Interface IIndexSlice

All Known Implementing Classes:

IndexSlice

public interface IIndexSlice

Special interface for index slice. This interface provides method for adding, deleting and finding index element in slice.
Also this interface provides special mechanism of identification type of index slice by ISliceFilter - see method getPredicate()

Method Summary

Modifier and Type	Method	Description
boolean	addItem(long id, org.eclipse.xtext.resource.IEObjectDescription item)	Tries to add index element to index slice
Set<Long>	getItems()	Gets unique ids of index elements contained in this index slice
ISliceFilter	getPredicate()	Gets special ISliceFilter that determines elements in this index slice.
boolean	removeItem(long id)	Tries to delete index element from index slice

Method Details

getItems

Set<Long> getItems()

Gets unique ids of index elements contained in this index slice

Returns:

unique ids of index elements contained in this index slice, never null

addItem

boolean addItem(long id,
 org.eclipse.xtext.resource.IEObjectDescription item)

Tries to add index element to index slice

Parameters:

id - special unique id for adding index element

item - index element for adding to index slice, can't be null

Returns:

true if index element was added to slice, false if index element is not supported of this index slice. If index already has contained element with the same id then false will be returned and index won't change Supporting index items are determined by predicate from getPredicate()

removeItem

boolean removeItem(long id)

Tries to delete index element from index slice

Parameters:

id - special unique id for deleting index element

Returns:

true if item was succeeded deleted, false otherwise

getPredicate

ISliceFilter getPredicate()

Gets special ISliceFilter that determines elements in this index slice. This ISliceFilter is id of slice type

Returns:

special ISliceFilter that determines elements in this index slice, can't be null
