:mrdocs:

In‐place `SharedPtrRep` implementation for a managed object of `TYPE`.

== Synopsis

Declared in `<bslma_sharedptrinplacerep.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class TYPE>
class SharedPtrInplaceRep
    : public xref:BloombergLP/bslma/SharedPtrRep.adoc[SharedPtrRep]
----

== Description

This class provides a concrete implementation of the `SharedPtrRep` protocol for "in‐place" instances of the parameterized `TYPE`. Upon destruction of this object, the destructor of `TYPE` is invoked.

| Name| Description
| xref:BloombergLP/bslma/SharedPtrInplaceRep/2constructor.adoc[`SharedPtrInplaceRep`]         [.small]#[constructor]#
| Create an in‐place representation constructed from `args`.
| xref:BloombergLP/bslma/SharedPtrRep/acquireRef.adoc[`acquireRef`] 
| Atomically acquire a shared reference to the shared object referred to by this representation. The behavior is undefined unless `0 < numReferences()`.
| xref:BloombergLP/bslma/SharedPtrRep/acquireWeakRef.adoc[`acquireWeakRef`] 
| Atomically acquire a weak reference to the shared object.
| xref:BloombergLP/bslma/SharedPtrInplaceRep/disposeObject.adoc[`disposeObject`]  [.small]#[virtual]#
| Destroy the in‐place object managed by this representation.
| xref:BloombergLP/bslma/SharedPtrInplaceRep/disposeRep.adoc[`disposeRep`]  [.small]#[virtual]#
| Deallocate the memory associated with this representation object.
| xref:BloombergLP/bslma/SharedPtrInplaceRep/getDeleter.adoc[`getDeleter`]  [.small]#[virtual]#
| Return a null pointer; in‐place representations never store a deleter.
| xref:BloombergLP/bslma/SharedPtrRep/hasUniqueOwner.adoc[`hasUniqueOwner`] 
| Return `true` if there is only one shared reference and no weak references to the object referred to by this representation, and `false` otherwise.
| xref:BloombergLP/bslma/SharedPtrRep/incrementRefs.adoc[`incrementRefs`] 
| Atomically increment the number of shared references.
| xref:BloombergLP/bslma/SharedPtrRep/numReferences.adoc[`numReferences`] 
| Return a "snapshot" of the current number of shared references to the shared object referred to by this representation object.
| xref:BloombergLP/bslma/SharedPtrRep/numWeakReferences.adoc[`numWeakReferences`] 
| Return a "snapshot" of the current number of weak references to the shared object referred to by this representation object.
| xref:BloombergLP/bslma/SharedPtrInplaceRep/originalPtr.adoc[`originalPtr`]  [.small]#[virtual]#
| Return the (untyped) address of the modifiable (in‐place) object referred to by this representation object.
| xref:BloombergLP/bslma/SharedPtrInplaceRep/ptr.adoc[`ptr`] 
| Return the address of the modifiable (in‐place) object referred to by this representation object.
| xref:BloombergLP/bslma/SharedPtrRep/releaseRef.adoc[`releaseRef`] 
| Atomically release a shared reference to the shared object.
| xref:BloombergLP/bslma/SharedPtrRep/releaseWeakRef.adoc[`releaseWeakRef`] 
| Atomically release a weak reference to the shared object.
| xref:BloombergLP/bslma/SharedPtrRep/resetCountsRaw.adoc[`resetCountsRaw`] 
| Reset the shared and weak reference counts to the specified values.
| xref:BloombergLP/bslma/SharedPtrRep/tryAcquireRef.adoc[`tryAcquireRef`] 
| Try to atomically acquire a shared reference to the shared object.
