Constructor Detail

• ModifyAllQuery

  public ModifyAllQuery()

  PUBLIC:

• ModifyAllQuery

  public ModifyAllQuery(java.lang.Class referenceClass)

  PUBLIC: Create a new update all query for the class specified.

• ModifyAllQuery

  public ModifyAllQuery(java.lang.Class referenceClass,
                Expression selectionCriteria)

Method Detail

• isModifyAllQuery

  public boolean isModifyAllQuery()

  PUBLIC: Return true if this is a modify all query.

  Overrides:

  isModifyAllQuery in class DatabaseQuery

• setIsPreparedUsingTempStorage

  public void setIsPreparedUsingTempStorage(boolean isPreparedUsingTempStorage)

  INTERNAL:

• isPreparedUsingTempStorage

  public boolean isPreparedUsingTempStorage()

  INTERNAL:

• clonedQueryExecutionComplete

  protected void clonedQueryExecutionComplete(DatabaseQuery query,
                                  org.eclipse.persistence.internal.sessions.AbstractSession session)

  INTERNAL Used to give the subclasses opportunity to copy aspects of the cloned query to the original query. The clones of all the ModifyAllQueries will be added to modifyAllQueries for validation.

  Overrides:

  clonedQueryExecutionComplete in class DatabaseQuery

• executeInUnitOfWork

  public java.lang.Object executeInUnitOfWork(org.eclipse.persistence.internal.sessions.UnitOfWorkImpl unitOfWork,
                                     org.eclipse.persistence.internal.sessions.AbstractRecord translationRow)
                                       throws DatabaseException,
                                              OptimisticLockException

  INTERNAL: Override query execution where Session is a UnitOfWork.

  If there are objects in the cache return the results of the cache lookup.

  Overrides:

  executeInUnitOfWork in class DatabaseQuery

  Parameters:

  unitOfWork - - the session in which the receiver will be executed.

  translationRow - - the arguments

  Returns:

  An object, the result of executing the query.

  Throws:

  DatabaseException - - an error has occurred on the database.

  OptimisticLockException - - an error has occurred using the optimistic lock feature.

• getCacheUsage

  public int getCacheUsage()

  PUBLIC: Return the cache usage for this query.

• getExpressionBuilder

  public ExpressionBuilder getExpressionBuilder()

  PUBLIC: Get the expression builder which should be used for this query. This expression builder should be used to build all expressions used by this query.

• setExpressionBuilder

  public void setExpressionBuilder(ExpressionBuilder builder)

  INTERNAL Sets the default expression builder for this query.

• getReferenceClassName

  public java.lang.String getReferenceClassName()

  INTERNAL: Return the name of the reference class of the query. Used by the Mapping Workbench to avoid classpath dependencies

  Overrides:

  getReferenceClassName in class DatabaseQuery

• getReferenceClass

  public java.lang.Class getReferenceClass()

  PUBLIC: Return the reference class for this query.

  Overrides:

  getReferenceClass in class DatabaseQuery

• invalidateCache

  protected void invalidateCache()

  INTERNAL: Invalid the cache, that is, those objects in the cache that were affected by the query.

• mergeChangesIntoSharedCache

  public void mergeChangesIntoSharedCache()

  INTERNAL: After execution we need to merge the changes into the shared cache, unless the query has been tagged to bypass on the store.

• setCacheUsage

  public void setCacheUsage(int cacheUsage)

  PUBLIC: Set the level of cache support for this query, either NONE or INVALIDATE.

• setReferenceClass

  public void setReferenceClass(java.lang.Class referenceClass)

  PUBLIC: Set the reference class this query.

• setReferenceClassName

  public void setReferenceClassName(java.lang.String className)

  INTERNAL: Set the class name of the reference class of this query. Used by the Mapping Workbench to avoid classpath dependencies.

• setShouldDeferExecutionInUOW

  public void setShouldDeferExecutionInUOW(boolean shouldDeferExecutionInUOW)

  PUBLIC: Set a flag indicating whether execution should be deferred in UOW until commit.

• shouldDeferExecutionInUOW

  public boolean shouldDeferExecutionInUOW()

  PUBLIC: Indicates whether execution should be deferred in UOW until commit.

• shouldInvalidateCache

  protected boolean shouldInvalidateCache()

  INTERNAL:

• initializeDefaultBuilder

  protected void initializeDefaultBuilder()

  INTERNAL: Initialize the expression builder which should be used for this query. If there is a where clause, use its expression builder, otherwise generate one and cache it. This helps avoid unnecessary rebuilds.

• initializeQuerySpecificDefaultBuilder

  protected void initializeQuerySpecificDefaultBuilder()

  INTERNAL: Initialize the expression builder which should be used for this query. If there is a where clause, use its expression builder. If after this method defaultBuilder is still null, then initializeDefaultBuilder method will generate and cache it.
