JavaBlock
JavaBlock[
expr
]
causes all new Java objects returned to
Mathematica
during the evaluation of
expr
to be released when
expr
finishes. It is an error to refer to such an object after
JavaBlock
ends.
MORE INFORMATION
To use
JavaBlock
, you first need to load
J/Link
using
Needs
["JLink`"]
.
JavaBlock
is a way to mark a set of objects as temporary so they can be automatically cleaned up when the block of code ends.
JavaBlock
affects only new objects, not additional references to ones that have previously been seen.
If a
JavaBlock
returns a single
JavaObject
as a result, that object will not be released.
