Python unwrap Examples

Example #1

File: test_warmstate.py Project: alkorzt/pypy

def test_unwrap():
    S = lltype.GcStruct('S')
    p = lltype.malloc(S)
    po = lltype.cast_opaque_ptr(llmemory.GCREF, p)
    assert unwrap(lltype.Void, BoxInt(42)) is None
    assert unwrap(lltype.Signed, BoxInt(42)) == 42
    assert unwrap(lltype.Char, BoxInt(42)) == chr(42)
    assert unwrap(lltype.Float, BoxFloat(42.5)) == 42.5
    assert unwrap(lltype.Ptr(S), BoxPtr(po)) == p

Example #2

File: virtualizable.py Project: enyst/plexnet

 def write_boxes(virtualizable, boxes):
     i = 0
     for FIELDTYPE, fieldname in unroll_static_fields:
         x = unwrap(FIELDTYPE, boxes[i])
         setattr(virtualizable, fieldname, x)
         i = i + 1
     for ARRAYITEMTYPE, fieldname in unroll_array_fields:
         lst = getattr(virtualizable, fieldname)
         for j in range(getlength(lst)):
             x = unwrap(ARRAYITEMTYPE, boxes[i])
             setarrayitem(lst, j, x)
             i = i + 1
     assert len(boxes) == i + 1

Example #3

File: virtualizable.py Project: enyst/plexnet

     # for debugging
     i = 0
     for FIELDTYPE, fieldname in unroll_static_fields:

Example #4

File: warmspot.py Project: alkorzt/pypy

 def __init__(self, argboxes):
     # accepts boxes as argument, but unpacks them immediately
     # before we raise the exception -- the boxes' values will
     # be modified in a 'finally' by restore_patched_boxes().
     from pypy.jit.metainterp.warmstate import unwrap
     for i, name, ARG in portalfunc_ARGS:
         v = unwrap(ARG, argboxes[i])
         setattr(self, name, v)

Example #5

     funcargs = ()
     assert len(argboxes) == args_n
     i = 0
     for ARG in argsiter:

Example #8

 def setfield(objbox, valuebox):
     obj = objbox.getref(TYPE)
     value = unwrap(T, valuebox)
     setattr(obj, fieldname, value)

Example #9

 def setarrayitem(arraybox, ibox, valuebox):
     array = arraybox.getref(ARRAY)
     i = ibox.getint()
     value = unwrap(TYPE, valuebox)
     array.ll_setitem_fast(i, value)
