Method Detail

forSensor

public static <T> CommandPollConfig<T> forSensor(AttributeSensor<T> sensor)

forMultiple

public static CommandPollConfig<java.lang.Void> forMultiple()

getCommand

@Deprecated
public java.lang.String getCommand()

Deprecated. since 0.7.0; use getCommandSupplier() and resolve just-in-time

getCommandSupplier

public com.google.common.base.Supplier<java.lang.String> getCommandSupplier()

getEnv

@Deprecated
public java.util.Map<java.lang.String,java.lang.String> getEnv()

Deprecated. since 0.7.0; use getEnvSupplier() and resolve just-in-time

command

public CommandPollConfig<T> command(java.lang.String val)

command

public CommandPollConfig<T> command(com.google.common.base.Supplier<java.lang.String> val)

env

public CommandPollConfig<T> env(java.lang.String key,
                                java.lang.String val)

add the given env param; sequence is as per env(Supplier)

env

public CommandPollConfig<T> env(java.util.Map<java.lang.String,java.lang.String> val)

add the given env params; sequence is as per env(Supplier). behaviour is undefined if the map supplied here is subsequently changed.

if a map's contents might change, use env(Supplier)

env

public CommandPollConfig<T> env(com.google.common.base.Supplier<java.util.Map<java.lang.String,java.lang.String>> val)

adds the given dynamic supplier of environment variables.

use of a supplier allows env vars to be computed on each execution, for example to take the most recent sensor values.

in the case of multiple map suppliers, static maps, or static env(String, String) key value pairs, the order in which they are specified here is the order in which they are computed and applied.
