Method Detail

iterator

Iterator<ResolvedSegment> iterator()

Returns an iterator over ResolvedSegment(s).

Specified by:

iterator in interface Iterable<ResolvedSegment>

Returns:

an Iterator

reverse

Iterator<ResolvedSegment> reverse()

Returns a reverse order iterator over ResolvedSegment(s), starting from the target segment.

Returns:

an Iterator

rootEntity

CdsEntity rootEntity()

Returns the CdsEntity that is the root of the ref.

Returns:

the root CdsEntity

rootKeys

Map<String,Object> rootKeys()

Returns the element name to value mapping for the key elements of the CdsEntity that is the root of the ref. Extracts the key values, i.e. the values of the key elements of the entity that is the root of the ref. If the filter does not uniquely restrict a key element to a particular value, the element's name is mapped to null.

Returns:

a map relating key element names to key values

targetKeys

Map<String,Object> targetKeys()

Returns the element name to value mapping for the key elements of the CdsEntity that is targeted by the ref. Extracts the key values, i.e. the values of the key elements to the entity targeted by the ref and optionally the statement's where condition. If the combined filter does not uniquely restrict a key element to a particular value, the element's name is mapped to null.

Returns:

a map relating key element names to key values

targetEntity

CdsEntity targetEntity()

Returns the CdsEntity targeted by the ref.

Returns:

the target CdsEntity
