!= | (1) Signature: [const] bool != (const Metrics other) Description: Compares two enums for inequality |
(2) Signature: [const] bool != (int other) Description: Compares an enum with an integer for inequality | |
< | (1) Signature: [const] bool < (const Metrics other) Description: Returns true if the first enum is less (in the enum symbol order) than the second |

Euclidian | Signature: [static,const] Metrics Euclidian Description: Specifies Euclidian metrics for the check functions This value can be used for the metrics parameter in the check functions, i.e. width_check. This value specifies Euclidian metrics, i.e. the distance between two points is measured by: d = sqrt(dx^2 + dy^2) All points within a circle with radius d around one point are considered to have a smaller distance than d. Python specific notes: |
Projection | Signature: [static,const] Metrics Projection Description: Specifies projected distance metrics for the check functions This value can be used for the metrics parameter in the check functions, i.e. width_check. This value specifies projected metrics, i.e. the distance is defined as the minimum distance measured perpendicular to one edge. That implies that the distance is defined only where two edges have a non-vanishing projection onto each other. Python specific notes: |
Square | Signature: [static,const] Metrics Square Description: Specifies square metrics for the check functions This value can be used for the metrics parameter in the check functions, i.e. width_check. This value specifies square metrics, i.e. the distance between two points is measured by: d = max(abs(dx), abs(dy)) All points within a square with length 2*d around one point are considered to have a smaller distance than d in this metrics. Python specific notes: |
_const_cast | Signature: [const] Metrics ptr _const_cast Description: Returns a non-const reference to self. Basically, this method allows turning a const object reference to a non-const one. This method is provided as last resort to remove the constness from an object. Usually there is a good reason for a const object reference, so using this method may have undesired side effects. This method has been introduced in version 0.29.6. |
_create | Signature: void _create Description: Ensures the C++ object is created Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. |
_destroy | Signature: void _destroy Description: Explicitly destroys the object Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. |
_destroyed? | Signature: [const] bool _destroyed? Description: Returns a value indicating whether the object was already destroyed This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. |
_is_const_object? | Signature: [const] bool _is_const_object? Description: Returns a value indicating whether the reference is a const reference This method returns true, if self is a const reference. In that case, only const methods may be called on self. |
_manage | Signature: void _manage Description: Marks the object as managed by the script side. After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. |
_unmanage | Signature: void _unmanage Description: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. |
assign | Signature: void assign (const Metrics other) Description: Assigns another object to self |
create | Signature: void create Description: Ensures the C++ object is created Use of this method is deprecated. Use _create instead Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. |
destroy | Signature: void destroy Description: Explicitly destroys the object Use of this method is deprecated. Use _destroy instead Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. |
destroyed? | Signature: [const] bool destroyed? Description: Returns a value indicating whether the object was already destroyed Use of this method is deprecated. Use _destroyed? instead This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. |
dup | Signature: [const] new Metrics ptr dup Description: Creates a copy of self Python specific notes: |
hash | Signature: [const] int hash Description: Gets the hash value from the enum Python specific notes: |
inspect | Signature: [const] string inspect Description: Converts an enum to a visual string Python specific notes: |
is_const_object? | Signature: [const] bool is_const_object? Description: Returns a value indicating whether the reference is a const reference Use of this method is deprecated. Use _is_const_object? instead This method returns true, if self is a const reference. In that case, only const methods may be called on self. |
