공개 메소드들

메소드	설명
AppendAsync ( IFdbTransaction trans, Slice data ) : System.Threading.Tasks.Task	Append the contents of data onto the end of the blob.
Delete ( IFdbTransaction trans ) : void	Delete all key-value pairs associated with the blob.
FdbBlob ( FdbSubspace subspace ) : FoundationDB.Client	Create a new object representing a binary large object (blob). Only keys within the subspace will be used by the object. Other clients of the database should refrain from modifying the subspace.
GetSizeAsync ( IFdbReadOnlyTransaction trans ) : Task	Get the size (in bytes) of the blob.
ReadAsync ( IFdbReadOnlyTransaction trans, long offset, int n ) : Task	Read from the blob, starting at offset, retrieving up to n bytes (fewer then n bytes are returned when the end of the blob is reached).
TruncateAsync ( IFdbTransaction trans, long newLength ) : System.Threading.Tasks.Task	Change the blob length to newLength, erasing any data when shrinking, and filling new bytes with 0 when growing.
WriteAsync ( IFdbTransaction trans, long offset, Slice data ) : System.Threading.Tasks.Task	Write data to the blob, starting at and overwriting any existing data at that location. The length of the blob is increased if necessary.
