public CRAMFileWriter(OutputStream outputStream,
                      CRAMReferenceSource referenceSource,

                      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

    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

    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.

- Method Detail
  - 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.
