Method Details

process

public Attributes process(Attributes incoming,
 Context context)

Description copied from class: AttributesProcessor

Manipulates a set of attributes, returning the desired set.

Specified by:

process in class AttributesProcessor

Parameters:

incoming - Attributes associated with an incoming measurement.

context - The context associated with the measurement.

usesContext

public boolean usesContext()

Description copied from class: AttributesProcessor

If true, this ensures the `Context` argument of the attributes processor is always accurate. This will prevents bound instruments from pre-locking their metric-attributes and defer until context is available.

Specified by:

usesContext in class AttributesProcessor

then

public AttributesProcessor then(AttributesProcessor other)

Description copied from class: AttributesProcessor

Joins this attribute processor with another that operates after this one.

Overrides:

then in class AttributesProcessor

prepend

AttributesProcessor prepend(AttributesProcessor other)

toString

public String toString()

Overrides:

toString in class Object
