Constructor Detail

IpcReadOptions

public IpcReadOptions()

Default native constructor.

IpcReadOptions

public IpcReadOptions(long size)

Native array allocator. Access with Pointer.position(long).

IpcReadOptions

public IpcReadOptions(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

position

public IpcReadOptions position(long position)

Overrides:

position in class Pointer

getPointer

public IpcReadOptions getPointer(long i)

Overrides:

getPointer in class Pointer

max_recursion_depth

public int max_recursion_depth()

\brief The maximum permitted schema nesting depth.

max_recursion_depth

public IpcReadOptions max_recursion_depth(int setter)

memory_pool

public MemoryPool memory_pool()

\brief The memory pool to use for allocations made during IPC reading While Arrow IPC is predominantly zero-copy, it may have to allocate memory in some cases (for example if compression is enabled).

memory_pool

public IpcReadOptions memory_pool(MemoryPool setter)

included_fields

@StdVector
