Member Function Documentation

addMemory()

virtual void zyncarla::Allocator::addMemory ( void * , size_t mem_size )

pure virtual

Implemented in zyncarla::AllocatorClass, and zyncarla::DummyAllocator.

alloc()

template<typename T, typename... Ts>

T * zyncarla::Allocator::alloc ( Ts &&... ts )

inline

High level allocator method, which return a pointer to a class or struct allocated with the specialized subclass strategy

Parameters

ts	argument(s) for the constructor of the type T

Returns

a non null pointer to a new object of type T

Exceptions

std::bad_alloc

is no memory could be allocated

alloc_mem()

virtual void * zyncarla::Allocator::alloc_mem ( size_t mem_size )

pure virtual

Implemented in zyncarla::AllocatorClass, and zyncarla::DummyAllocator.

append_alloc_to_memory_transaction()

void zyncarla::Allocator::append_alloc_to_memory_transaction ( void * new_memory )

inlineprivate

Append memory block to the list of memory blocks allocated during this transaction

Parameters

new_memory

pointer to the memory pointer to freshly allocated

beginTransaction()

valloc()

template<typename T, typename... Ts>

T * zyncarla::Allocator::valloc ( size_t len, Ts &&... ts )

inline

High level allocator method, which return a pointer to an array of class or struct allocated with the specialized subclass strategy

Parameters

len	the array length
ts	argument(s) for the constructor of the type T

Returns

a non null pointer to an array of new object(s) of type T

Exceptions

std::bad_alloc

is no memory could be allocated
