BloombergLP::bsltf::StdAllocatorAdaptor

Synopsis

Declared in <bsltf_stdallocatoradaptor.h>

template<class ALLOCATOR>
class StdAllocatorAdaptor
    : public ALLOCATOR

Base Classes

Name	Description
`ALLOCATOR`

Types

Name	Description
`rebind`	This nested `struct` template, parameterized by some `BDE_OTHER_TYPE`, provides a namespace for an `other` type alias, which is an allocator type following the same template as this one but that allocates elements of `BDE_OTHER_TYPE`. Note that this allocator type is convertible to and from `other` for any `BDE_OTHER_TYPE` including `void`.

Type Aliases

Name	Description
`const_pointer`	Alias for `ALLOCATOR::const_pointer`.
`const_reference`	Alias for `ALLOCATOR::const_reference`.
`difference_type`	Alias for `ALLOCATOR::difference_type`.
`pointer`	Alias for `ALLOCATOR::pointer`.
`reference`	Alias for `ALLOCATOR::reference`.
`size_type`	Alias for `ALLOCATOR::size_type`.
`value_type`	Alias for `ALLOCATOR::value_type`.

Member Functions

Name	Description
`StdAllocatorAdaptor` [constructor]	Create a standard allocator adaptor object for a default-constructed allocator object of the (template parameter) type `ALLOCATOR`.
`StdAllocatorAdaptor` [constructor]	Create a copy of the specified `original` allocator adaptor.
`StdAllocatorAdaptor` [constructor]	Create a copy of the specified `other` allocator adaptor.
`StdAllocatorAdaptor` [constructor]	Create a standard allocator adaptor object from the null pointer constant.
`StdAllocatorAdaptor` [constructor]	Create a standard allocator adaptor object for the specified `allocator` of the (template parameter) type `ALLOCATOR`.
`operator=`	Assign to this object the value of the specified `rhs` object, and return a reference providing modifiable access to this object.
`allocator`	Return a reference to the non-modifiable allocator instance associated with this standard allocator adaptor.
`construct`	Construct an object of the (template parameter) `ELEMENT_TYPE`, by forwarding the allocator instance associated with this allocator adaptor, if appropriate, and the specified (variable number of) `arguments` to the corresponding constructor of `ELEMENT_TYPE`, at the specified uninitialized memory `address`. The behavior is undefined unless `address` is properly aligned for objects of `ELEMENT_TYPE`.
`select_on_container_copy_construction`	Return an allocator adaptor for the allocator object returned by the `select_on_container_copy_construction` class method in the `allocator_traits` class template for the allocator object, of the (template parameter) type `ALLOCATOR`, associated with this adaptor. The `allocator_traits` class template presumably delegates this call to the allocator object if such an operation is supported by the `ALLOCATOR` type, or provides a suitable default behavior if such an operation is not supported.
`operator BloombergLP::bslmf::NestedTraitDeclaration<StdAllocatorAdaptor, IsStdAllocator>`	Declare `StdAllocatorAdaptor` as a standard allocator.

Non-Member Functions

Name	Description
`operator!=`	Return `true` if the specified `lhs` and `rhs` adaptors are not equal and `false` otherwise. Two allocator adaptor instances are not equal if their associated allocator instances are not equal.
`operator==`	Return `true` if the specified `lhs` and `rhs` adaptors are equal and `false` otherwise. Two allocator adaptor instances are equal if their associated allocator instances are equal.
