The 'Resource allocators' table can be filled with the descriptors of
functions
that can produce a resource. These can be represented by:
1. constructors, or
2. ordinary functions that are able to:
a) return an allocated resource, or
b) make an object, this allocating function is called on, an allocated
resource, or
c) turn one of its actual parameters into an allocated resource.
For any allocating function, the fields in the columns labeled 'Returns a
resource object',
'"this" object is a resource' and 'Parameter number for the resource
object (1-based)'
should be used to depict situation (a, b or c) that takes place. The value
of the latter
column is expected to be an ordinal number (1-based) of the affected
parameter.
For example, this should be set to "2" if the function turns its second
parameter into
an allocated resource.
NOTE ABOUT CONSTRUCTORS
Any allocator with the name (the value of the appropriate field in the
'Function name' column)
that is exactly the same as the unqualified name of its declaring type
(the last segment of
the value of the field in 'Fully qualified type name or namespace' column)
is considered
a constructor. '"this" object is a resource' check box must be ticked for
constructors
that represent allocators. Changing values in fields '+ definitions in
subclasses',
'Returns a resource object' and 'Parameter number for the resource object
(1-based)' has no effect
on the analysis.
SETTING UP RESOURCE CLOSERS
The second pane can be filled with functions that close a resource by
being
called on the object that represents an allocated resource, or by being
passed a resource
