Class ClientSmartFile

java.lang.Object

csbase.client.ClientSmartFile

All Implemented Interfaces:

csbase.logic.ClientFile

public class ClientSmartFile
extends java.lang.Object
implements csbase.logic.ClientFile

Modela a visão do cliente para um arquivo ou diretório de um projeto no modo otimizado.

Operações de IO: Sempre tenta utilizar o mounting point definido em localProjectPath. Caso não consiga, tem o comportamento de ClientProjectFile
Operação de controle: Em geral, repassa a ação para o ClientProjectFile original.

Deve ser instanciada sempre pelo método create() de ClientSmartFileFactory

Constructor Detail

ClientSmartFile

public ClientSmartFile(csbase.logic.ClientProjectFile cpf,
               csbase.logic.ClientOptimizationMode optimizationMode,
               java.lang.String localProjectPath)

Construtor. Deve ser chamado sempre por ClientSmartFileFactory.
O arquivo a princípio mantém o modo de otimização passado no construtor, mas caso o arquivo local não seja encontrado ou não esteja acessível para leitura, a otimização neste arquivo fica desabilitada.

Parameters:

cpf - ClientProjectFile que será utilizado para acesso ao projeto

optimizationMode - Modo de otimização

localProjectPath - Caminho da área local de projetos

Method Detail

getClientProjectFile

public csbase.logic.ClientProjectFile getClientProjectFile()

Returns:

O ClientPtojectFile encapsulado

getClientLocalFile

public ClientLocalFile getClientLocalFile()

Returns:

O ClientLocalFile (Arquivo na pasta local de projetos)
