#update(options = {}) ⇒ void

This method returns an undefined value.

Updates the instance using the supplied options.

Options Hash (options):

  • The ('bind-address'String) —

    property in a node’s metadata to use to determine the address that the server binds to for peer-to-peer communication. If omitted or nil, the configuration will not be changed. If set to an empty string the server will use the node’s hostname

  • The ('client-bind-address'String) —

    property in a node’s metadata to use to determine the address that the server binds to for client communication. If omitted or nil, the configuration will not be changed. If set to an empty string the server will bind to localhost

  • The ('client-port'Integer) —

    port that the server listens on for client connections. If omitted or nil, the configuration will not be changed

  • Critical ('critical-heap-percentage'Integer) —

    heap threshold as a percentage of the old generation heap. Valid value are 0-100 inclusive. If omitted or nil, the configuration will not be changed

  • The ('initial-heap'String) —

    intial heap size to be used by the server’s JVM. If omitted or nil, the configuration will not be changed. If set to an empty string the JVM’s default is used

  • :installation (String) —

    The installation to be used by the instance. If omitted or nil, the configuration will not be changed.

  • The ('jvm-options'String[]) —

    JVM options that are passed to the server’s JVM when it is started. If omitted or nil, the configuration will not be chanaged

  • The ('max-heap'String) —

    maximum heap size to be used by the server’s JVM. If omitted or nil, the configuration will not be changed. If set to an empty string the JVM’s default is used

  • Whether ('run-netserver'Boolean) —

    the server should run a netserver that can service thin clients. If omitted or nil, the configuration will not be changed
