CRAMFileWriter

public CRAMFileWriter(OutputStream outputStream,
 CRAMReferenceSource referenceSource,
 SAMFileHeader samFileHeader,
 String fileName)

Create a CRAMFileWriter on an output stream. Requires input records to be presorted to match the sort order defined by the input samFileHeader.

Parameters:

outputStream - where to write the output. Can not be null.

referenceSource - reference source. Can not be null.

samFileHeader - SAMFileHeader to be used. Can not be null. Sort order is determined by the sortOrder property of this arg.

fileName - used for display in error messages

Throws:

IllegalArgumentException - if the outputStream, referenceSource or samFileHeader are null

CRAMFileWriter

public CRAMFileWriter(OutputStream outputStream,
 OutputStream indexOS,
 CRAMReferenceSource referenceSource,
 SAMFileHeader samFileHeader,
 String fileName)

Create a CRAMFileWriter and optional index on output streams. Requires input records to be presorted to match the sort order defined by the input samFileHeader.

Parameters:

outputStream - where to write the output. Can not be null.

indexOS - where to write the output index. Can be null if no index is required.

referenceSource - reference source

samFileHeader - SAMFileHeader to be used. Can not be null. Sort order is determined by the sortOrder property of this arg.

fileName - used for display in error messages

Throws:

IllegalArgumentException - if the outputStream, referenceSource or samFileHeader are null

CRAMFileWriter

public CRAMFileWriter(OutputStream outputStream,
 OutputStream indexOS,
 boolean presorted,
 CRAMReferenceSource referenceSource,
 SAMFileHeader samFileHeader,
 String fileName)

Create a CRAMFileWriter and optional index on output streams.

Parameters:

outputStream - where to write the output. Can not be null.

indexOS - where to write the output index. Can be null if no index is required.

presorted - if true records written to this writer must already be sorted in the order specified by the header

referenceSource - reference source

samFileHeader - SAMFileHeader to be used. Can not be null. Sort order is determined by the sortOrder property of this arg.

fileName - used for display in error message display

Throws:

IllegalArgumentException - if the outputStream, referenceSource or samFileHeader are null

CRAMFileWriter

public CRAMFileWriter(CRAMEncodingStrategy encodingStrategy,
 OutputStream outputStream,
 OutputStream indexOS,
 boolean presorted,
 CRAMReferenceSource referenceSource,
 SAMFileHeader samFileHeader,
 String fileName)

Create a CRAMFileWriter and optional index on output streams.

Parameters:

encodingStrategy - encoding strategy to use when writing

outputStream - where to write the output. Can not be null.

indexOS - where to write the output index. Can be null if no index is required.

presorted - if true records written to this writer must already be sorted in the order specified by the header

referenceSource - reference source

samFileHeader - SAMFileHeader to be used. Can not be null. Sort order is determined by the sortOrder property of this arg.

fileName - used for display in error message display

Throws:

IllegalArgumentException - if the outputStream, referenceSource or samFileHeader are null

Method Details

writeAlignment

protected void writeAlignment(SAMRecord alignment)

Write an alignment record.

Specified by:

writeAlignment in class SAMFileWriterImpl

Parameters:

alignment - must not be null and must have a valid SAMFileHeader.

writeHeader

protected void writeHeader(String textHeader)

Description copied from class: SAMFileWriterImpl

Write the header to disk. Header object is available via getHeader().

Specified by:

writeHeader in class SAMFileWriterImpl

Parameters:

textHeader - for convenience if the implementation needs it.

writeHeader

protected void writeHeader(SAMFileHeader header)

Description copied from class: SAMFileWriterImpl

Write the header to disk. Header object is available via getHeader().

IMPORTANT: this method will be abstract once SAMFileWriterImpl.writeHeader(String) is removed.

Note: default implementation uses SAMTextHeaderCodec.encode(java.io.Writer, htsjdk.samtools.SAMFileHeader) and calls SAMFileWriterImpl.writeHeader(String).

Overrides:

writeHeader in class SAMFileWriterImpl

Parameters:

header - object to write.

finish

protected void finish()

Description copied from class: SAMFileWriterImpl

Do any required flushing here.

Specified by:

finish in class SAMFileWriterImpl

getFilename

protected String getFilename()

Description copied from class: SAMFileWriterImpl

For producing error messages.

Specified by:

getFilename in class SAMFileWriterImpl

Returns:

Output filename, or null if there isn't one.
