Interface InclusionConfigurer

All Known Implementing Classes:

InclusionService

public interface InclusionConfigurer

Allows to in- or exclude nodes based on property name, object type, category or location in the object graph. Excluded nodes will not be compared, to make sure their accessors won't get called. This is useful in cases where getters could throw exceptions under certain conditions or when certain accessors are expensive to call or simply not relevant for the use-case.

In combination with categories this allows to define sub-sets of properties, in order to compare only relevant parts of an object (e.g. exclude all properties marked as _metadata_.)

Method Detail

include

InclusionConfigurer.ToInclude include()

Includes elements (and implicitly all their children) based on certain criteria, unless their parent element is excluded.

exclude

InclusionConfigurer.ToExclude exclude()

resolveUsing

InclusionConfigurer resolveUsing(InclusionResolver resolver)

Registers a custom InclusionResolver. Some objects may not be relevant or suitable for the comparison process. Using an InclusionResolver is a powerful and flexible way to detect and exclude those objects.

Keep in mind that every single node in the object graph will be checked against each and every registered InclusionResolver. If performance is important to you, make sure that calling its methods is as cheap as possible.
