Collection of FitsHeaderEntries that have been read from the data blocks so far. This will be cleared once a complete FitsHeader is formed.

public List<FitsHeaderEntry> CurrentEntries { get; }

Header

If not null, this will contain the FitsHeader that was read from the data blocks. Note, no more data can be written to this writer after the header is set.

public FitsHeader? Header { get; }

Property Value

FitsHeader

Methods

AddHeaderReader(IFitsHeaderReader)

Registers a new IFitsHeaderReader instance to receive the parsed FitsHeader.

public void AddHeaderReader(IFitsHeaderReader headerReader)

Parameters

headerReader IFitsHeaderReader

Exceptions

ArgumentNullException

WriteDataBlock(FitsDataBlock)

public override void WriteDataBlock(FitsDataBlock dataBlock)

Parameters

dataBlock FitsDataBlock

The data block containing FitsHeaderEntries

Exceptions

ArgumentNullException

Thrown if dataBlock is null.

FitsModelException
