Member Function Documentation

assign()

void ReadView::ids_t::assign ( const value_type *  start, const value_type *  end  )

private

Copy and overwrite the current array contents.

Copy and overwrite this array contents.

Parameters

start	Source array
end	Pointer to end of array

back()

value_type ReadView::ids_t::back ( ) const

inlineprivate

Returns

the value of the last element in the array

capacity()

ulint ReadView::ids_t::capacity ( ) const

inlineprivate

Returns

the capacity of the array in elements

clear()

void ReadView::ids_t::clear ( )

inlineprivate

Reset the size to 0.

data() [1/2]

trx_id_t * ReadView::ids_t::data ( )

inlineprivate

Returns

a pointer to the start of the array

data() [2/2]

const trx_id_t * ReadView::ids_t::data ( ) const

inlineprivate

Returns

a const pointer to the start of the array

empty()

bool ReadView::ids_t::empty ( ) const

inlineprivate

Returns

true if size() == 0

front()

value_type ReadView::ids_t::front ( ) const

inlineprivate

Returns

the value of the first element in the array

insert()

void ReadView::ids_t::insert ( value_type  value )

private

Insert the value in the correct slot, preserving the order.

Doesn't check for duplicates.

operator=()

ids_t & ReadView::ids_t::operator= ( const ids_t &  )

private

push_back()

void ReadView::ids_t::push_back ( value_type  value )

private

Append a value to the array.

Parameters

value

reserve()

void ReadView::ids_t::reserve ( ulint  n )

Parameters

n	Make space for n elements

Keep a minimum threshold

resize()

void ReadView::ids_t::resize ( ulint  n )

inlineprivate

Resize the array, sets the current element count.

Parameters

n	new size of the array, in elements

size()

ulint ReadView::ids_t::size ( ) const

inlineprivate

Returns

the number of elements in the array
