TakeIfExists<(Of <(<'T>)>)> Method (template, tx)
Class Library ► GigaSpaces.Core ► ISpaceProxy ► TakeIfExists<(Of <<'(T>)>>)(T, ITransaction)
Take any matching object from the space, returning null if there currently is none. Equivalent to take, except that blocking is done only if necessary to wait for transactional state to settle.
