Detailed Description

template<typename T>
class System::Buffers::MemoryManager< T >

Provides an abstraction for managing memory blocks.

Template Parameters

T	The type of elements in the memory.

Member Function Documentation

◆ CreateMemory() [1/2]

template<typename T >

Memory< T > System::Buffers::MemoryManager< T >::CreateMemory ( int length ) const

inlineprotected

Creates a Memory<T> instance representing this MemoryManager starting at offset 0.

Parameters

length The element count in the memory, starting at offset 0.

◆ CreateMemory() [2/2]

template<typename T >

Memory< T > System::Buffers::MemoryManager< T >::CreateMemory	(	int	start,
		int	length
	)

inlineprotected

Creates a Memory<T> instance representing a sub-range of this MemoryManager.

Parameters

start	The offset to the element at which the returned memory starts.
length	The element count in the memory, starting at element offset start.

◆ Dispose() [1/2]

template<typename T >

void System::Buffers::MemoryManager< T >::Dispose ( )

inlineoverridevirtual

Disposes the memory manager and releases any resources it holds.

Reimplemented from System::IDisposable.

◆ Dispose() [2/2]

template<typename T >

virtual void System::Buffers::MemoryManager< T >::Dispose ( bool disposing )

protectedpure virtual

Releases resources held by the manager.

Parameters

disposing True when called from Dispose(), false when called from destructor.

◆ get_Memory()

template<typename T >

virtual Memory< T > System::Buffers::MemoryManager< T >::get_Memory ( )

inlinevirtual

Returns a Memory<T>.

◆ GetSpan()

template<typename T >

virtual Span< T > System::Buffers::MemoryManager< T >::GetSpan ( )

pure virtual

Returns a span wrapping the underlying memory.

◆ Pin()

template<typename T >

virtual MemoryHandle System::Buffers::MemoryManager< T >::Pin ( int32_t elementIndex = 0 )

pure virtual

Returns a handle to the memory that has been pinned so its address can be taken.

Parameters

elementIndex The offset to the element within the memory at which the returned MemoryHandle points. Defaults to 0.

◆ Unpin()

template<typename T >

virtual void System::Buffers::MemoryManager< T >::Unpin ( )

pure virtual

Indicates the memory can be moved again; unpins previously pinned memory.
