XMLMetadataResultSet

public XMLMetadataResultSet(ResultSet rs,

Method Detail

close

public void close()
           throws MetadataStoreException

Description copied from interface: MetadataResultSet

Must be invoked after using to close underlying resources, e.g. SQL ResultSets.

Specified by:

close in interface MetadataResultSet<T extends MetadataRecord>

Throws:

MetadataStoreException

getRecord

public T getRecord()
                                   throws MetadataStoreException

Description copied from interface: MetadataResultSet

Returns the MetadataRecord at the current cursor position.

Specified by:

getRecord in interface MetadataResultSet<T extends MetadataRecord>

Returns:

record at the current position, never null

Throws:

MetadataStoreException

skip

public void skip(int rows)
          throws MetadataStoreException

Specified by:

skip in interface MetadataResultSet<T extends MetadataRecord>

Throws:

MetadataStoreException

getRemaining

public int getRemaining()
                 throws MetadataStoreException

Specified by:

getRemaining in interface MetadataResultSet<T extends MetadataRecord>

Returns:

Throws:

MetadataStoreException

next

public boolean next()
             throws MetadataStoreException

Description copied from interface: MetadataResultSet

Moves the cursor down one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

Specified by:

next in interface MetadataResultSet<T extends MetadataRecord>

Returns:

true, if the cursor was moved down one row, false otherwise (no rows left)

Throws:

MetadataStoreException

getRecord

protected abstract T getRecord(XMLStreamReader xmlReader)
