Constructors
Declared in <bdlcc_sharedobjectpool.h>
Create an object pool that dispenses shared pointers to TYPE. When the pool is depleted, it increases its capacity according to the optionally specified growBy value. If growBy is positive, the pool always increases by at least growBy. If growBy is negative, the amount of increase begins at -growBy and then grows geometrically up to an implementation-defined maximum. The optionally specified objectCreator is called whenever objects must be constructed. If objectCreator is not specified and the parameterized CREATOR is the default type (that is, ObjectPoolFunctors::DefaultCreator), a function that calls the default constructor of TYPE with placement new, passing this pool's allocator if TYPE uses allocator, is used. If the parameterized CREATOR is some other type, and objectCreator is not specified, the default value of the CREATOR type is used. The optionally specified objectResetter is invoked with a pointer to an object of TYPE when the object is returned to the pool. It must reset the object into a valid state for reuse. If objectResetter is not specified, a default RESETTER object is used. Optionally specify a basic allocator to supply memory. If basicAllocator is 0, the currently installed default allocator is used. The behavior is undefined if growBy is 0.

SharedObjectPool(
int growBy = -1,
bslma::Allocator* basicAllocator = 0);Same as the default constructor, using the specified objectCreator.

SharedObjectPool(
CREATOR const& objectCreator,
bslma::Allocator* basicAllocator = 0);Same as the preceding overload, using the specified growBy.
SharedObjectPool(
CREATOR const& objectCreator,
int growBy,
bslma::Allocator* basicAllocator = 0);Same as the preceding overload, using the specified objectResetter.
