Method Detail

exportData

public void exportData(org.apache.commons.configuration2.HierarchicalConfiguration<org.apache.commons.configuration2.tree.ImmutableNode> exportConfig)
                throws ConceptDatabaseConnectionException,
                       DataExportException

Description copied from interface: DataExporter

Export data from the database to an external location.

Parameters:

exportConfig - Export subconfiguration.

Throws:

ConceptDatabaseConnectionException

DataExportException

setConnection

public void setConnection(org.apache.commons.configuration2.HierarchicalConfiguration<org.apache.commons.configuration2.tree.ImmutableNode> connectionConfiguration)
                   throws ConceptDatabaseConnectionException

Description copied from interface: DatabaseConnected

Requires the implementing service provider to check if the given connection is supported and, if so, to use it for later method calls. Please not that this kind of state requires caution in case of multithreading.

If the provider cannot serve to given connection configuration, it is required to throw a ConceptDatabaseConnectionException. This serves as the indication that the provider is not applicable for the required connection type. Typically, it will then just be omitted by its service.

Parameters:

connectionConfiguration - The connection details, e.g. HTTP, BOLT or file-based connection.

Throws:

ConceptDatabaseConnectionException - If the provider does not support the passed connection configuration.
