Detailed Description

Iterator over transaction list.

This is exposed for the purpose of coping with out-of-log-space conditions. See SSMLOG.

Constructor & Destructor Documentation

xct_i() [1/2]

xct_i::xct_i ( bool  locked_accesses )

inline

Constructor.

Parameters

[in]

locked_accesses

Set to true if you want this iterator to be safe, false if you don't care or if you already hold the transaction-list mutex.

~xct_i()

xct_i::~xct_i ( )

inline

Desctructor. Calls never_mind() if necessary.

xct_i() [2/2]

xct_i::xct_i ( const xct_i &  )

private

Member Function Documentation

_check()

void xct_i::_check ( bool  b ) const

inlineprivate

curr()

xct_t* xct_i::curr ( ) const

inline

Get transaction at cursor.

locked_by_me()

bool xct_i::locked_by_me ( ) const

inline

True if this thread holds the transaction list mutex.

never_mind()

void xct_i::never_mind ( )

inline

Release transaction list mutex if this thread holds it.

next()
