[#BloombergLP-bslma-operator_not_eq-0e] = xref:BloombergLP.adoc[BloombergLP]::xref:BloombergLP/bslma.adoc[bslma]::operator!= :relfileprefix: ../../ :mrdocs: Return `true` unless the specified `lhs` and `rhs` are proxies for the same `bslma::TestAllocator` object, in which case return `false`. This is a practical implementation of the STL requirement that two allocators compare equal if and only if memory allocated from one can be deallocated from the other. Note that the two allocators need not be instantiated on the same type in order to compare equal. == Synopsis Declared in `<bslma_stdtestallocator.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- template< class T1, class T2> bool operator!=( xref:BloombergLP/bslma/StdTestAllocator.adoc[StdTestAllocator<T1>] const& lhs, xref:BloombergLP/bslma/StdTestAllocator.adoc[StdTestAllocator<T2>] const& rhs); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
