|---|---|---|
 | PlException()()() |
Initializes a new instance of the Exception class.
|
| PlException(String) |
Initializes a new instance of the Exception class with a specified error message.
|
| PlException(String, Exception) |
Initializes a new instance of the Exception class with a specified error message and a reference to the inner exception that is the cause of this exception.
|
 | PlException(SerializationInfo, StreamingContext) |
Initializes a new instance of the Exception class with serialized data.
|
| PlException(PlTerm) | To catch a exception thrown by prolog For a example see PlException. |
 | Data |
Gets a collection of key/value pairs that provide additional user-defined information about the exception.
(Inherited from Exception.) |
| Equals(Object) | (Inherited from Object.) |
| Finalize()()() |
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.) |
| GetBaseException()()() |
When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.
(Inherited from Exception.) |
| GetHashCode()()() |
Serves as a hash function for a particular type.
(Inherited from Object.) |
| GetObjectData(SerializationInfo, StreamingContext) |
When overridden in a derived class, sets the SerializationInfo with information about the exception.
(Overrides Exception.GetObjectData(SerializationInfo, StreamingContext).) |
| GetType()()() |
Gets the runtime type of the current instance.
(Inherited from Exception.) |
| HelpLink |
Gets or sets a link to the help file associated with this exception.
(Inherited from Exception.) |

Creates a shallow copy of the current Object.
(Inherited from Object.) |
| Message |
Gets a message that describes the current exception.
(Overrides Exception.Message.) |
