Examples with Connection org.apache.geode.cache.client.internal.Connection used on opensource projects

Example 1 with Connection

use of org.apache.geode.cache.client.internal.Connection in project geode by apache.

the class PooledConnection method emergencyClose.

public void emergencyClose() {
    Connection con = this.connection;
    if (con != null) {
        this.connection.emergencyClose();
    }
    this.connection = null;
}

Example 2 with Connection

use of org.apache.geode.cache.client.internal.Connection in project geode by apache.

the class CacheServerMaxConnectionsJUnitTest method testMaxCnxLimit.

/**
   * This test performs the following:<br>
   * 1)create server<br>
   * 2)initialize proxy object and create region for client<br>
   * 3)perform a PUT on client by acquiring Connection through proxy<br>
   * 4)stop server monitor threads in client to ensure that server treats this as dead client <br>
   * 5)wait for some time to allow server to clean up the dead client artifacts<br>
   * 6)again perform a PUT on client through same Connection and verify after the put that the
   * Connection object used was new one.
