How does 'InBagFraction' work in Treebagger?

I'm confused on how the 'InBagFraction' parameter works in Treebagger. With the defaults of 'SampleWithReplacement' as on and 'InBagFraction' as 1, that doesn't really seem to follow the idea of sample with replacement. Does the default value 1 mean that the entire input data is used to grow each tree? Does 0.5 mean only half of the input data (randomly selected) is used to grow each tree?

Thanks!
