                            throws Exception

Retrieves the attributes of a given artifact (CI or a Relationship).

Specified by:

getAttributes in class MetaData

Parameters:

artifactType - determines the type of artifact, which attributes we want. Accepts either IdMLConstants.ARTIFACT_CI or IdMLConstants.ARTIFACT_RELATIONSHIP.

classType - the type of the artifact, which attributes we want.

Returns:

a Vector containing the CI/Relationship attributes.

Throws:

Exception - if a problem occurs.

getCdmVersion

public String getCdmVersion()
                     throws Exception

Retrieves the version of the Common Data Model, which meta-data is extracted.

Specified by:

getCdmVersion in class MetaData

Returns:

a string representing the CDM version. Its format is '<version>.<release>.<modifier>'.

Throws:

Exception - if a problem occurs.

getTypes

public Map<String,Object> getTypes(String artifactType)
                            throws Exception
