Detailed Description

Matrix item class.

Library: ilvadvgdt

Use this class to define a matrix item as a double-precision floating-point value.

See also: IlvFilledDoubleMatrixItem, IlvMatrix.

Accessors\nAccessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods <tt>IlvValueInterface::queryValue()</tt>, <tt>IlvValueInterface::queryValues()</tt>, <tt>IlvValueInterface::changeValue()</tt>, <tt>IlvValueInterface::changeValues()</tt>.\n\n\nThis class inherits the accessors of its superclass \c IlvAbstractMatrixItem and adds the following ones:

Name	Type	Equivalent methods
`label`	String	`getLabel()`, `setLabel()`
`value`	Double	`getDouble()`, `setDouble()`
`format`	String	`getFormat()`

Constructor & Destructor Documentation

◆ IlvDoubleMatrixItem()

IlvDoubleMatrixItem::IlvDoubleMatrixItem ( IlDouble value )

Constructor.

Initializes a new instance of the class IlvDoubleMatrixItem.

Parameters

value The double-precision floating-point value encapsulated by the item.

Member Function Documentation

◆ copy()

virtual IlvAbstractMatrixItem* IlvDoubleMatrixItem::copy ( ) const

virtual

Copies this object.

Allocates and returns a copy of this object.

Returns: A copy of the object.

See also: IlvPredefinedMatrixItemIOMembers().

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvFilledDoubleMatrixItem.

◆ getDouble()

IlDouble IlvDoubleMatrixItem::getDouble ( ) const

Returns the double-precision floating-point value stored in the matrix item.

Returns: The double-precision floating-point value stored in this matrix item.

See also: setDouble().

◆ getFormat()

virtual const char* IlvDoubleMatrixItem::getFormat ( ) const

virtual

Returns the format used to display the double-precision floating-point value.

The default implementation returns f. You can override this member function in a subclass to modify the format.

Returns: The format used to display the double-precision floating-point value of the matrix item.

◆ getLabel()

virtual const char* IlvDoubleMatrixItem::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.

See also: setLabel().

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvFilledDoubleMatrixItem.

◆ setDouble()

void IlvDoubleMatrixItem::setDouble ( IlDouble value )

Sets the double-precision floating-point value stored in the matrix item.

Parameters

value The new double-precision floating-point value.

See also: getDouble().

◆ setLabel()

virtual void IlvDoubleMatrixItem::setLabel	(	const char *	label,
		IlBoolean	copy = `IlTrue`
	)

virtual

Sets the label of the matrix item.

Parameters

label	The label of the matrix item.
copy	Specifies 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`.

See also: getLabel().

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvFilledDoubleMatrixItem.

◆ write()

virtual void IlvDoubleMatrixItem::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.

See also: DeclareMatrixItemInfoRO(), DeclareMatrixItemInfo(), IlvPredefinedMatrixItemIOMembers().

Reimplemented from IlvAbstractMatrixItem.

Reimplemented in IlvFilledDoubleMatrixItem.
