checkConnection(RepositoryConnection c) |
protected java.lang.String |
checkEncoding(java.lang.String encoding)
Verifies an encoding string,
if not supported by JVM default is used, UTF-8.

get(Document doc,
java.io.OutputStream os,
RepositoryConnection c)
Does param checks for subclasses
|
protected java.lang.String |
getClassNameSuffix()
Sub classes should element this method to return their class name suffix for SAX output
|
protected java.lang.String |
getDocumentGetQuery()
Returns an SQL query that could select a document using its id.
|
boolean |
isDefault()
Returns whether it is a default repository for an application.
|
protected void |
loadBaseConfiguration(org.apache.avalon.framework.configuration.Configuration configuration)
Loads base configuration common to all repositories.
|
java.io.InputStream |
openStream(Document doc,
java.lang.String encoding,
RepositoryConnection c)
Does param checks for subclasses
|
void |
optimize()
Utility method for repository maintenance,
normally used to optimize indices of Lucene based repositories
It is the responsibility of the Repository to ensure that
unnecessary optimizations are not performed when this method
is called.
|
void |
setIsDefault(boolean b)
Sets the isDefault flag for the repository
|
void |
toSAX(ParsableDocument doc,

protected void loadBaseConfiguration(org.apache.avalon.framework.configuration.Configuration configuration) throws org.apache.avalon.framework.configuration.ConfigurationException
configuration
- The configuration object
The parameter required are an id for the repository, an optional attribute
indicating if the repository is the default within a document base is also handled
but the default if not specified will be false.configuration
- The configuration for this repository (based on a xml file).
Sample configuration entry:
<sdx:repository sdx:type = "FS" sdx:id = "myRepoId" baseDirectory = "baseDirName" depth = "2" extent = "50"/>
org.apache.avalon.framework.configuration.ConfigurationException
we should link to this in the future when we have better documentation capabilities
