Constructor Detail

KernelContext

public KernelContext(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

KernelContext

public KernelContext(ExecContext exec_ctx)

Method Detail

Allocate

@ByVal
public ResizableResult Allocate(@Cast(value="int64_t")
                                        long nbytes)

\brief Allocate buffer from the context's memory pool. The contents are not initialized.

SetState

public void SetState(KernelState state)

\brief Assign the active KernelState to be utilized for each stage of kernel execution. Ownership and memory lifetime of the KernelState must be minded separately.

state

public KernelState state()

exec_context

public ExecContext exec_context()

\brief Configuration related to function execution that is to be shared across multiple kernels.

memory_pool

public MemoryPool memory_pool()

\brief The memory pool to use for allocations. For now, it uses the MemoryPool contained in the ExecContext used to create the KernelContext.
