C# Class SIL.Utils.Logger

Logs stuff to a file created in c:\Documents and Settings\Username\Local Settings\Temp\Companyname\Productname\Log.txt

This class also has a rudimentary implementation of IStream. The only really implemented method is IStream.Write, the other methods of this interface are no-ops or throw a NotImplementedException.

Inheritance: IFWDisposable, IStream

Méthodes publiques

Méthode	Description
CheckDisposed ( ) : void	Check to see if the object has been disposed. All public Properties and Methods should call this before doing anything else.
Clone ( IStream &ppstm ) : void	Creates a new stream object with its own seek pointer that references the same bytes as the original stream.
Commit ( int grfCommitFlags ) : void	Ensures that any changes made to a stream object that is open in transacted mode are reflected in the parent storage.
CopyTo ( IStream pstm, long cb, IntPtr pcbRead, IntPtr pcbWritten ) : void	Copies a specified number of bytes from the current seek pointer in the stream to the current seek pointer in another stream.
Dispose ( ) : void	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. Must not be virtual.
Init ( string projectName ) : void	Creates the logger. The logging functions can't be used until this method is called.
LockRegion ( long libOffset, long cb, int dwLockType ) : void	Restricts access to a specified range of bytes in the stream.
Read ( byte pv, int cb, IntPtr pcbRead ) : void	Reads a specified number of bytes from the stream object into memory starting at the current seek pointer.
Revert ( ) : void	Discards all changes that have been made to a transacted stream since the last M:System.Runtime.InteropServices.ComTypes.IStream.Commit(System.Int32) call.
Seek ( long dlibMove, int dwOrigin, IntPtr plibNewPosition ) : void	Changes the seek pointer to a new location relative to the beginning of the stream, to the end of the stream, or to the current seek pointer.
SetSize ( long libNewSize ) : void	Changes the size of the stream object.
ShutDown ( ) : void	Shut down the logger. The logging functions can't be used after this method is called.
Stat ( System &pstatstg, int grfStatFlag ) : void	Retrieves the structure for this stream.
UnlockRegion ( long libOffset, long cb, int dwLockType ) : void	Removes the access restriction on a range of bytes previously restricted with the method.
Write ( byte pv, int cb, IntPtr pcbWritten ) : void	Writes a specified number of bytes into the stream object starting at the current seek pointer.
WriteError ( Exception e ) : void	Writes an exception and its stack trace to the log. This method will do nothing if Init() is not called first.
WriteError ( string msg, Exception e ) : void	Writes msg and an exception and its stack trace to the log. This method will do nothing if Init() is not called first.
WriteEvent ( string message ) : void	Writes an event to the logger. This method will do nothing if Init() is not called first.

Private Methods

Méthode	Description

Method Details

CheckDisposed() public méthode

Check to see if the object has been disposed. All public Properties and Methods should call this before doing anything else.

public CheckDisposed ( ) : void
Résultat	void

Clone() public méthode

Creates a new stream object with its own seek pointer that references the same bytes as the original stream.

public Clone ( IStream &ppstm ) : void
ppstm	IStream	When this method returns, contains the new stream object. /// This parameter is passed uninitialized.
Résultat	void

Commit() public méthode

Ensures that any changes made to a stream object that is open in transacted mode are reflected in the parent storage.

public Commit ( int grfCommitFlags ) : void
grfCommitFlags	int	A value that controls how the changes for the stream /// object are committed.
Résultat	void

CopyTo() public méthode

Copies a specified number of bytes from the current seek pointer in the stream to the current seek pointer in another stream.

public CopyTo ( IStream pstm, long cb, IntPtr pcbRead, IntPtr pcbWritten ) : void
pstm	IStream	A reference to the destination stream.
cb	long	The number of bytes to copy from the source stream.
pcbRead	System.IntPtr	On successful return, contains the actual number of bytes /// read from the source.
pcbWritten	System.IntPtr	On successful return, contains the actual number of bytes /// written to the destination.
Résultat	void

Dispose() public méthode

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

Must not be virtual.

public Dispose ( ) : void
Résultat	void

Init() public static méthode

Creates the logger. The logging functions can't be used until this method is called.

public static Init ( string projectName ) : void
projectName	string	Name of the project that can be used (and certainly will /// be) to generate a unique log file name.
Résultat	void

LockRegion() public méthode

Restricts access to a specified range of bytes in the stream.

public LockRegion ( long libOffset, long cb, int dwLockType ) : void
libOffset	long	The byte offset for the beginning of the range.
cb	long	The length of the range, in bytes, to restrict.
dwLockType	int	The requested restrictions on accessing the range.
Résultat	void

Read() public méthode

Reads a specified number of bytes from the stream object into memory starting at the current seek pointer.

public Read ( byte pv, int cb, IntPtr pcbRead ) : void
pv	byte	When this method returns, contains the data read from the stream. /// This parameter is passed uninitialized.

pcbRead	System.IntPtr	A pointer to a ULONG variable that receives the actual number /// of bytes read from the stream object.
Résultat	void
