IsolateByteStreamGenerator class abstract

An IsolateStreamGenerator for building an IsolateStream of bytes, represented by Uint8List instances. This could be used e.g. to simulate a large amount of data coming from a File or a Socket. As a convenience, this class implements sizeOf to count bytes, and bufferSize to give a reasonably large buffer.

Inheritance

Properties

bufferSize → int
Give a resonable default buffer size of 64K bytes.
no setteroverride
hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

add(Uint8List value) → void
Synchronously send the given value to the consumer, without regard to respecting the maximum buffer size. If this is called, the caller must ensure that flushIfNeeded is called frequently enough to prevent excessive buffer growth.
inherited
close() → void
Closes the sink.
inherited
flushIfNeeded() → Future<void>
If necessary, pause the sending isolate (the producer) until our consumer has processed sufficient data. await x.flushIfNeeded() should be called regularly, in order to ensure the Send/Receive port buffer between the isolates doesn't get too big.
inherited
generate() → Future<void>
Generate the values for the IsolateStream. An implementation of this method can send values using the appropriate methods of this class. When this method returns, the generating isolate is killed, and the IsolateStream is set as having received its last element.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
sendValue(Uint8List value) → Future<void>
Send the given value to the consumer, pausing if the buffer is full. This may only be called in the producer isolate.
inherited
sizeOf(Uint8List value) → int
Give number of bytes this element represents.
override
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
