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  )

Retrieves an iterator pointing to null.

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 evalutes to true if this object's underlying head point to a difference address of the parameter object.

Parameters
rhsThe 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 evalutes to true if both object's underlying head point to the different addresses.

Parameters
rhsThe 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 evalutes to true if this object's underlying head points to a non-null value.

Parameters
rhsThe 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
rhsThe 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
rhsThe 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 evalutes to true if this object's underlying head point to the same address of the parameter object.

Parameters
rhsThe 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== ( Ha_trx_info_list const &  rhs) const

Equality operator that compares with another instance of this class.

It evalutes to true if both object's underlying head point to the same address.

Parameters
rhsThe object to compare this object to.
