Declaration

bool IsDebugEnabled { get; }

Property Value

Type	Description
bool

IsErrorEnabled

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

bool IsErrorEnabled { get; }

Property Value

Type	Description
bool

IsFatalEnabled

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.

IsInfoEnabled

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.

Declaration

bool IsInfoEnabled { get; }

Property Value

Type	Description
bool

IsTraceEnabled

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

bool IsTraceEnabled { get; }

Property Value

Type	Description
bool

IsWarnEnabled

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

bool IsWarnEnabled { get; }

Property Value

Type	Description
bool
