PropertyPath.PathSegment

public class PropertyPath.PathSegment


A segment of a PropertyPath, which includes the name of the property and a 0-based index into this property.

If the property index is not set to NON_REPEATED_CARDINALITY, this represents a schema property with the "repeated" cardinality, or a path like "foo[1]". Otherwise, this represents a schema property that could have any cardinality, or a path like "foo".

static @NonNull PropertyPath.PathSegment
create(@NonNull String propertyName, int propertyIndex)

@NonNull PropertyPath.PathSegment

A new PathSegment

Throws
java.lang.IllegalArgumentException
