the datatype validators return compiled value - use symbol table instead of many hashtables

Constructor Detail

### XSAttributeChecker

    public XSAttributeChecker(XSDHandler schemaHandler)

Method Detail

### reset

    public void reset(SymbolTable symbolTable)

### checkAttributes

    public java.lang.Object[] checkAttributes(org.w3c.dom.Element element,
                                              boolean isGlobal,
                                              org.apache.xerces.impl.xs.traversers.XSDocumentInfo schemaDoc)

  Check whether the specified element conforms to the attributes restriction an array of attribute values is returned. the caller must call `returnAttrArray` to return that array.

  Parameters:
    `element` - which element to check
    `isGlobal` - whether a child of <schema> or <redefine>
    `schemaDoc` - the document where the element lives in
  Returns:
    an array containing attribute values

### checkAttributes

    public java.lang.Object[] checkAttributes(org.w3c.dom.Element element,
                                              boolean isGlobal,
                                              org.apache.xerces.impl.xs.traversers.XSDocumentInfo schemaDoc,
                                              boolean enumAsQName)

  Check whether the specified element conforms to the attributes restriction an array of attribute values is returned. the caller must call `returnAttrArray` to return that array. This method also takes an extra parameter: if the element is "enumeration", whether to make a copy of the namespace context, so that the value can be resolved as a QName later.

  Parameters:
    `element` - which element to check
    `isGlobal` - whether a child of <schema> or <redefine>
    `schemaDoc` - the document where the element lives in
    `enumAsQName` - whether to tread enumeration value as QName
  Returns:
    an array containing attribute values

### checkNonSchemaAttributes

### normalize

### getAvailableArray

    protected java.lang.Object[] getAvailableArray()

### returnAttrArray

    public void returnAttrArray(java.lang.Object[] attrArray,
                                org.apache.xerces.impl.xs.traversers.XSDocumentInfo schemaDoc)

### resolveNamespace

    public void resolveNamespace(org.w3c.dom.Element element,
                                 org.w3c.dom.Attr[] attrs,
