Constructor Detail

BufferReader

public BufferReader(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

closed

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

\brief Instantiate from std::string or arrow::util::string_view. Does not own data

Overrides:

closed in class FileInterface

supports_zero_copy

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

Description copied from class: InputStream

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

Overrides:

supports_zero_copy in class InputStream

buffer

@SharedPtr
public ArrowBuffer buffer()
