public XFMLTopicMapReader(java.lang.String url)
                   throws java.net.MalformedURLException

Creates an XFML reader.

Parameters:

url - The URL of the XFML document.

Throws:

java.net.MalformedURLException

XFMLTopicMapReader

public XFMLTopicMapReader(java.io.Reader reader,
                          LocatorIF base_address)

Creates an XFML reader bound to the reader given in the arguments.

Parameters:

reader - The reader from which the XFML document is to be read.

base_address - The base address to be used for resolving relative references.

XFMLTopicMapReader

public XFMLTopicMapReader(java.io.InputStream stream,
                          LocatorIF base_address)

Creates an XFML reader bound to the input stream given in the arguments.

Parameters:

stream - The input stream from which the topic map is to be read.

base_address - The base address to be used for resolving relative references.

XFMLTopicMapReader

public XFMLTopicMapReader(java.io.File file)
                   throws java.io.IOException

Method Detail

getStoreFactory

public TopicMapStoreFactoryIF getStoreFactory()

PUBLIC: Gets the store factory which will be used to create stores.

setStoreFactory

public void setStoreFactory(TopicMapStoreFactoryIF store_factory)

PUBLIC: Sets the store factory which will be used to create stores.

Default: InMemoryStoreFactory

Parameters:

store_factory - The store factory to use. If the parameter is null the default store factory will be used.

read

public TopicMapIF read()
                throws java.io.IOException

Description copied from interface: TopicMapReaderIF

PUBLIC: Reads the next topic map available from some implicit, implementation dependent source.

A topic map source may contain multiple topic maps. The read method returns the next topic map that is available from that source. null is returned when there are no more topic maps available. In a sense this is iterator-like behaviour.

Specified by:

read in interface TopicMapReaderIF

Returns:

The next topic map read from the source; an object implementing TopicMapIF. null is returned when there are no more topic maps available from the source.

Throws:

java.io.IOException - Thrown if reading the source fails.

readAll

public java.util.Collection readAll()
                             throws java.io.IOException

Description copied from interface: TopicMapReaderIF

PUBLIC: Reads all the topic map available from some implicit, implementation dependent source.

A topic map source may contain multiple topic maps. The readAll method returns a collection contain all the topic maps available from the source.

Specified by:

readAll in interface TopicMapReaderIF

Returns:

A collection containing all the topic maps read from the source; objects implementing TopicMapIF.

Throws:

java.io.IOException - Thrown if reading the source fails.

importInto

public void importInto(TopicMapIF topicmap)
                throws java.io.IOException

Description copied from interface: TopicMapImporterIF

PUBLIC: Imports an implicitly designated topic map into the given topic map.

Specified by:

importInto in interface TopicMapImporterIF

Parameters:

topicmap - The topic map into which the import will be done; an object implementing TopicMapIF.

Throws:

java.io.IOException

configureXMLReaderFactory

protected void configureXMLReaderFactory(ConfiguredXMLReaderFactory cxrfactory)

Specified by:

configureXMLReaderFactory in class AbstractXMLFormatReader
