BinaryReaderCore extension

Core properties, operators, and lifecycle methods for BinaryReader.

Provides access to the reader's state (offset,length,availableBytes), random-access operator ([]), byte reading (call), and buffer rebinding (rebind).

Example:

final reader = BinaryReader(Uint8List.fromList([0x00, 0x01, 0x02, 0x03]));
print(reader.offset);    // 0
print(reader[0]);        // 0x00

reader.readUint32();
print(reader.offset);    // 4
print(reader.availableBytes);  // 0

// Rebind to new buffer
reader.rebind(Uint8List.fromList([0xFF]));
print(reader.offset);    // 0
on

Properties

availableBytes → int

Available on BinaryReader, provided by the BinaryReaderCore extension

Returns the number of bytes remaining to be read.
no setter
length → int

Available on BinaryReader, provided by the BinaryReaderCore extension

Returns the total length of the buffer in bytes.
no setter
offset → int

Available on BinaryReader, provided by the BinaryReaderCore extension

Returns the current read position in the buffer.
no setter

Methods

call(int length) → Uint8List

Available on BinaryReader, provided by the BinaryReaderCore extension

Reads length bytes from the current position.
rebind(Uint8List buffer) → void

Available on BinaryReader, provided by the BinaryReaderCore extension

Rebinds the reader to a new buffer without creating a new BinaryReader.

Operators

operator [](int index) → int

Available on BinaryReader, provided by the BinaryReaderCore extension

Returns the byte at the specified absolute index in the buffer.
