value - the value to set for the property.

getResource

public org.xmldb.api.base.Resource getResource(java.lang.String uri,
                                               java.lang.String username,
                                               java.lang.String password)

Gets the specified resource from the database. This implementation does not support authentication.

Specified by:

getResource in interface org.sixdml.SixdmlDatabase

Parameters:

uri - the name or path to the resource to obtain.

username - The username to use for authentication to the database or null if the database does not support authentication.

password - The password to use for authentication to the database or null if the database does not support authentication.

Returns:

the requested resource.

getSupportedIndexTypes

public org.sixdml.dbmanagement.SixdmlIndexType[] getSupportedIndexTypes()

Gets the types of index that are supported by the this database.

Returns:

an array of SixdmlIndexTypes which the database supports.

Throws:

org.xmldb.api.base.XMLDBException - if an error occurs.

getSupportedTransformTypes

public org.sixdml.transform.SixdmlTransformType[] getSupportedTransformTypes()

Gets the types of transforms that are supported by the this database.

Returns:

an array of SixdmlTransformTypes which the database supports.

Throws:

getConformanceLevel

public java.lang.String getConformanceLevel()

Returns the XML:DB API Conformance level for the implementation. This can be used by client programs to determine what functionality is available to them.

Specified by:

getConformanceLevel in interface org.xmldb.api.base.Database

Returns:

XML:DB API conformance level for this implementation.

acceptsURI

public boolean acceptsURI(java.lang.String uri)

Determines whether this Database implementation can handle the URI. It should return true if the Database instance knows how to handle the URI and false otherwise. In this implementation it checks to see if the target of the URI exists in the DB, this may not be what is meant for this method to do.

Specified by:

acceptsURI in interface org.xmldb.api.base.Database

Parameters:

uri - the URI to check for.

Returns:

true if the URI can be handled, false otherwise

Retrieves a Collection instance based on the URI provided in the uri parameter. This implementation does not support authentication.

Specified by:

getCollection in interface org.xmldb.api.base.Database

Parameters:

uri - the URI to use to locate the collection.

username - The username to use for authentication to the database or null if the database does not support authentication.

password - The password to use for authentication to the database or null if the database does not support authentication.

Returns:

the requested vollection.

Throws:

org.xmldb.api.base.XMLDBException - if no such collection exists

getService

public org.xmldb.api.base.Service getService(java.lang.String name,
                                             java.lang.String version)

Returns all the top level documents and collections in the database.

Specified by:

getService in interface org.sixdml.SixdmlDatabase

Parameters:

name - the name of the service to return.

version - the version number of the service to return.

Returns:

an array containing the names of all the top level /** Returns a Service instance for the requested service name and version. If no Service exists for those parameters a null value is returned. The only valid name and version number for this implementation are "XSLT" and "1.0" respectively.

getServices

public org.xmldb.api.base.Service[] getServices()

Provides a list of all services known to the collection. If no services are known an empty list is returned.

Specified by:

getServices in interface org.sixdml.SixdmlDatabase

Returns:

An array of registered Service implementations.
