Class Method Details

.align ⇒ Integer

Returns the alignment of LibBin::Structure::Double_BE.

Returns:

• (Integer) —

  the byte boundary to align the type to.

# File 'lib/libbin/data_types.rb', line 3

.convert(input, output, input_big = LibBin::default_big?, output_big = !input_big, parent = nil, index = nil, length = nil) ⇒ Numeric⁺

Convert a field of class LibBin::Structure::Double_BE by loading it from input and dumping it to output. Returns the loaded field.

Parameters:

• input (IO) —

  the stream to load the field from.

• output (IO) —

  the stream to dump the field to.

• input_big (Boolean) (defaults to: LibBin::default_big?) —

  the endianness of input

• output_big (Boolean) (defaults to: !input_big) —

  the endianness of output.

• parent (Structure) (defaults to: nil) —

  ignored.

• index (Integer) (defaults to: nil) —

  ignored.

• length (Integer) (defaults to: nil) —

  if given the length of the vector. Else the length is considered to be 1.

Returns:

• (Numeric, Array<Numeric>) —

  the Ruby representation of the type, or the Array representation of the vector if length was specified

# File 'lib/libbin/data_types.rb', line 3

.dump(value, output, output_big = LibBin::default_big?, parent = nil, index = nil, length = nil) ⇒ nil

Dump a field of class LibBin::Structure::Double_BE to output.

Parameters:

• value (Numeric, Array<Numeric>) —

  the Ruby representation of the type, or the Array representation of the vector if length is specified.

• output (IO) —

  the stream to dump the field to.

• output_big (Boolean) (defaults to: LibBin::default_big?) —

  the endianness of output.

• parent (Structure) (defaults to: nil) —

  ignored.

• index (Integer) (defaults to: nil) —

  ignored.

• length (Integer) (defaults to: nil) —

  if given the length of the vector. Else the length is considered to be 1.

Returns:

• (nil)

# File 'lib/libbin/data_types.rb', line 3

.load(input, input_big = LibBin::default_big?, parent = nil, index = nil, length = nil) ⇒ Numeric⁺

Load a field of type LibBin::Structure::Double_BE from input, and return it.

Parameters:

• input (IO) —

  the stream to load the field from.

• input_big (Boolean) (defaults to: LibBin::default_big?) —

  the endianness of input

• parent (Structure) (defaults to: nil) —

  ignored.

• index (Integer) (defaults to: nil) —

  ignored.

• length (Integer) (defaults to: nil) —

  if given the length of the vector. Else the length is considered to be 1.

Returns:

• (Numeric, Array<Numeric>) —

  the Ruby representation of the type, or the Array representation of the vector if length was specified

# File 'lib/libbin/data_types.rb', line 3

.shape(value = nil, offset = 0, parent = nil, index = nil, kind = DataShape, length = nil) ⇒ kind

Returns the shape of a field of type LibBin::Structure::Double_BE

Parameters:

• value (Object) (defaults to: nil) —

  ignored.

• offset (Integer) (defaults to: 0) —

  start of the shape.

• parent (Structure) (defaults to: nil) —

  ignored.

• index (Integer) (defaults to: nil) —

  ignored.

• kind (Class) (defaults to: DataShape) —

  shape class. Will be instantiated through new with the offset and offset + sizeof(double) * length - 1.

• length (Integer) (defaults to: nil) —

  if given the length of the vector. Else the length is considered to be 1.

Returns:

• (kind) —

  a new instance of kind
