Method Detail

set

public void set(double value,
                Attributes attributes)

Description copied from interface: DoubleGauge

Records a value with a set of attributes.

Specified by:

set in interface DoubleGauge

Parameters:

value - The current gauge value.

attributes - A set of attributes to associate with the value.

set

public void set(double value,
                Attributes attributes,
                Context context)

Description copied from interface: DoubleGauge

Records a value with a set of attributes.

Specified by:

set in interface DoubleGauge

Parameters:

value - The current gauge value.

attributes - A set of attributes to associate with the value.

context - The explicit context to associate with this measurement.

set

public void set(double increment)

Description copied from interface: DoubleGauge

Set the gauge value.

Specified by:

set in interface DoubleGauge

Parameters:

increment - The current gauge value.

isEnabled

public boolean isEnabled()

Description copied from interface: ExtendedDoubleGauge

Returns true if the gauge is enabled.

This allows callers to avoid unnecessary compute when nothing is consuming the data. Because the response is subject to change over the application, callers should call this before each call to DoubleGauge.set(double), DoubleGauge.set(double, Attributes), or DoubleGauge.set(double, Attributes, Context).

Specified by:

isEnabled in interface ExtendedDoubleGauge
