) of text in this
Editable with a copy of the slice start…end
from
source
. The destination slice may be empty, in which case
the operation is an insertion, or the source slice may be empty,
in which case the operation is a deletion.
Before the change is committed, each filter that was set with
Editable.setFilters(a_vcard.android.text.InputFilter[])
is given the opportunity to modify the
source
text.
If source
is Spanned, the spans from it are preserved into the Editable.
Existing spans within the Editable that entirely cover the replaced
range are retained, but any that were strictly within the range
that was replaced are removed. As a special case, the cursor
position is preserved even when the entire range where it is
located is replaced.
