SGALocal

public SGALocal(csbase.server.plugin.service.IServiceManager serviceManager)

Construtor obrigatório.

Parameters:

serviceManager - gerente dos serviços

Method Detail

init

protected void init()

Método de inicialização onde são definidos os executor e monitor. Deve ser sobreescrito nas classes que extendem SGALocal para definirem implementações específicas de JobExecutor e EnvironmentMonitor usando os métodos setExecutor(JobExecutor) e setMonitor(EnvironmentMonitor) respectivamente. A implementação padrão usa DefaultJobExecutor e EnvironmentMonitor.

getExecutor

protected JobExecutor getExecutor()

Obtém o executor de jobs.

Returns:

o executor

setExecutor

protected void setExecutor(JobExecutor executor)

Define o executor de jobs.

Parameters:

executor - o executor

getMonitor

protected EnvironmentMonitor getMonitor()

Obtém o monitor do ambiente de execução.

Returns:

o monitor

setMonitor

protected void setMonitor(EnvironmentMonitor monitor)

Difine o monitor do ambiente de execução.

Parameters:

monitor - o monitor

executeCommand
