DataOutputSink class

An adapter over a Sink<List<int>> for writing to a stream. This class presents an API based on Java's java.io.DataOutputStream.

DataOutputSink does no buffering.

Constructors

DataOutputSink(Sink<List<int>> _dest, [Endian endian = Endian.big])

Create a sink that sends its data to dest with the given initial endian setting. Choose Endian.big for interoperability with java.io.DataOutputStream.

Properties

endian ↔ Endian

The current endian setting, either Endian.big or Endian.little. This is used for converting numeric types. Choose Endian.big for interoperability with java.io.DataOutputStream.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

close() → void

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

writeBoolean(bool v) → void

Writes a byte containg 0 if v is false, and 1 if it is true.

writeByte(int b) → void

Write the low 8 bits of the given integer as a single byte.

writeBytes(List<int> bytes) → void

Write the given bytes. A Uint8List is the recommended subtype of List<int>.

writeDouble(double v) → void

Writes an eight-byte double using the current endian format.

writeFloat(double v) → void

Writes a four-byte float using the current endian format.

writeInt(int v) → void

Writes a 4 byte int using the current endian format.

writeLong(int v) → void

Writes an 8 byte long int using the current endian format.

writeShort(int v) → void

Writes a 2 byte signed short using the current endian format.

writeUnsignedInt(int v) → void

Writes a 4 byte unsigned int using the current endian format.

writeUnsignedLong(int v) → void

Writes an unsigned 8 byte long using the current endian format. Converts a Dart int according to the semantics of [ByteData.setUint64`.

writeUnsignedShort(int v) → void

Writes a 2 byte unsigned short using the current endian format.

writeUTF8(String s) → void

Write the given string as an unsigned short giving the byte length, followed by that many bytes containing the UTF8 encoding. The short is written using the current endian format. This should be compatible with Java's DataOutputStream.writeUTF8(), as long as the string contains no nulls and no UTF formats beyond the 1, 2 and 3 byte formats. See https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/io/DataInput.html#modified-utf-8

Operators

operator ==(Object other) → bool

The equality operator.
