Method Details

getNestedGroups

@Nonnull
List<EntryGroupData> getNestedGroups(@Nonnull
 EntryGroupData root)

Flatten group tree and return it as a plain list of groups.

The method keeps item order unchanged: first goes root item, then its first child, then the children of that child and so forth.

Parameters:

root - node to start collecting from

Returns:

list, that includes the node and all its descendants

Throws:

IllegalArgumentException - is root is null

getLeaves

@Nonnull
List<EntryGroupData> getLeaves(@Nonnull
 EntryGroupData root)

Returns all leaf nodes of group tree, preventing their natural order.

Parameters:

root - root node of group tree

Returns:

leaf nodes

Throws:

IllegalArgumentException - if root is null

getGroup

@Nonnull
EntryGroupData getGroup(@Nonnull
 AbstractOrderData order,
 @Nonnull
 Integer groupNumber)

Returns EntryGroupData by groupNumber from given order

Parameters:

groupNumber - number of the group to search for

order - order containing entry group trees

Returns:

EntryGroupData with given groupNumber from the order

Throws:

IllegalArgumentException - if no group with given groupNumber in the order

IllegalArgumentException - if order is null

IllegalArgumentException - if order.rootGroups is null

IllegalArgumentException - if groupNumber is null

getGroup

@Nonnull
EntryGroupData getGroup(@Nonnull
 AbstractOrderData order,
 @Nonnull
 Collection<Integer> groupNumbers,
 @Nonnull
 GroupType groupType)

Searches for entry group which is a type of groupType and which number belongs to the groupNumbers.

Parameters:

order - order what is expected to contain the desired group

groupNumbers - possible group numbers. Usually are taken from OrderEntryData.getEntryGroupNumbers()

groupType - desired group type

Returns:

group

Throws:

IllegalArgumentException - if group was not found or any of the args is invalid

findMaxGroupNumber

int findMaxGroupNumber(List<EntryGroupData> roots)

Returns max value of EntryGroupData#groupNumber.

Parameters:

roots - root groups

Returns:

maximum group number among the whole forest
