Inheritance diagram for DataInit< T, U >:
Detailed Description
template<class T, class U = typename TypeId::Get<T>::Id>
struct evo::DataInit< T, U >
Optimized data initialization and uninitialization helpers.
- Operations are specialized and optimized for POD and ByteCopy types where possible
- This is used by Evo containers
- Template Parameters
-
T Data type to use U Inferred from T

Member Function Documentation
◆ copy()
Copy already initialized data (assignment operator).
- Parameters
-
dest Destination data pointer - must be valid src Source data pointer - must be valid size Copy size - must be positive
◆ init() [1/3]
|
inlinestatic |
Initialize data using default constructor.
- Same as init_safe() except will not initialize new POD values, so is faster for POD types
- Parameters
-
data Data pointer - must be valid size Data size - must be positive
◆ init() [2/3]
Initialize data using copy constructor.
- Parameters
-
data Data pointer - must be valid src Source data to copy - must be valid count Number of items to copy - must be positive
◆ init() [3/3]
Initialize data using copy constructor and default constructor.
- Parameters
-
data Data pointer - must be valid size Data size - must be positive src Source data to copy - must be valid count Number of items to copy - must be positive
◆ init_safe() [1/2]
|
inlinestatic |
Initialize data using default constructor.
- Same as init(T*,ulong) except will initialize new POD values to 0, so is safer but slower for POD types
- Parameters
-
data Data pointer - must be valid size Data size - must be positive
◆ init_safe() [2/2]
Initialize data using copy constructor and default constructor.
- Same as init(Item*,ulong,const Item*,ulong) except will initialize new POD values to 0, so is safer but slower for POD types
- Parameters
-
data Data pointer - must be valid size Data size - must be positive src Source data to copy - must be valid count Number of items to copy - must be positive
◆ init_tail_fast()
|
inlinestatic |
Initialize new tail data (default constructor).
- This is usefull for growing an array and initializes new data when newSize is greater than oldSize
- Same as init_tail_safe() except will not initialize new POD values, so is faster for POD types
- Parameters
-
data Data pointer - must be valid oldSize Old data size that is already initialized newSize New data size that will need data initialized if larger
◆ init_tail_safe()
|
inlinestatic |
Initialize new tail data (default constructor).
- This is usefull for growing an array and initializes new data when newSize is greater than oldSize
- Same as init_tail_fast() except will initialize new POD values to 0, so is safer but slower for POD types
- Parameters
-
data Data pointer - must be valid oldSize Old data size that is already initialized newSize New data size that will need data initialized if larger
◆ initcopy()
Initialize new item as copy of src (copy constructor).
- Parameters
-
item Item to initialize src Source to copy
◆ uninit()
|
inlinestatic |
Uninitialize data (destructor).
- Parameters
-
data Data pointer - must be valid size Size of data
◆ uninit_free_ptr()
|
inlinestatic |
Uninitialize and free array of pointers (destructor).
- Skips null pointers
- Parameters
-
data Data pointer - must be valid size Size of data
◆ uninit_tail()
|
inlinestatic |
Uninitialize old tail data (destructor).
- This is usefull for shrinking an array and uninitializing old data when newSize is less than oldSize
- Parameters
-
data Data pointer - must be valid oldSize Old data size that is already initialized newSize New data size that will need data uninitialized if smaller
