LSLogger

public protocol LSLogger

Interface to be implemented to consume log from the library.

Instances of implemented classes are obtained by the library through the LSLoggerProvider instance set on LightstreamerClient.setLoggerProvider(...).

  • Checks if this logger is enabled for the Trace level.

    The property should be true if this logger is enabled for Trace events, false otherwise.

    This property is intended to lessen the computational cost of disabled log Trace statements. Note that even if the property is false, Trace log lines may be received anyway by the Trace methods.

    Declaration

    Swift

    var isTraceEnabled: Bool { get }

  • Checks if this logger is enabled for the Debug level.

    The property should be true if this logger is enabled for Debug events, false otherwise.

    This property is intended to lessen the computational cost of disabled log Debug statements. Note that even if the property is false, Debug log lines may be received anyway by the Debug methods.

    Declaration

    Swift

    var isDebugEnabled: Bool { get }

  • Checks if this logger is enabled for the Info level.

    The property should be true if this logger is enabled for Info events, false otherwise.

    This property is intended to lessen the computational cost of disabled log Info statements. Note that even if the property is false, Info log lines may be received anyway by the Info methods.

    Declaration

    Swift

    var isInfoEnabled: Bool { get }

  • Checks if this logger is enabled for the Warn level.

    The property should be true if this logger is enabled for Warn events, false otherwise.

    This property is intended to lessen the computational cost of disabled log Warn statements. Note that even if the property is false, Warn log lines may be received anyway by the Warn methods.

    Declaration

    Swift

    var isWarnEnabled: Bool { get }

  • Checks if this logger is enabled for the Error level.

    The property should be true if this logger is enabled for Error events, false otherwise.

    This property is intended to lessen the computational cost of disabled log Error statements. Note that even if the property is false, Error log lines may be received anyway by the Error methods.

    Declaration

    Swift

    var isErrorEnabled: Bool { get }

  • Checks if this logger is enabled for the Fatal level.

    The property should be true if this logger is enabled for Fatal events, false otherwise.

    This property is intended to lessen the computational cost of disabled log Fatal statements. Note that even if the property is false, Fatal log lines may be received anyway by the Fatal methods.
