Constructor & Destructor Documentation

sync_allowed_latches() [1/2]

sync_allowed_latches::sync_allowed_latches ( const latch_level_t *  from, const latch_level_t *  to  )

inline

Constructor.

Parameters

[in]	from	first element in an array of latch_level_t
[in]	to	last element in an array of latch_level_t

sync_allowed_latches() [2/2]

sync_allowed_latches::sync_allowed_latches ( )

inline

Default constructor.

The list of allowed latches is empty.

Member Function Documentation

operator()()

virtual bool sync_allowed_latches::operator() ( const latch_level_t  level )

inlineoverridevirtual

Check whether the given latch_t violates the latch constraint.

This object maintains a list of allowed latch levels, and if the given latch belongs to a latch level that is not there in the allowed list, then it is a violation.

Parameters

[in]

level

The latch level to check

Returns

true if there is a latch ordering violation

Implements sync_check_functor_t.

result()

virtual bool sync_allowed_latches::result ( ) const

inlineoverridevirtual

Returns

the result of the check

Implements sync_check_functor_t.

Member Data Documentation

m_latches

latches_t sync_allowed_latches::m_latches

private

List of latch levels that are allowed to be held.

m_result

bool sync_allowed_latches::m_result

private

Save the result of validation check here True if all OK.
