#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 locator binds to for peer-to-peer communication. If omitted or nil, the configuration will not be changed. If set to an empty string the locator will use the value derived from peer-discovery-address.

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

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

  • The ('client-port'Integer) —

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

  • The ('initial-heap'String) —

    intial heap size to be used by the locator’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 locator’s JVM when it is started. If omitted or nil, the configuration will not be changed

  • The ('max-heap'String) —

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

  • The ('peer-discovery-address'String) —

    property in a node’s metadata to use to determine the address that the locator binds to for peer-discovery communication. If omitted or nil, the configuration will not be changed. If set to an empty string the locator will use 0.0.0.0

  • The ('peer-discovery-port'Integer) —

    port that the locator listens on for peer-discovery connections. If omitted or nil, the configuration will not be changed

  • Whether ('run-netserver'Boolean) —

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