IDerivedStateComputerParticipant (1C:Enterprise Development Tools 1.24.0-SNAPSHOT API)

All Known Implementing Classes:

CompoundDerivedStateComputerParticipant
```
public interface IDerivedStateComputerParticipant
```
A derived state computer participant allows to extend derived state computing.
It is up to derived state computer to decide when trigger participants to install or discard derived state.

Implementors should keep in mind that they share the resource set with other derived state computer participants thus you shall not modify the state of the given resource set besides adding or removing resources.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`discardDerivedState(org.eclipse.xtext.resource.DerivedStateAwareResource resource)`	Discards derived state
`void`	`installDerivedState(org.eclipse.xtext.resource.DerivedStateAwareResource resource, boolean preLinkingPhase)`	Installs derived state

- Method Detail
  - installDerivedState
```
void installDerivedState(org.eclipse.xtext.resource.DerivedStateAwareResource resource,
                         boolean preLinkingPhase)
```
    Installs derived state
    
    Parameters:
    
    resource - the resource to install derived state on
    
    preLinkingPhase - whether the call is done in a pre-linking phase. During this phase clients may not do linking which relies on indexed information, because the index might not be fully computed yet.
  - discardDerivedState
```
void discardDerivedState(org.eclipse.xtext.resource.DerivedStateAwareResource resource)
```
    Discards derived state
    
    Parameters:
    
    resource - the resource to discard derived state on
