factory

protected StorageManagerFactory factory

The factory for which the reader reads the document. The factory is used to verify whether the document is compatible, and is used to instantiate objects that depend on factory information (such as schemes)

Constructor Detail

StorageReader

public StorageReader(StorageManagerFactory factory,
                     InputSource source)

Constructor.

Parameters:

factory - the factory for which to read the storage configuration

source - to the xml document.

Since:

MMBase-1.7

Method Detail

getStorageManagerClass

public Class getStorageManagerClass()
                             throws StorageConfigurationException

Attempt to load a StorageManager class, using the classname as given in the configuration. The method verifies whether the instantiated class is of the correct version.

Returns:

the storage manager Class, or null if none was configured

Throws:

StorageConfigurationException - if the factory version did not match, or the class configured is invalid

getSearchQueryHandlerClasses

public List getSearchQueryHandlerClasses()
                                  throws StorageConfigurationException

Attempt to obtain a list of SearchQueryHandler classes, using the classname as given in the configuration.

Returns:

A List of Class objects, each being the SearchQueryHandler class, or an empty list if none was configured

Throws:

StorageConfigurationException - if the class configured is invalid

getAttributes

public Map getAttributes()

Reads all attributes from the reader and returns them as a map. This include options, as well as the following special attributes:

• option-disallowed-fields-case-sensitive : has the Boolean value TRUE if disallowed fields are case sensitive (default FALSE)

Returns:

attributes as a map

getDisallowedFields

public Map getDisallowedFields()

Returns all disallowed fields and their possible alternate values. The fields are returned as name-value pairs, where the disallowedfieldname is the key, and the alternate name is the value (null if no name is given).

Returns:

disallowed fields as a map

getTypeMappings

public List getTypeMappings()

Returns all type mappings. The mappings are returned in the order that they were given in the reader. Calling code should sort this list if they want to use TypoMapping fuzzy matching.

Returns:

a List of TypeMapping objects
