Public Member Functions

virtual size64_t

sizeOf (bool fDeep=false) const

Return an estimate as to the byte size of the object.

The shallow size should not include the cost of referenced managed objects, or non-fixed dynamically allocated memory. That for a given object it is assumed that a call to this method will always return the same value when the shallow size is requested.

The deep size should be the shallow size plus the size of any referenced objects. Unlike the shallow size the deep size may change over time. The default implementation provided by Object will traverse the object graph of all managed objects which it references and include their sizes in the computed deep size. In general it is sufficient to simply delegate to super::sizeOf(true) for deep calculations.

For classes implemented via class_spec, a variant of this method will be automatically produced which will utilize sizeof(*this) to compute the shallow size, and super::sizeOf(true) to compute the deep size. As such it is generally not necessary to provide custom implmenetations of this method.

Parameters:

fDeep

true if the size should include the size of referenced objects

Returns:: the approximate shallow byte size of the object
