Methods

  Name Description
Public method AdjustCurrentParameter Update the current parameter, either forward or backward, by the specified amount.
Public method Close Closes the method tip and clears the MethodData object.
Public method Dismiss Dismisses the method tip from view.
Public method Dispose Frees any allocations made just before the MethodData object is destroyed.
Public method Equals Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetContextStream Converts the current context span to a file position and length.
Public method GetCurMethod Returns the currently visible method signature.
Public method GetCurrentParameter Returns the current parameter being edited in the specified method signature.
Public method GetHashCode Serves as the default hash function. (Inherited from Object.)
Public method GetMethodText Returns the specified text for the specified method signature.
Public method GetOverloadCount Returns the number of method signatures that can be shown.
Public method GetParameterCount Returns the number of parameters available for the specified method signature.
Public method GetParameterText Returns the specified parameter text for the specified method signature.
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method NextMethod Moves to the next method signature and returns the index of the current method signature.
Public method OnDismiss Called after the method tip is removed from view.
Public method PrevMethod Moves to the previous method signature and returns the index of the current method signature.
Public method Refresh Displays the method tip with the given method signatures.
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Public method UpdateView Updates the method tip display.

Remarks

This class is used by the Source class to implement the IntelliSense method tip operation. This class presents the tool tip and manages it as the user types the various parameters. This class uses a Methods object to contain all of the appropriate method signatures for the method currently being typed. This Methods object is filled in by the parser when the parsing reason MethodTip is given.

Notes to Implementers

The base class already implements most of everything needed to support the IntelliSense method tip operation, so there is little need to derive from this class. If your language requires more specialized formatting of method data, then you must derive a class from the MethodData class and override the GetMethodText method. You must also override the CreateMethodData method in the Source class to create an instance of your version of the MethodData class.

This class interacts with the Methods class to obtain information on how to format method signatures. Specifically, this class consults the properties, OpenBracket, CloseBracket, Delimiter, TypePrefixed, TypePrefix, and TypePostfix to format the method signatures in the method tip. Since all of this information is obtained through the Methods class, you should not need to override the MethodData class.

Notes to Callers

This class is instantiated in the CreateMethodData method in the Source class.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
