CompiledQuery
public interface CompiledQuery (Code)
A query compiled from a QueryDetails instance.




Method Summary
public  int[]getClassIndexes()

public  int[]getEvictionClassBits()
     Return bitmapped array of the class indexes involved in this query in some way.
public  intgetFirstThisIndex()
     The index of the first occurance of 'this' in the projection.
public  intgetId()
     Get the unique ID assigned to this CompiledQuery.
public  QueryDetailsgetQueryDetails()
     Return the QueryDetails this query was compiled from.
public  int[]getResultTypeCodes()
     The typeCode of each column or null if this is not a projection query.
public  booleanisDefaultResult()
     If this query returns default results.
public  booleanisProjectionQuery()
     Is this a non default projection query.
public  booleanisUnique()
     If this is a query with a single/unique result.
public  voidsetId(int id)
     Give this query an ID.



Method Detail
getClassIndexes
public int[] getClassIndexes()(Code)
Get the indexes of all of the classes involved in some way. This is used to check query cache eviction and to trigger flushing.



getEvictionClassBits
public int[] getEvictionClassBits()(Code)
Return bitmapped array of the class indexes involved in this query in some way. that will cause the results of this query to be evicted when their instances are modified. Each class index has one bit in this array.



getFirstThisIndex
public int getFirstThisIndex()(Code)
The index of the first occurance of 'this' in the projection. If not then return -1.



getId
public int getId()(Code)
Get the unique ID assigned to this CompiledQuery.



getQueryDetails
public QueryDetails getQueryDetails()(Code)
Return the QueryDetails this query was compiled from. This method may return null if this information is not available.



getResultTypeCodes
public int[] getResultTypeCodes()(Code)
The typeCode of each column or null if this is not a projection query.
See Also:   com.versant.core.metadata.MDStatics



isDefaultResult
public boolean isDefaultResult()(Code)
If this query returns default results. ie The result will be a collection of managed instances.



isProjectionQuery
public boolean isProjectionQuery()(Code)
Is this a non default projection query. This will return false for the default projection.



isUnique
public boolean isUnique()(Code)
If this is a query with a single/unique result.



setId
public void setId(int id)(Code)
Give this query an ID. This is used by CompiledQueryCache to assign unique IDs to CompiledQuery's.
