class Context from ShapeProcess inherits TShared from MMgt
---Purpose: Provides convenient interface to resource file
-- Allows to load resource file and get values of
-- attributes starting from some scope, for example
-- if scope is defined as "ToV4" and requested parameter
-- is "exec.op", value of "ToV4.exec.op" parameter from
-- the resource file will be returned
uses
Manager from Resource,
AsciiString from TCollection,
HSequenceOfHAsciiString from TColStd,
Messenger from Message
is
Create;
---Purpose: Creates an empty tool
Create (file: CString; scope: CString = "");
---Purpose: Creates a new tool and initialises by name of
-- resource file and (if specified) starting scope
-- Calls method Init()
Init (me: mutable; file: CString; scope: CString = "")
returns Boolean;
---Purpose: Initialises a tool by loading resource file and
-- (if specified) sets starting scope
-- Returns False if resource file not found
LoadResourceManager(me: mutable; file: CString) returns Manager from Resource;
---Purpose: Loading Resource_Manager object if this object not
-- equal internal static Resource_Manager object or
-- internal static Resource_Manager object is null
ResourceManager (me) returns Manager from Resource;
---Purpose: Returns internal Resource_Manager object
---C++: return const &
SetScope (me: mutable; scope: CString);
---Purpose: Set a new (sub)scope
UnSetScope (me: mutable);
---Purpose: Go out of current scope
IsParamSet (me; param: CString) returns Boolean;
---Purpose: Returns True if parameter is defined in the resource file
GetReal (me; param: CString; val: out Real ) returns Boolean;
GetInteger (me; param: CString; val: out Integer) returns Boolean;
GetBoolean (me; param: CString; val: out Boolean) returns Boolean;
GetString (me; param: CString; val: out AsciiString from TCollection) returns Boolean;
---Purpose: Get value of parameter as being of specific type
-- Returns False if parameter is not defined or has a wrong type
RealVal (me; param: CString; def: Real ) returns Real;
IntegerVal (me; param: CString; def: Integer) returns Integer;
BooleanVal (me; param: CString; def: Boolean) returns Boolean;
StringVal (me; param: CString; def: CString) returns CString;
---Purpose: Get value of parameter as being of specific type
-- If parameter is not defined or does not have expected
-- type, returns default value as specified
SetMessenger (me: mutable; messenger: Messenger from Message);
---Purpose : Sets Messenger used for outputting messages.
Messenger (me) returns Messenger from Message;
---Purpose : Returns Messenger used for outputting messages.
SetTraceLevel (me: mutable; tracelev: Integer);
---Purpose : Sets trace level used for outputting messages
-- - 0: no trace at all
-- - 1: errors
-- - 2: errors and warnings
-- - 3: all messages
-- Default is 1 : Errors traced
TraceLevel (me) returns Integer;
---Purpose : Returns trace level used for outputting messages.
