You may need to load the same values that Structure shows on the=
Structure Board, especially if it's a total value, progress value or other=
Structure-specific value. This is done via StructureAttributeSe=
rvice
.
One of the core concepts in Structure is the Attribute abstraction. An a= ttribute is something that can provide a value of specific type and meaning= for any row in a forest.
For example, a "Summary" attribute would produce the value of Summary fi= eld for issues, the name of a folder for folders and a person's full name f= or users. Some attributes may be applicable only to certain item types and = would provide empty value for all other items.
Besides item-based attributes, which provide values that depend only on = the item in the forest, there are forest-based attributes, which are calcul= ated based on the whole forest and items in it.
Forests and Attributes are two main concepts that make up the Structure = grid. Looking at the Structure Board, you see Forest in the vertical direct= ion =E2=80=93 rows and hierarchy are taken from Forest, and you see Attribu= tes in the horizontal direction =E2=80=93 all columns load Attributes from = the server and display those values.
Let's assume that, after Reading Structure Content, you have StructureCompo=
nents
instance and an instance of ForestSpec
=
for a forest. We can read a number of attributes for a number of rows by go=
ing to StructureAttributeService.
The service accepts multiple attribute specs in one request. If you need= several attributes calculated =E2=80=93 it's better to do that in one= request.
List<= ;AttributeSpec<?>> attributeSet =3D new ArrayList<>(); attributeSet.add(CoreAttributeSpecs.KEY); attributeSet.add(CoreAttributeSpecs.SUMMARY); attributeSet.add(CoreAttributeSpecs.TOTAL_REMAINING_ESTIMATE);=20
CoreAttributeSpecs
class and its parent class, S=
haredAttributeSpecs
, contain some of the most popular attributes.
It's likely that you'll need to build you own attribute specification. F= or example, to address a numeric JIRA custom field and calculate total of t= hat field based on sub-issues, you'll need the following.
Attribu= teSpec<Number> customField =3D AttributeSpecBuilder.create("customfield", ValueFormat.NUMBER).params().s= et("fieldId", 10000).build(); AttributeSpec<Number> customFieldTotal =3D AttributeSpecBuilder.create(CoreAttributeSpecs.Id.SUM, ValueFormat.NUMBER= ).params().setAttribute(customField).build(); attributeSet.add(customFieldTotal);=20
For example, this could be all rows in that structure.
LongLis= t rows =3D myStructureComponents.getForestService().getForestSource(forestS= pec).getLatest().getForest().getRows();=20
If you need to create a LongList
manually, use LongAr=
ray
implementation.
StructureAttributeService
This service calculates a matrix of values for each row and attribute yo= u specify.
RowValu= es values =3D myStructureComponents.getAttributeService().getAttributeValue= s(forestSpec, rows, attributeSet);=20
There is a variation of getAttributeValues()
method that ac=
cepts a Forest
, rather than ForestSpec
. It is rec=
ommended to use the variant that accepts ForestSpec
whenever p=
ossible, because that variant uses caching.
The returned object contains values for all pairs of requested row and r= equested attribute.
for (Lo= ngIterator ii : rows) { String key =3D values.get(ii.value(), CoreAttributeSpecs.KEY); Number total =3D values.get(ii.value(), customFieldTotal); ... }=20
