Buffer — bytes | Standard libraries

Class Buffer

A buffer that can be used to build byte data.

Deprecated. Use io.Buffer instead.

Aliases

BytesBuilder: Dart
ByteArrayOutputStream: Java

Class summary

constructor	Constructs a new buffer.

Constructors

constructor

Constructs a new buffer.

The backing byte array is allocated with a default size and will grow if needed.

Statics

with-initial-size init-size_/int -> Buffer

Constructs a new buffer with the given init-size_.

If the init-size_ isn't big enough, the buffer grows when necessary.

Methods

buffer -> ByteArray

The backing byte array.

The buffer might have a size bigger than size.

bytes -> ByteArray

Return a view of the buffer, limited to 0..size.

clear -> none

See BufferConsumer.clear.

close -> none

See BufferConsumer.close.

Trims the backing store to avoid waste.

grow amount/int -> none

See BufferConsumer.grow.

operator == other/any -> bool

Whether this object is equal to the other.

By default, identical is used for equality.

Inheritance

Classes overwrite this operator to get an equality specific to their needs. Equality operators often compare the type and field contents. For example:


class Pin:
  number/int

  constructor .number:

  operator == other:
    if other is not Pin: return false
    return number == other.number

A class doesn't have to follow the above format, but it must keep the operator in sync with any hash-code method. That is, if a class has a hash-code member, then the equality and hash-code must agree. If two instances are equal (a == b), then their hash codes must also be equal (a.hash-code == b.hash-code).
