Method Detail

accept

public void accept(IDataImplVisitor aVisitor)
            throws XmlException

Specified by:

accept in interface IImpl

Throws:

XmlException

getAttributeData

public IAnyTypeData getAttributeData(java.lang.String aNamespace,
                                     java.lang.String aLocalName)

Description copied from interface: IImpl

Gets the data object of an attribute.

Specified by:

getAttributeData in interface IImpl

Parameters:

aNamespace - (required).

aLocalName - (required).

Returns:

(optional).

isDefault

public boolean isDefault()

Description copied from interface: IImplWithText

Checks if the data implementation is a default value or if a value was assigned explicitly.

Specified by:

isDefault in interface IImplWithText

Returns:

Returns true iff the data implementation is a default value.

isNil

public boolean isNil()

Description copied from interface: IImpl

Indicates if the data implementation was assigned "nil".

Specified by:

isNil in interface IImpl

Returns:

Returns true iff the data implementation was assigned "nil".

iterAttributes

public java.util.Iterator iterAttributes(java.lang.String aNamespace,
                                         java.lang.String aName)

Description copied from interface: IDataImpl

Iterates the attribute data objects for the specified namespace and name.

Specified by:

iterAttributes in interface IDataImpl

Parameters:

aNamespace - (optional).

aName - (optional).

Returns:

(required). An iterator of IAnyTypeData.

iterChildren

public java.util.ListIterator iterChildren()

Description copied from interface: IImpl

Iterates the children.

Specified by:

iterChildren in interface IImpl

Returns:

(required). A list iterator of IImpl.

iterElementData

public java.util.ListIterator iterElementData(java.lang.String aNamespace,
                                              java.lang.String aLocalName)

Description copied from interface: IImpl

Iterates the data objects for the specified namespace and element name.

Specified by:

iterElementData in interface IImpl

Parameters:

aNamespace - (required).

aLocalName - (required).

Returns:

(required). An iterator of IAnyTypeData.

getPrefixToNamespaceMapping

public java.util.Map getPrefixToNamespaceMapping()

Description copied from interface: IImpl

Gets the prefix to namespace mapping.

Specified by:

getPrefixToNamespaceMapping in interface IImpl

Returns:

(required).

hasTextContent

public boolean hasTextContent()

Description copied from interface: IImplWithText

Checks if the implementation has textual content. This method is used to decide if a default value should be used or not.

Attribute implementations will always return true because attributes take their default values only if they are not present in the instance.

Element implementation will return true iff their text content is null or equal to the empty string. In other words the default value of an element is used when the element is empty. (cf. the note at W3C XML-Schema-Structure specification section 3.1.1).

Specified by:

hasTextContent in interface IImplWithText

Returns:

Returns true iff there is textual content.

restoreTextContent

public void restoreTextContent(ITextContentMemento aMemento)

Specified by:

restoreTextContent in interface IImplWithText

saveTextContent

public ITextContentMemento saveTextContent()

Specified by:

saveTextContent in interface IImplWithText

getTextContent

public java.lang.String getTextContent()

Description copied from interface: IImplWithText

Gets the textual content. The textual content corresponds to the lexical value of a data object. For data implementations of attributes the string that is assigned to the attribute is returned. For data implementations of elements with simple content the string value that is assigned to the simple content is returned. If the simple content is empty then the empty string is returned.

Specified by:

getTextContent in interface IImplWithText

Returns:

(required).

setTextContent

public void setTextContent(ITextContentProvider aTextContentProvider)

Description copied from interface: IImplWithText

Sets the textual content by specifiying a provider for lazy evaluation.

Specified by:

setTextContent in interface IImplWithText

Parameters:

aTextContentProvider - (required).

setTextContent

public void setTextContent(java.lang.String aString)

Description copied from interface: IImplWithText

Sets the textual content. The textual content corresponds to the lexical value of a data object.

Specified by:

setTextContent in interface IImplWithText

Parameters:

aString - (required).
