Constructor & Destructor Documentation

IlvIntMatrixItem::IlvIntMatrixItem

(

IlInt

value

)

Constructor.

Initializes a new instance of the class IlvIntMatrixItem.

Parameters:

value

The integer value encapsulated by the item.

Member Function Documentation

virtual IlvAbstractMatrixItem* IlvIntMatrixItem::copy

(

)

const [virtual]

Copies this object.

Allocates and returns a copy of this object.

Returns:

A copy of the object.

IlvPredefinedMatrixItemIOMembers.

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvFilledIntMatrixItem.

IlInt IlvIntMatrixItem::getInt

(

)

const

Returns the value currently stored in this matrix item.

Returns:

The value currently stored in this matrix item.

See also:

setInt

virtual const char* IlvIntMatrixItem::getLabel

(

)

const [virtual]

Returns the label that identifies this matrix item.

Returns:

The label that identifies this matrix item. The returned string must not be deleted or modified.

setLabel

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvFilledIntMatrixItem.

static IlvAbstractMatrixItem* IlvIntMatrixItem::readItem	(	IlvInputFile &	file,
		IlvDisplay *	display
	)			[static]

Reads an object description from a file.

Reads an object description from the file input. It reads the information that was saved by the member function write to be able to create a new instance of this object. Usually, because of the availability of the constructor that expects an IlvInputFile, readItem should be equivalent to :

 IlvAbstractMatrixItem*
 MyClass::readItem(IlvInputFile& file, IlvDisplay* display)
 {
     return new MyClass(file, display);
 }

Parameters:

	file	The file to be read from.
	display	The display used to create the object.

DeclareMatrixItemInfoRO, DeclareMatrixItemInfo, IlvPredefinedMatrixItemIOMembers.

Warning:

[note] The readItem method is not capitalized like other static methods so that it is consistent with the write method.

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvFilledIntMatrixItem.

void IlvIntMatrixItem::setInt

(

IlInt

value

)

Sets the integer value of the matrix item.

Parameters:

value

The new integer value.

See also:

getInt

virtual void IlvIntMatrixItem::setLabel	(	const char *	label,
		IlBoolean	copy = IlTrue
	)			[virtual]

Sets the label of the matrix item.

Parameters:

	label	The label of the matrix item.
	copy	A Boolean value specifying whether a label should be copied. If the value is IlFalse, then you must allocate some memory for the label because in any case the label characters are deleted from the memory by the IlvAbstractMatrixItem.

getLabel

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvFilledIntMatrixItem.

virtual void IlvIntMatrixItem::write

(

IlvOutputFile &

file

)

const [virtual]

Writes an object description to a file.

Writes out, in a file, the object description. This description contains all the information necessary to create an exact copy of this object by means of the member function readItem.

Parameters:

file

The name of the file to be written to.
