NAME

Kafka::MockIO - object interface to simulate the socket communications with the Apache Kafka server.

VERSION

This documentation refers to Kafka::MockIO version 0.800_2 .

DESCRIPTION

This module is not a user module.

The main features of the Kafka::MockIO class are:

  • Emulates an object oriented model of communication (Kafka::IO class).

  • Simplistically emulates interaction with kafka server.

Examples see t/??_mock_io.t.

EXPORT

These variables are the constants and never change their values.

Use Kafka::MockIO only with the following information:

$PARTITION

Partition number.

$KAFKA_MOCK_SERVER_PORT

$KAFKA_MOCK_SERVER_PORT is the default Apache Kafka server port that can be imported from the Kafka module and = 9092.

FUNCTIONS

The following methods are defined for the Kafka::MockIO class:

override

Override the Kafka::IO class methods.

restore

Restore the Kafka::IO class methods.

add_special_case( $cases )

Adds special cases for use in the simulation of interaction with kafka server.

This function take argument. The following argument is currently recognized:

$cases

$cases is a reference to the hash representing the special cases.

The keys of the hash should be binary-encoded query string to kafka server. The values of each key must be encoded binary string of the expected response.

del_special_case( $encoded_request )

Removes the special case.

This function take argument. The following argument is currently recognized:

$encoded_request

Binary string of the encoded request.

special_cases

Returns a reference to a hash of special cases.

The keys of the hash are binary strings encoded requests to kafka server. The value of each key is encoded binary string of the expected response.

CONSTRUCTOR

new

Constructor emulation (Kafka::IO-new>).

METHODS

The following methods are defined for the Kafka::MockIO class:

send

Method emulation (Kafka::IO::send).

receive
