Detailed Description

Input/output class.

Library: ilvmgr

Manager objects and their properties can be saved from particular streams. To simplify the saving of a set of IlvGraphic objects, Rogue Wave Views defines the IlvManagerOutputFile class. This class is a subtype of IlvOutputFile. It adds only manager-specific information to the object description blocks. To save the objects of a manager, call the member function saveAll of an instance of IlvManagerOutputFile with an array of objects.

Constructor & Destructor Documentation

IlvManagerOutputFile::IlvManagerOutputFile	(	ILVSTDPREF ostream &	stream,
		const IlvManager *	mgr = 0
	)

Constructor.

The constructor is the same as for the IlvOutputFile class.

Parameters

stream

A valid output stream in which you are ready to write.

Member Function Documentation

const IlvManager* IlvManagerOutputFile::getManager

(

)

const

Returns a pointer to the manager saving the objects.

Returns

A pointer to the manager object from which to get the objects to be saved. This value is updated by the member function saveAll.

IlBoolean IlvManagerOutputFile::isSavingLayers

(

)

const

Status of the ability to save layers.

Returns

IlTrue if the manager can save layers or IlFalse if it cannot.

IlBoolean IlvManagerOutputFile::isSavingViews

(

)

const

Status of the ability to save views.

Returns

IlTrue if the manager can save views or IlFalse if it cannot.

virtual void IlvManagerOutputFile::saveAll ( const IlvManager *  manager, IlUInt  count = 0, IlvGraphic *const *  objects = 0  )

virtual

Writes an object description file.

Writes a complete Rogue Wave Views object description file with the full description of the count objects found in the objects array.

Parameters

manager	The IlvManager instance holding the graphic objects.
count	The number of elements in the array objects.
objects	The array of graphic objects.

void IlvManagerOutputFile::saveLayers

(

IlBoolean

s

)

Turns on or off the ability to save layers.

Parameters

s	If IlTrue, the manager saves layers. Otherwise, it does not.

void IlvManagerOutputFile::saveViews

(

IlBoolean

s

)

Turns on or off the ability to save views.

Parameters

s	If IlTrue, the manager saves the views. Otherwise, it does not.

virtual const char* IlvManagerOutputFile::typeOf ( ) const

virtual

Returns the name of the class.

Returns

A pointer to the string "<code>IlvManagerOutput</code>".

Reimplemented in IlvGadgetManagerOutputFile.

virtual void IlvManagerOutputFile::writeObject ( const IlvGraphic *  object )

virtual

Save a graphic object.

Writes the exact description of a graphic object in the output stream. It overloads the member function of the IlvOutputFile class to add manager-specific information for this object, such as layer information. Do not directly call this member function. The saving mechanism is internally performed by saveAll.

Parameters

object

The graphic object.

Reimplemented from IlvOutputFile.
