const

returns the target base installed product, also known as the distribution or platform.

returns 0 if there is no base installed product in the pool.

Note

this method requires the target to be loaded, otherwise it will return 0 as no product is found.

if you require some base product attributes when the target is not loaded into the pool, see targetDistribution , targetDistributionRelease and distributionVersion that obtain the data on demand from the installed product information.
