default |
Constructor. (Allow for at least one non-virtual function in this class, as otherwise sometimes no virtual table is emitted.)
|
overridevirtual |
Return true
if the string matches its constraints, i.e. always.
Implements Patterns::PatternBase.
Definition at line 1466 of file patterns.cc.
|
overridevirtual |
Return a description of the pattern that valid strings are expected to match. Here, this is the string "[Anything]"
.
Implements Patterns::PatternBase.
Definition at line 1474 of file patterns.cc.
|
overridevirtual |
Return a copy of the present object, which is newly allocated on the heap. Ownership of that object is transferred to the caller of this function.
Implements Patterns::PatternBase.
Definition at line 1502 of file patterns.cc.

static |
Create a new object if the start of description matches description_init. Ownership of that object is transferred to the caller of this function.

Determine an estimate for the memory consumption (in bytes) of this object. To avoid unnecessary overhead, we do not force derived classes to provide this function as a virtual overloaded one, but rather try to cast the present object to one of the known derived classes and if that fails then take the size of this base class instead and add 32 byte (this value is arbitrary, it should account for virtual function tables, and some possible data elements). Since there are usually not many thousands of objects of this type around, and since the memory_consumption mechanism is used to find out where memory in the range of many megabytes is, this seems like a reasonable approximation.
On the other hand, if you know that your class deviates from this assumption significantly, you can still overload this function.
Reimplemented in Patterns::List, Patterns::Map, Patterns::MultipleSelection, Patterns::Selection, and Patterns::Tuple.
