panda3d.core.MemoryUsagePointers

class MemoryUsagePointers

This is a list of pointers returned by a MemoryUsage object in response to some query.

Warning: once pointers are stored in a MemoryUsagePointers object, they are reference-counted, and will not be freed until the MemoryUsagePointers object is freed (or clear() is called on the object). However, they may not even be freed then; pointers may leak once they have been added to this structure. This is because we don’t store enough information in this structure to correctly free the pointers that have been added. Since this is intended primarily as a debugging tool, this is not a major issue.

This class is just a user interface to talk about pointers stored in a MemoryUsage object. It doesn’t even exist when compiled with NDEBUG.

__init__() → None
__init__(param0: MemoryUsagePointers) → None
getNumPointers() → size_t

Returns the number of pointers in the set.

Return type

size_t

getPointer(n: size_t) → ReferenceCount

Returns the nth pointer of the set.

Return type

ReferenceCount

getTypedPointer(n: size_t) → TypedObject

Returns the nth pointer of the set, typecast to a TypedObject if possible. If the pointer is not a TypedObject or if the cast cannot be made, returns nullptr.

Return type

TypedObject

getType(n: size_t) → TypeHandle

Returns the actual type of the nth pointer, if it is known.

Return type

TypeHandle

getTypeName(n: size_t) → str

Returns the type name of the nth pointer, if it is known.

getAge(n: size_t) → float

Returns the age of the nth pointer: the number of seconds elapsed between the time it was allocated and the time it was added to this set via a call to MemoryUsage.getPointers().

getPythonPointer(n: size_t) → object
clear() → None

Empties the set of pointers.

output(out: ostream) → None
getPointers() → list
getTypedPointers() → list
