Method Detail

setWorker

public void setWorker(OpenOfficeMetadataWorker worker)

init

public void init()

Initialises the bean by establishing an UNO connection

Overrides:

init in class AbstractMappingMetadataExtracter

isConnected

public boolean isConnected()

Specified by:

isConnected in interface OpenOfficeMetadataWorker

Returns:

Returns true if a connection to the Uno server could be established

isSupported

public boolean isSupported(String sourceMimetype)

Perform the default check, but also check if the OpenOffice connection is good.

Specified by:

isSupported in interface MetadataExtracter

Overrides:

isSupported in class AbstractMappingMetadataExtracter

Parameters:

sourceMimetype - the document mimetype

Returns:

Returns true if the mimetype is supported, otherwise false.

See Also:

AbstractMappingMetadataExtracter.setSupportedMimetypes(Collection)

extractRaw

public Map<String,Serializable> extractRaw(org.alfresco.service.cmr.repository.ContentReader reader)
                                    throws Throwable

Override to provide the raw extracted metadata values. An extracter should extract as many of the available properties as is realistically possible. Even if the default mapping doesn't handle all properties, it is possible for each instance of the extracter to be configured differently and more or less of the properties may be used in different installations.

Raw values must not be trimmed or removed for any reason. Null values and empty strings are

• Null: Removed
• Empty String: Passed to the OverwritePolicy
• Non Serializable: Converted to String or fails if that is not possible

Properties extracted and their meanings and types should be thoroughly described in the class-level javadocs of the extracter implementation, for example:

 editor: - the document editor        -->  cm:author
 title:  - the document title         -->  cm:title
 user1:  - the document summary
 user2:  - the document description   -->  cm:description
 user3:  -
 user4:  -
 

Specified by:

extractRaw in interface OpenOfficeMetadataWorker

Specified by:

extractRaw in class AbstractMappingMetadataExtracter

Parameters:

reader - the document to extract the values from. This stream provided by the reader must be closed if accessed directly.

Returns:

Returns a map of document property values keyed by property name.

Throws:

Throwable - All exception conditions can be handled.
