  • Method Details

    • initializeIdentityMap

      public void initializeIdentityMap(String className) throws ClassNotFoundException
      This method is used to clear the contents of a particular identity map. Users should be aware that if any of these objects are in use when this action is completed they will lose object identity.
      Parameters:
      className - the fully qualified name of the class for which the identity map should be cleared.
      Throws:
      ClassNotFoundException - thrown then the IdenityMap for that class name could not be found

    • initializeAllIdentityMaps

      public void initializeAllIdentityMaps()
      This method is used to clear the contents of all identity maps. Users should be aware that if any of these objects are in use when this action is completed they will lose object identity.

    • setIdentityMapForClass

      public void setIdentityMapForClass(String className, String identityMapClassType, int maxSize) throws ClassNotFoundException
      This method will be used to set a new type of identity map for a particular class type. If objects of that class type are in use loss of object identity will result. For prevention client may wish to initialize all identity maps first.
      Parameters:
      className - the fully qualified className to set the identity map for.
      identityMapClassType - the fully qualified class name of the new identity map type.
      maxSize - the maximum size to be specified for the new identity map.
      Throws:
      ClassNotFoundException - thrown then the IdenityMap for that class name could not be found

    • refreshProject

      public void refreshProject(String projectFilePath)
      This method used to reset a project in a session. All connected clients will get errors. project must be of the xml type. This attribute will not be stored on a save.
      Parameters:
      projectFilePath - the filename of the project xml file to build the new project from.

    • updateCacheSize

      public void updateCacheSize(String className, int newSize) throws ClassNotFoundException
      This method is used to update the cache size of a particular Identity Map
      Parameters:
      className - the name of the class for which to update the identity map size.
      Throws:
      ClassNotFoundException - thrown then the IdenityMap for that class name could not be found

    • setShouldBindAllParameters

      public void setShouldBindAllParameters(boolean shouldBindAllParameters)
      This method is used to control if All parameters should be bound

    • getShouldBindAllParameters

      public boolean getShouldBindAllParameters()
      Method returns if all Parameters should be bound or not

    • setStringBindingSize

      public void setStringBindingSize(int size)
      Sets the size of strings after which they will be bound into the statement

    • getStringBindingSize

      public int getStringBindingSize()
      Return the size of strings after which will be bound into the statement

    • setUsesBatchWriting

      public void setUsesBatchWriting(boolean usesBatchWriting)
      This method is used to turn on EclipseLink Batch Writing. Please note that toggling this setting while a transaction is open may result in unordered sql statements or loss of statements. Also please note that EclipseLink Batch Writing may not work with all JDBC Drivers

    • getUsesBatchWriting

      public boolean getUsesBatchWriting()

    • setUsesByteArrayBinding

      public void setUsesByteArrayBinding(boolean usesByteArrayBinding)
      This method allows control of whether byte arrays should be bound into the statement or not. Toggling this attribute while an SQL statement is being built, or if you are caching statements, will result in errors.

    • getUsesByteArrayBinding
