Class: WritableDataChannel

Represents a WritableDataChannel for writing data.

Constructor

Initializes data channel.

init (WritableByteChannel byteChannel, ByteOrder bOrder)

byteChannel WritableByteChannel
channel which would represent the source to read/write data

bOrder ByteOrder "BE"
network byte order

Methods

writeInt16	Writes a 16 bit integer.
writeInt32	Writes a 32 bit integer.
writeInt64	Writes a 64 bit integer.

writeFloat64	Writes a 64 bit float.
writeBool	Writes a boolean.
writeString	Writes a given string value to the respective channel.
writeVarInt	Writes a variable-length integer.
close	Closes the data channel.

writeInt16

function writeInt16(int value) returns Error?

Isolated Function

Writes a 16 bit integer.


1io:Error? err = dataChannel.writeInt16(length);

Parameters

value int

The integer, which will be written

Return Type

(Error?)

() if the content is written successfully or else an io:Error if any error occurred

writeInt32

function writeInt32(int value) returns Error?

Isolated Function

Writes a 32 bit integer.


1io:Error? err = dataChannel.writeInt32(length);

Parameters

value int

The integer, which will be written

Return Type

(Error?)

() if the content is written successfully or else an io:Error if any error occurred

writeInt64

function writeInt64(int value) returns Error?

Isolated Function

Writes a 64 bit integer.


1io:Error? err = dataChannel.writeInt64(length);

Parameters

value int

The integer, which will be written

Return Type

(Error?)

() if the content is written successfully or else an io:Error if any error occurred

writeFloat32

function writeFloat32(float value) returns Error?

Isolated Function

Writes a 32 bit float.


1io:Error? err = dataChannel.writeFloat32(3.12);

Parameters

value float

The float, which will be written

Return Type

(Error?)

() if the float is written successfully or else an io:Error if any error occurred

writeFloat64

function writeFloat64(float value) returns Error?

Isolated Function

Writes a 64 bit float.


1io:Error? err = dataChannel.writeFloat32(3.12);

Parameters

value float

The float, which will be written

Return Type

(Error?)

() if the float is written successfully or else an io:Error if any error occurred

writeBool

function writeBool(boolean value) returns Error?

Isolated Function

Writes a boolean.


1io:Error? err = dataChannel.writeInt64(length);

Parameters

value boolean

The boolean, which will be written

Return Type

(Error?)

() if the content is written successfully or else an io:Error if any error occurred

writeString

function writeString(string value, string encoding) returns Error?

Isolated Function

Writes a given string value to the respective channel.


1io:Error? err = dataChannel.writeString(record);

Parameters

value string

The value, which should be written

encoding string

The encoding, which will represent the value string

Return Type

(Error?)

() if the content is written successfully or else an io:Error if any error occurred

writeVarInt

function writeVarInt(int value) returns Error?

Isolated Function

Writes a variable-length integer.


1io:Error? err = dataChannel.writeVarInt(length);

Parameters

value int

The int, which will be written

Return Type

(Error?)

The value of the integer, which is written or else an io:Error if any error occurred

close

function close() returns Error?

Isolated Function

Closes the data channel. After a channel is closed, any further writing operations will cause an error.


1io:Error? err = dataChannel.close();

Return Type

(Error?)

() if the channel is closed successfully or else an io:Error if any error occurred
