Types

type GlogLogger 

type GlogLogger struct {
	// contains filtered or unexported fields
}

GlogLogger is a logger that uses the glog V mechanism.

func (*GlogLogger) Error 

func (l *GlogLogger) Error(ctx context.Context, format string, args ...interface{})

Error sends to the log an error message formatted using the fmt.Sprintf function and the given format and arguments.

func (*GlogLogger) ErrorEnabled 

func (l *GlogLogger) ErrorEnabled() bool

ErrorEnabled returns true iff the error level is enabled.

func (*GlogLogger) Fatal 

func (l *GlogLogger) Fatal(ctx context.Context, format string, args ...interface{})

Fatal sends to the log an error message formatted using the fmt.Sprintf function and the given format and arguments. After that it will os.Exit(1) This level is always enabled

func (*GlogLogger) Info 

func (l *GlogLogger) Info(ctx context.Context, format string, args ...interface{})

Info sends to the log an information message formatted using the fmt.Sprintf function and the given format and arguments.

type GlogLoggerBuilder 

type GlogLoggerBuilder struct {
	// contains filtered or unexported fields
}

GlogLoggerBuilder contains the configuration and logic needed to build a logger that uses the glog V mechanism. Don't create instances of this type directly, use the NewGlogLoggerBuilder function instead.

func NewGlogLoggerBuilder 

func NewGlogLoggerBuilder() *GlogLoggerBuilder

NewGlogLoggerBuilder creates a builder that uses the glog V mechanism. By default errors, warnings and information messages will be written to the log if the level is 0 or greater, and debug messages will be written if the level is 1 or greater. This can be changed using the ErrorV, WarnV, InfoV and DebugV methods of the builder. For example, to write errors and warnings for level 0, information messages for level 1, and debug messages for level 2, you can create the logger like this: 

logger, err := client.NewGlobLoggerBuilder().
	ErrorV(0).
	WarnV(0).
	InfoV(1).
	DebugV(2).
	Build()

Once the logger is created these settings can't be changed.

func (*GlogLoggerBuilder) Build 

func (b *GlogLoggerBuilder) Build() (logger *GlogLogger, err error)

Build creates a new logger using the configuration stored in the builder.

func (*GlogLoggerBuilder) DebugV

DebugV sets the V value that will be used for debug messages.

func (*GlogLoggerBuilder) ErrorV 

func (b *GlogLoggerBuilder) ErrorV(v glog.Level) *GlogLoggerBuilder

ErrorV sets the V value that will be used for error messages.

func (*GlogLoggerBuilder) InfoV 

func (b *GlogLoggerBuilder) InfoV(v glog.Level) *GlogLoggerBuilder

InfoV sets the V value that will be used for info messages.

func (*GlogLoggerBuilder) WarnV 

func (b *GlogLoggerBuilder) WarnV(v glog.Level) *GlogLoggerBuilder

WarnV sets the V value that will be used for warn messages.

Logger is the interface that must be implemented by objects that are used for logging by the client. By default the client uses a logger based on the `glog` package, but that can be changed using the `Logger` method of the builder.

Note that the context is optional in most of the methods of the SDK, so implementations of this interface must accept and handle smoothly calls to the Debug, Info, Warn and Error methods where the ctx parameter is nil.
