CMatrix:Empty
The Empty method deletes all members of the matrix but does not delete the CMatrix object.
|
CMatrix:Empty() |
This deletes all matrix members without deleting the CMatrix object itself. If you delete the CMatrix, the object is set to nil and cannot be used again without creating a new instance using new. By calling Empty, the existing CMatrix can be used to Set new members, and so forth.
The following script fragment sets 3 members in a new CMatrix M, then deletes all members of M:
|
M = CMatrix:new() |
-- create a CMatrix |
|
M:Set( 127, 6000, -63.25 ) |
-- set member |
|
M:Set( 100, 5, 12.34 ) |
-- set member |
|
M:Set( 4, 600, -42 ) |
-- set member |
|
Printf("Members = %d", M:Count()) |
-- result: Members = 3 |
|
M:Empty() |
-- empty the matrix |
|
Printf("Members = %d", M:Count()) |
-- result: Members = 0 |
|
M:delete() |
-- if finished with M, clean up memory |
