Public Methods

Method	Description
CreateWithBounds ( Stream BaseStream, long LowerBound, long UpperBound, bool CanWrite = null ) : SliceStream	Creates a SliceStream specifying a start offset and a end offset.
CreateWithLength ( Stream BaseStream, long ThisStart, long ThisLength = -1, bool CanWrite = null ) : SliceStream	Creates a SliceStream specifying a start offset and a length.
Read ( byte buffer, int offset, int count ) : int	Read a chunk from this SliceStream and move its cursor after that chunk. Only will be able to read inside the bounds of this Slice. It won't change the ParentStream cursor.
Seek ( long offset, SeekOrigin origin ) : long	Seeks the SliceStream without altering the original Stream.
SetLength ( long value ) : void	Not implemented.
Write ( byte buffer, int offset, int count ) : void	Writes a chunk from this SliceStream and move its cursor after that chunk. Only will be able to write inside the bounds of this Slice. It won't change the ParentStream cursor.

Protected Methods

Method	Description
SliceStream ( Stream BaseStream, long ThisStart, long ThisLength = -1, bool CanWrite = null, bool AllowSliceOutsideHigh = true ) : System	Creates a SliceStream specifying a start offset and a length. Please use CreateWithLength or CreateWithBounds to initialite the object.

Method Details

CreateWithBounds() static public method

Creates a SliceStream specifying a start offset and a end offset.

static public CreateWithBounds ( Stream BaseStream, long LowerBound, long UpperBound, bool CanWrite = null ) : SliceStream
BaseStream	Stream	Parent Stream
LowerBound	long
UpperBound	long
CanWrite	bool	Determines if the Stream will be writtable.
return	SliceStream

CreateWithLength() static public method

Creates a SliceStream specifying a start offset and a length.

static public CreateWithLength ( Stream BaseStream, long ThisStart, long ThisLength = -1, bool CanWrite = null ) : SliceStream
BaseStream	Stream	Base Stream
ThisStart	long	Starting Offset
ThisLength	long	Length of the Slice
CanWrite	bool	Determines if the Stream will be writtable.
return	SliceStream

Read() public method

Read a chunk from this SliceStream and move its cursor after that chunk. Only will be able to read inside the bounds of this Slice. It won't change the ParentStream cursor.

public Read ( byte buffer, int offset, int count ) : int
buffer	byte	ByteArray to write to
offset	int	Offset of the ByteArray to write to
count	int	Number of bytes to read
return	int

Seek() public method

Seeks the SliceStream without altering the original Stream.

public Seek ( long offset, SeekOrigin origin ) : long
offset	long	Offset to seek
origin	SeekOrigin	Origin for the seeking
return	long

SetLength() public method

Not implemented.

public SetLength ( long value ) : void
value	long
return	void

SliceStream() protected method

Creates a SliceStream specifying a start offset and a length. Please use CreateWithLength or CreateWithBounds to initialite the object.

protected SliceStream ( Stream BaseStream, long ThisStart, long ThisLength = -1, bool CanWrite = null, bool AllowSliceOutsideHigh = true ) : System
BaseStream	Stream	Base Stream
ThisStart	long	Starting Offset
ThisLength	long	Length of the Slice
CanWrite	bool	Determines if the Stream will be writtable.
AllowSliceOutsideHigh	bool
return	System

Write() public method

Writes a chunk from this SliceStream and move its cursor after that chunk. Only will be able to write inside the bounds of this Slice. It won't change the ParentStream cursor.

public Write ( byte buffer, int offset, int count ) : void
buffer	byte	ByteArray to read from
offset	int	Offset of the ByteArray to read from
count	int	Number of bytes to write
return	void
