Constructor Detail

AISBinaryDataSource

public AISBinaryDataSource(AISControl aisControl,
                           AISDataBlock sisterDataBlock)

Method Detail

getModuleVersion

public int getModuleVersion()

Description copied from class: BinaryDataSource

Get a version number for the module.

This is different to the version number in the main file header and allows individual modules to update their format and maintain backwards compatibility with old data

Specified by:

getModuleVersion in class BinaryDataSource

Returns:

integer module version number

getModuleHeaderData

public byte[] getModuleHeaderData()

Specified by:

getModuleHeaderData in class BinaryDataSource

Returns:

Additional information (e.g. a control structure for a detector) to be stored in the Module Specific Control structure

getStreamName

public java.lang.String getStreamName()

Specified by:

getStreamName in class BinaryDataSource

Returns:

Stream name to be stored in the file header

getStreamVersion

public int getStreamVersion()

Specified by:

getStreamVersion in class BinaryDataSource

Returns:

Stream version name to be stored in the Module Specific Control structure

newFileOpened

public void newFileOpened(java.io.File outputFile)

Description copied from class: BinaryDataSource

Called from the BinaryOutputStream whenever a new output file is opened.

Specified by:

newFileOpened in class BinaryDataSource

Parameters:

outputFile - file information.

saveData

public void saveData(PamDataUnit pamDataUnit)

Description copied from class: BinaryDataSource

Save data into the binary stream

Specified by:

saveData in class BinaryDataSource

sinkData

public PamDataUnit sinkData(BinaryObjectData binaryObjectData,
                            BinaryHeader bh,
                            int moduleVersion)

Description copied from class: BinaryDataSource

Convert data read back in in viewer mode into the correct type of PamDataUnit.

DO NOT add this unit directly to the datablock, but pass it back to the calling process which will add it to the datablock if necessary.

Specified by:

sinkData in class BinaryDataSource

Parameters:

binaryObjectData - Binary data read back from a file.

bh - binary header from start of file.

Returns:

the PamDataUnit created from these data

sinkModuleFooter

public ModuleFooter sinkModuleFooter(BinaryObjectData binaryObjectData,
                                     BinaryHeader bh,
                                     ModuleHeader moduleHeader)

Description copied from class: BinaryDataSource

Do something with module footer information

Specified by:

sinkModuleFooter in class BinaryDataSource

Parameters:

binaryObjectData - data for the module header.

bh - Binary header information

sinkModuleHeader

public ModuleHeader sinkModuleHeader(BinaryObjectData binaryObjectData,
                                     BinaryHeader bh)

Description copied from class: BinaryDataSource

Do something with module header information

Specified by:

sinkModuleHeader in class BinaryDataSource

Parameters:

binaryObjectData - data for the module header.

bh - Binary header information
