Member Function Documentation

begin() [1/2]

Ha_trx_info_list::Iterator Ha_trx_info_list::begin

(

void

)

Retrieves an iterator pointing to the underlying list head.

Returns

An iterator pointing to the underlying list head.

begin() [2/2]

const Ha_trx_info_list::Iterator Ha_trx_info_list::begin

(

void

)

const

Retrieves an iterator pointing to the underlying list head.

Returns

An iterator pointing to the underlying list head.

end() [1/2]

Ha_trx_info_list::Iterator Ha_trx_info_list::end

(

void

)

Returns

An iterator pointing null.

end() [2/2]

const Ha_trx_info_list::Iterator Ha_trx_info_list::end

(

void

)

const

Retrieves an iterator pointing to null.

Returns

An iterator pointing null.

head()

Ha_trx_info * Ha_trx_info_list::head

(

)

Retrieves the pointer to the underlying list head.

Returns

The underlying list head.

operator bool()

Ha_trx_info_list::operator bool

(

)

const

Cast operator to bool.

It returns true if the this object underlying list head doesn't point to null, false otherwise.

Returns

true if the this object underlying list head doesn't point to null, false otherwise.

operator!=() [1/3]

bool Ha_trx_info_list::operator!=

(

Ha_trx_info const *

rhs

)

const

Inequality operator that compares with an instance of Ha_trx_info class.

It evaluates to true if this object's underlying head points to a different address of the parameter object.

Parameters

rhs	The object to compare this object to.

Returns

true if this object's underlying head point to different address as the parameter object, false otherwise.

operator!=() [2/3]

bool Ha_trx_info_list::operator!=

(

Ha_trx_info_list const &

rhs

)

const

Inequality operator that compares with another instance of this class.

It evaluates to true if both object's underlying head point to the different addresses.

Parameters

rhs	The object to compare this object to.

Returns

true if both object's underlying head point to different addresses, false otherwise.

operator!=() [3/3]

bool Ha_trx_info_list::operator!=

(

std::nullptr_t

rhs

)

const

Inequality operator that compares with null.

It evaluates to true if this object's underlying head points to a non-null value.

Parameters

rhs	The nullptr value

Returns

true if this object's underlying head point to a non-null value, false otherwise.

operator*() [1/2]

Ha_trx_info & Ha_trx_info_list::operator*

(

)

Retrieves the reference to the undelying head of the list.

Returns

The reference to the undelying head of the list.

operator*() [2/2]

Ha_trx_info const & Ha_trx_info_list::operator*

(

)

const

Retrieves the reference to the undelying head of the list.

Returns

The reference to the undelying head of the list.

operator->() [1/2]

Ha_trx_info * Ha_trx_info_list::operator->

(

)

Retrieves the pointer to the undelying head of the list.

Returns

The pointer to the undelying head of the list.

operator->() [2/2]

Ha_trx_info const * Ha_trx_info_list::operator->

(

)

const

Retrieves the pointer to the undelying head of the list.

Returns

The pointer to the undelying head of the list.

operator=() [1/2]

Ha_trx_info_list & Ha_trx_info_list::operator=

(

Ha_trx_info_list &&

rhs

)

Move operator.

Parameters

rhs	The object instance to move content from.

Returns

this object reference, for chaining puposes.

operator=() [2/2]

Ha_trx_info_list & Ha_trx_info_list::operator=

(

Ha_trx_info_list const &

rhs

)

Copy operator.

Parameters

rhs	The object instance to copy content from.

Returns

this object reference, for chaining puposes.

operator==() [1/3]

bool Ha_trx_info_list::operator==

(

Ha_trx_info const *

rhs

)

const

Equality operator that compares with an instance of Ha_trx_info class.

It evaluates to true if this object's underlying head points to the same address of the parameter object.

Parameters

rhs	The object to compare this object to.

Returns

true if this object's underlying head point to the same address as the parameter object, false otherwise.

operator==() [2/3]

bool Ha_trx_info_list::operator==
