    Constructors

    RAMOutputStream()

    Construct an empty output buffer.

    Declaration
    public RAMOutputStream()

    RAMOutputStream(RAMFile)

    A memory-resident IndexOutput implementation.

    Note

    This API is for internal purposes only and might change in incompatible ways in the next release.

    Declaration
    public RAMOutputStream(RAMFile f)
    Parameters
    Type Name Description
    RAMFile f

    Properties

    Checksum

    Returns the current checksum of bytes written so far

    Declaration
    public override long Checksum { get; }
    Property Value
    Type Description
    long
    Overrides
    IndexOutput.Checksum

    Length

    Gets or Sets the file length. By default, this property's setter does nothing (it's optional for a Directory to implement it). But, certain Directory implementations (for example FSDirectory) can use this to inform the underlying IO system to pre-allocate the file to the specified size. If the length is longer than the current file length, the bytes added to the file are undefined. Otherwise the file is truncated.

    Declaration
    public override long Length { get; set; }
    Property Value
    Type Description
    long
    Overrides
    IndexOutput.Length

    Position

    Returns the current position in this file, where the next write will occur.

    This was getFilePointer() in Lucene.
    Declaration
    public override long Position { get; }
    Property Value
    Type Description
    long
    Overrides
    IndexOutput.Position
    See Also
    Seek(long)

    Methods

    Dispose(bool)

    Closes this stream to further operations.

    Declaration
    protected override void Dispose(bool disposing)
    Parameters
    Type Name Description
    bool disposing
    Overrides
    IndexOutput.Dispose(bool)

    Flush()

    Forces any buffered output to be written.

    Declaration
    public override void Flush()
    Overrides
    IndexOutput.Flush()

    GetSizeInBytes()

    Returns byte usage of all buffers.

    Declaration
    public virtual long GetSizeInBytes()
    Returns
    Type Description
    long

    Reset()

    Resets this to an empty file.

    Declaration
    public virtual void Reset()

    Seek(long)

    Sets current position in this file, where the next write will occur.

    Declaration
    [Obsolete("(4.1) this method will be removed in Lucene 5.0")]
    public override void Seek(long pos)
    Parameters
    Type Name Description
    long pos
    Overrides
    IndexOutput.Seek(long)
    See Also
    Position

    WriteByte(byte)

    Writes a single byte.

    The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.
    Declaration
    public override void WriteByte(byte b)
    Parameters
    Type Name Description
    byte b
    Overrides
    DataOutput.WriteByte(byte)
    See Also
    ReadByte()

    WriteBytes(byte[], int, int)

    Writes an array of bytes.

    Declaration
    public override void WriteBytes(byte[] b, int offset, int len)
    Parameters
    Type Name Description
    byte[] b

    the bytes to write

    int offset

    the offset in the byte array

    int len
    Overrides
    DataOutput.WriteBytes(byte[], int, int)
    See Also
    ReadBytes(byte[], int, int)

    WriteTo(DataOutput)

    Copy the current contents of this buffer to the named output.

    Declaration
    public virtual void WriteTo(DataOutput @out)
    Parameters
    Type Name Description
    DataOutput out

    WriteTo(byte[], int)

    Copy the current contents of this buffer to output byte array

    Declaration
    public virtual void WriteTo(byte[] bytes, int offset)
    Parameters
    Type Name Description
    byte[] bytes
    int offset

    Implements
