Detailed Description

Service for listing all Components by iterator.

Member Data Documentation

create

mysql_service_status_t(* s_mysql_dynamic_loader_query::create) (my_h_component_iterator *out_iterator)

Creates iterator that iterates through all loaded components.

If successful it leaves read lock on dynamic loader until iterator is released.

Parameters

[out]

out_iterator

Pointer to component iterator handle.

Returns

Status of performed operation

Return values

false	success
true	failure

get

mysql_service_status_t(* s_mysql_dynamic_loader_query::get) (my_h_component_iterator iter, const char **out_name, const char **out_urn)

Gets name and URN of Service pointed to by iterator.

Parameters

	iterator	Component iterator handle.
[out]	out_name	Pointer to string with component name to set result pointer to.
[out]	out_urn	Pointer to string with URN from which the component was loaded from, to set result pointer to.

Returns

Status of performed operation

Return values

false	success
true	Failure, may be caused when called on iterator that went through all values already.

is_valid

mysql_service_status_t(* s_mysql_dynamic_loader_query::is_valid) (my_h_component_iterator iter)

Checks if specified iterator is valid, i.e.

have not reached one-past-last element.

Parameters

iterator

Component iterator handle.

Returns

Validity of iterator

Return values

false	Valid
true	Invalid or reached one-past-last element.

next

mysql_service_status_t(* s_mysql_dynamic_loader_query::next) (my_h_component_iterator iter)

Advances specified iterator to next element.

Will succeed but return true if it reaches one-past-last element.

Parameters

iterator

Component iterator handle.

Returns

Status of performed operation and validity of iterator after operation.

Return values

false	success
true	Failure or called on iterator that was on last element.

release

void(* s_mysql_dynamic_loader_query::release) (my_h_component_iterator iter)

Releases component iterator.

Releases read lock on dynamic loader.

Parameters

iterator

Component iterator handle.

Returns

Status of performed operation

Return values

false	success
true	failure
