Note that this creates a new class for each instance, so it has much higher memory overhead than using `BaseObjectProxy` directly. If you know what special dunder methods you need then it is preferable to use `BaseObjectProxy` directly and add them to a subclass as needed. If you only need `__iter__()` support for backwards compatibility then use `ObjectProxy` instead. csNi}t|}tt|}t|rd|vrt|d<d|vr$d|vr$t|d<d|vr0d|vr0t|d<d|vrrr?rrrtype)rwrapped namespace wrapped_attrs class_attrsr=rr r r_s: zAutoObjectProxy.__new__cCs~t|}tt|}t|jrd|vrt|_n t|ddtur$t|dt |jdr2d|vr1t |_ n t|ddt ur?t|dt |jdrMd|vrLt |_ n t|ddt urZt|dt |jdrhd|vrgt|_n t|ddturut|dt |jdrd|vrt|_n t|ddturt|dt |jdrd|vrt|_n t|ddturt|dt |jdrd|vrt|_n t|ddturt|dt |jd rd |vrt|_n t|d dturt|d t |jd rd |vrt|_n t|d dturt|d t |jd r d |vr t|_nt|d dturt|d t |jd r-d |vr+t|_dSdSt|d dtur=t|d dSdS) zAdjusts special dunder methods on the class as needed based on the wrapped object, when `__wrapped__` is changed. rANrr&r(r*r-r/r2r7r:r<)rErCrBrDrr#rAgetattrdelattrhasattrr$rr'r&r)r(r+r*r.r-r0r/r5r2r9r7r;r:r>r<)r rrIr r r __wrapped_setattr_fixups__s                       z*AutoObjectProxy.__wrapped_setattr_fixups__)rrrrrrMr!r r rr r?Us 6r?csPeZdZdZdddfdd Zdddfdd Zd Zd d Zd d ZZ S)LazyObjectProxyzhAn object proxy which can generate/create the wrapped object on demand when it is first needed.
