CMatrixRow:Empty

The Empty method deletes all members of the CMatrixRow but does not delete the CMatrixRow object.

Syntax

CMatrixRow:Empty()

This deletes all array members without deleting the CMatrixRow object itself. If you delete the CMatrixRow, the object is set to nil and cannot be used again without creating a new instance using new. By calling Empty, the existing CMatrixRow can be used to Set new members, and so forth.

Example

The following script sets 3 members in a new CMatrixRow M, then deletes all members of M:

R = CMatrixRow:new()	-- create a CMatrixRow
R:Set( 127, -63.25 )	-- set member
R:Set( 100, 12.34 )	-- set member
R:Set( 4, -42 )	-- set member
Printf("Members = %d", R:Count() )	-- result: Members = 3
R:Empty()	-- empty the array
Printf("Members = %d", R:Count() )	-- result: Members = 0
