Constructor Detail

InputStream

public InputStream(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

Method Detail

asReadable

public Readable asReadable()

asReadable

@Namespace
 @Name(value="static_cast<arrow::io::Readable*>")
public static Readable asReadable(InputStream pointer)

Advance

@ByVal
public Status Advance(@Cast(value="int64_t")
                             long nbytes)

\brief Advance or skip stream indicated number of bytes

Parameters:

nbytes - [in] the number to move forward

Returns:

Status

Peek

@ByVal
public StringViewResult Peek(@Cast(value="int64_t")
                                    long nbytes)

\brief Return zero-copy string_view to upcoming bytes. Do not modify the stream position. The view becomes invalid after any operation on the stream. May trigger buffering if the requested size is larger than the number of buffered bytes. May return NotImplemented on streams that don't support it.

Parameters:

nbytes - [in] the maximum number of bytes to see

supports_zero_copy

@Cast(value="bool")
public boolean supports_zero_copy()

\brief Return true if InputStream is capable of zero copy Buffer reads Zero copy reads imply the use of Buffer-returning Read() overloads.
