Constructor & Destructor Documentation

arlo.NesterWavFileMetaData.NesterWavFileMetaData

(

)

Default Constructor.

arlo.NesterWavFileMetaData.NesterWavFileMetaData

(

AudioFile

audioFile

)

Constructor from an initialized AudioFile.

Parameters

audioFile

An initialized AudioFile

Returns

initialized NesterWavFileMetaData

Member Function Documentation

boolean arlo.NesterWavFileMetaData.BatchSaveMetaData	(	int	mediaFileID,
		PreparedStatement	stmtInsertMetadata
	)

Save MetaData as a 'Batch'.

This saves MetaData in a batch using an SQL Prepared Statement.

Parameters

mediaFileID	The Db id of the mediafile corresponding to this Metadata
stmtInsertMetadata	A prepared INSERT statement. See arlo.NesterAudioFile.saveNewAudioFilesToDb Of the form "INSERT INTO tools_mediafilemetadata (mediaFile_id, name, value, userEditable) VALUES (?, ?, ?, ?)"

Returns

Boolean - true if success, false on error

boolean arlo.NesterWavFileMetaData.getNesterWavFileMetaData	(	int	audioFileID,
		Connection	connection,
		HashMap< String, Boolean >	fieldNames
	)

boolean arlo.NesterWavFileMetaData.getNesterWavFileMetaData	(	HashMap< String, Vector< String >>	sourceData,
		HashMap< String, Boolean >	fieldNames
	)

Parse the Metadata from a Map of values.

Parameters

sourceData	A key/value map of raw metadata values, where 'value' is a Vector where each entry represent a record in the database (there will usually be only one record per key in the database, so this Vector will usually be length = 1.
fieldNames	If not null, then require and parse only these keys.

Returns

True on success, False if any errors occur, including missing required keys.

static HashMap<String, Vector<String> > arlo.NesterWavFileMetaData.getSourceData ( int  audioFileID, Connection  connection  )

static

Get all of the raw metadata entries from the database for an Audio File.

Parameters

audioFileID	Database Id of the AudioFile for which to retrieve data.
connection	An opened database connection.

Returns

null if any error, otherwise a key/value map, where keys are the metadata names and values are Vectors, where each entry represents a database record for that key.
