Constructor Detail

StoreImpl

public StoreImpl(java.lang.String database,
         java.lang.String username,
         java.lang.String password,
         java.lang.String storeParentPath,
         java.lang.String dataCollectionName)
          throws XBRLException

Initialise the database connection.

Parameters:

database - Database name

username - Username of the database user

password - Password of the database user

storeParentPath - The full path to the container collection, which is the collection that will hold the data collection when it are created.

dataCollectionName - The name of the data collection.

Throws:

XBRLException

Method Detail

getConnection

public DBConnection getConnection()

Returns:

the database connection or null if there is none.

close

public void close()
           throws XBRLException

Close the data store. Throws XBRLException if the data store cannot be closed.

Specified by:

close in interface Store

Overrides:

close in class BaseStoreImpl

Throws:

XBRLException

See Also:

Store.close()

delete

public void delete()
            throws XBRLException

Description copied from interface: Store

Close and then delete the data store. This method must be synchronized.

Specified by:

delete in interface Store

Throws:

XBRLException - if the data store cannot be deleted.

See Also:

Store.delete()

getSize

public int getSize()
            throws XBRLException

Specified by:

getSize in interface Store

Returns:

the number of fragments in the data store.

Throws:

XBRLException - if the number of fragments cannot be determined.

See Also:

Store.persist(XML)

persist

public void persist(XML xml)
             throws XBRLException

Add a fragment to the DTS. Sets the fragment builder to null because it is no longer required, stores the fragment data and metadata in the data store, sets the store property in the fragment.

Specified by:

persist in interface Store

Parameters:

xml - The fragment to be added to the DTS store.

Throws:

XBRLException - if the fragment cannot be added to the store (eg: because one with the same index is already in the store).

hasXMLResource

public boolean hasXMLResource(java.lang.String index)
                       throws XBRLException

Test if a store contains a specific fragment, as identified by its index.

Specified by:

hasXMLResource in interface Store

Parameters:

index - The index of the fragment to test for.

Returns:

true iff the store contains a fragment with the specified fragment index.

Throws:

XBRLException - If the test cannot be conducted.

getXMLResource

public <F extends XML> F getXMLResource(java.lang.String index)
                             throws XBRLException

Retrieves a fragment from an XBRL API data store. The fragment will be created as a fragment of the original fragment type but will be returned as a straight fragment.

Specified by:

getXMLResource in interface Store

Parameters:

index - The index of the fragment.

Returns:

The fragment corresponding to the specified index or null if the fragment is not in the store.

Throws:

XBRLException - if the fragment cannot be retrieved.

remove

public void remove(java.lang.String index)
            throws XBRLException

Remove a fragment from the DTS. If a fragment with the same ID does not already exist in the DTs then no action is required.

Specified by:

remove in interface Store

Parameters:

index - The index of the fragment to be removed from the DTS store.

Throws:

XBRLException - if the fragment cannot be removed from the store.

remove

public void remove(XML xml)
            throws XBRLException

Description copied from interface: Store

Remove a XML resource from the underlying data structure. If a XML resource with the same ID does not already exist in the data store then no action is required.

Specified by:

remove in interface Store

Overrides:

remove in class BaseStoreImpl

Parameters:

xml - The XML resource to remove.

Throws:

XBRLException - if the XML resource cannot be removed from the store.

See Also:

Store.remove(XML)

queryForXMLResources

public <F extends XML> java.util.List<F> queryForXMLResources(java.lang.String query)
                                                   throws XBRLException

Description copied from interface: Store

Run a query against the collection of all fragments in the store. Implementations of this method must be synchronized.

Specified by:

queryForXMLResources in interface Store

Parameters:

query - The XQuery query to run against the set of fragments. Any occurrences of the string #roots# in a query will be deemed to be a marker for the root elements of the fragments in an XML database collection and it will be substituted with the necessary expression to identify those roots in the data store.

Returns:

a list of matching fragments or the empty list if no matching fragments exist.

Throws:

XBRLException - if the query cannot be executed.

See Also:

Store.queryForXMLResources(String)

queryCount

public long queryCount(java.lang.String query)
                throws XBRLException

Description copied from interface: Store

This method must be synchronised

Specified by:

queryCount in interface Store

Parameters:

query - The XQuery to run. Any occurrences of the string #roots# in a query will be deemed to be a marker for the root elements of the fragments in an XML database collection and it will be substituted with the necessary expression to identify those roots in the data store.

Returns:

a count of the number of results returned by the query.

Throws:

XBRLException - if the query cannot be executed.

See Also:

Store.queryCount(String)

queryForIndices

public java.util.Set<java.lang.String> queryForIndices(java.lang.String query)

query - The XQuery query to run against the set of fragments. Any occurrences of the string #roots# in a query will be deemed to be a marker for the root elements of the fragments in an XML database collection and it will be substituted with the necessary expression to identify those roots in the data store. The query MUST return a sequence of XML resource metadata root elements matching the query. Otherwise, results from the query will be unpredictable.

Returns:

a set of the indices of XML resources matching the query.

Throws:
