Detailed Description

A writer of the Flutter standard binary encoding.

See FlutterStandardMessageCodec for details on the encoding.

The encoding is extensible via subclasses overriding writeValue.

Method Documentation

initWithData:

- (instancetype) initWithData:

(NSMutableData*)

data

Initial value:

{
  NSMutableData* _data

Create a FlutterStandardWriter who will write to data.

Definition at line 206 of file FlutterStandardCodec.mm.

                            :(NSMutableData*)data {
  self = [super init];
  NSAssert(self, @"Super init cannot be nil");
  _data = data;
  return self;
}

writeAlignment:

- (void) writeAlignment:

(UInt8)

alignment

Write zero padding until data is aligned with alignment.

Definition at line 229 of file FlutterStandardCodec.mm.

                      :(UInt8)alignment {
  FlutterStandardCodecHelperWriteAlignment((__bridge CFMutableDataRef)_data, alignment);
}

writeByte:

- (void) writeByte:

(UInt8)

value

Write a 8-bit byte.

Definition at line 213 of file FlutterStandardCodec.mm.

                 :(UInt8)value {
  FlutterStandardCodecHelperWriteByte((__bridge CFMutableDataRef)_data, value);
}

writeBytes:length:

- (void) writeBytes:		(const void*)	bytes
length:		(NSUInteger)	length

Write an array of bytes of size length.

Definition at line 217 of file FlutterStandardCodec.mm.

                  :(const void*)bytes length:(NSUInteger)length {
  FlutterStandardCodecHelperWriteBytes((__bridge CFMutableDataRef)_data, bytes, length);
}

writeData:

- (void) writeData:

(NSData*)

data

Write an array of bytes contained in data.

Definition at line 221 of file FlutterStandardCodec.mm.

                 :(NSData*)data {
  FlutterStandardCodecHelperWriteData((__bridge CFMutableDataRef)_data, (__bridge CFDataRef)data);
}

writeSize:

- (void) writeSize:

(UInt32)

size

Write 32-bit unsigned integer that represents a size of a collection.

Definition at line 225 of file FlutterStandardCodec.mm.

                 :(UInt32)size {
  FlutterStandardCodecHelperWriteSize((__bridge CFMutableDataRef)_data, size);
}

writeUTF8:

- (void) writeUTF8:

(NSString*)

value

Write a string with UTF-8 encoding.

Definition at line 233 of file FlutterStandardCodec.mm.

                 :(NSString*)value {
  FlutterStandardCodecHelperWriteUTF8((__bridge CFMutableDataRef)_data,
                                      (__bridge CFStringRef)value);
}

writeValue:

- (void) writeValue:

(id)

value

Introspects into an object and writes its representation.

Supported Data Types:

• NSNull
• NSNumber
• NSString (as UTF-8)
• FlutterStandardTypedData
• NSArray of supported types
• NSDictionary of supporte types

NSAsserts on failure.

Reimplemented in ExtendedWriter.

Definition at line 347 of file FlutterStandardCodec.mm.

                  :(id)value {
  FlutterStandardCodecObjcType type = GetWriteType(value);
  WriteValueOfType((__bridge CFTypeRef)self, (__bridge CFMutableDataRef)self->_data, type,
                   (__bridge CFTypeRef)value);
}
