Foam::disabledBoolList
|
|

Description
|
|
A trivial structure to use as a boolList replacement when testing
|
|
compilation without using the [] accessors.
|
|
|
|
Example,
|
|
\code
|
|
const disableBoolList blockedFace;
|
|
...
|
|
|
|
if (blockedFace.test(facei)) ... // Good
|
|
if (blockedFace[facei]) ... // Compile error
|
|
\endcode
