Interface FieldRegistry

All Known Implementing Classes:

FieldRegistry.Default

public interface FieldRegistry

A field registry represents an extendable collection of fields which are identified by their names that are mapped to a given FieldAttributeAppender. Fields can be uniquely identified by their name for a given type since fields are never inherited.

This registry is the counterpart of a MethodRegistry. However, a field registry is implemented simpler since it does not have to deal with complex signatures or inheritance. For the sake of consistency, the field registry follows however a similar pattern without introducing unnecessary complexity.

Method Detail

prepend

FieldRegistry prepend(LatentMatcher<? super FieldDescription> matcher,
                      FieldAttributeAppender.Factory fieldAttributeAppenderFactory,
                      @MaybeNull
                      Object defaultValue,
                      Transformer<FieldDescription> transformer)

Prepends the given field definition to this field registry, i.e. this configuration is applied first.

Parameters:

matcher - The matcher to identify any field that this definition concerns.

fieldAttributeAppenderFactory - The field attribute appender factory to apply on any matched field.

defaultValue - The default value to write to the field or null if no default value is to be set for the field.

transformer - The field transformer to apply to any matched field.

Returns:

An adapted version of this method registry.

compile

FieldRegistry.Compiled compile(TypeDescription instrumentedType)

Prepares the field registry for a given instrumented type.

Parameters:

instrumentedType - The instrumented type.

Returns:

A prepared field registry.
