Method Details

add

public void add(double increment,
 Attributes attributes,
 Context context)

Description copied from interface: DoubleUpDownCounter

Records a value with a set of attributes.

Specified by:

add in interface DoubleUpDownCounter

Parameters:

increment - The increment amount. May be positive, negative or zero.

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

context - The explicit context to associate with this measurement.

add

public void add(double increment,
 Attributes attributes)

Description copied from interface: DoubleUpDownCounter

Records a value with a set of attributes.

Note: This may use Context.current() to pull the context associated with this measurement.

Specified by:

add in interface DoubleUpDownCounter

Parameters:

increment - The increment amount. May be positive, negative or zero.

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

add

public void add(double increment)

Description copied from interface: DoubleUpDownCounter

Records a value.

Note: This may use Context.current() to pull the context associated with this measurement.

Specified by:

add in interface DoubleUpDownCounter

Parameters:

increment - The increment amount. May be positive, negative or zero.

isEnabled

public boolean isEnabled()

Description copied from interface: ExtendedDoubleUpDownCounter

Returns true if the up down counter 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 DoubleUpDownCounter.add(double), DoubleUpDownCounter.add(double, Attributes), or DoubleUpDownCounter.add(double, Attributes, Context).
