# Changed Features

This chapter describes the features that were changed in this release of the DEF application programming interface.

| Reader Class Routines

## Reader Class Routines

The following syntax was added to the listed reader class routines.

### defiBlockage

Description:

setMask(int maskColor)
| Adds the color mask number to the blockage. The default value is 0.

mask() | Returns the color mask number of the blockage.

For more information, see "defiBlockage" in the DEF C/C++ Programming Interface Open Licensing Program).

| Returns the layer masks by index. maskShift(0) will return the right-most digit.

For more information, see "defiComponent" in the DEF C/C++ Programming Interface Open Licensing Program).
