Method Details

record

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

Description copied from interface: DoubleHistogram

Records a value with a set of attributes.

Specified by:

record in interface DoubleHistogram

Parameters:

value - The amount of the measurement. MUST be non-negative.

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

context - The explicit context to associate with this measurement.

record

public void record(double value,
 Attributes attributes)

Description copied from interface: DoubleHistogram

Records a value with a set of attributes.

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

Specified by:

record in interface DoubleHistogram

Parameters:

value - The amount of the measurement. MUST be non-negative.

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

record

public void record(double value)

Description copied from interface: DoubleHistogram

Records a value.

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

Specified by:

record in interface DoubleHistogram

Parameters:

value - The amount of the measurement. MUST be non-negative.

isEnabled

public boolean isEnabled()

Description copied from interface: ExtendedDoubleHistogram

Returns true if the histogram 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 DoubleHistogram.record(double), DoubleHistogram.record(double, Attributes), or DoubleHistogram.record(double, Attributes, Context).

Specified by:

isEnabled in interface ExtendedDoubleHistogram
