Detailed Description

Input/output class.

Library: ilvmgr

Manager objects and their properties can be read from particular streams. To make it easy to restore a set of IlvGraphic objects, Rogue Wave Views defines the IlvManagerInputFile class. This class is a subtype of IlvInputFile. It adds only manager-specific information to the object description blocks. To read a full Rogue Wave Views file in a given manager, call the member function readAll.

IlvGraphic, IlvManager, IlvManagerOutputFile.

Member Function Documentation

IlvManager* IlvManagerInputFile::getManager

(

)

const

Returns a pointer to the manager reading the objects.

Returns:

A pointer to the manager object in which a file is now being read. This value is updated by the member function readAll.

virtual void IlvManagerInputFile::readAll

(

IlvManager *

manager

)

[virtual]

Reads an object description file.

Reads an Rogue Wave Views object description file and stores the created objects in the manager parameter. It calls the member function readObjects and reads specific object properties, such as object names.

Parameters:

manager

Pointer to the manager in which the graphic objects must be stored.

Reimplemented in IlvGadgetManagerInputFile.

virtual void IlvManagerInputFile::readLayer

(

int

layer

)

[virtual]

Reads the properties of a layer.

Parameters:

layer

The index of the layer.

virtual IlvGraphic* IlvManagerInputFile::readObject

(

)

[virtual]

Reads a graphic object.

Overloads the member function of IlvInputFile to add specific layer information in the description block of each object. Is called internally by readAll and should never be called directly by the programmer.

Returns:

A pointer to the graphic object read.

Reimplemented from IlvInputFile.

Reimplemented in IlvGadgetManagerInputFile.

virtual void IlvManagerInputFile::readView	(	IlUInt	currentNViews,
		IlvView **	currentViews
	)			[virtual]

Reads transformer information for a view.

Reads specific information for one view (name and transformer). If a view with the same name is found in the array of current views, the transformer is set on this view.

Parameters:

	currentNViews	The number of views in the array.
	currentViews	The array of current views.

virtual const char* IlvManagerInputFile::typeOf

(

)

const [virtual]

Returns the name of this class.

Returns:

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

Reimplemented from IlvInputFile.

Reimplemented in IlvGadgetManagerInputFile.
