Field Detail

checkSecurity

public final boolean checkSecurity

Flag is true to check the security rules for each access to objects of this class. The rules will be checked in local db access only (i.e. the check will be applied already at the RMI-side *before* the data is leaving the client!) Because this check can be somewhat time consuming, it's turned off by default. The flag cannot be changed at runtime anymore!

normTextStatementId

public int normTextStatementId

prepared statement ID for AppDbObject.selectByNormText(java.lang.String)

allInContextStatementId

public int allInContextStatementId

prepared statement ID for AppDbObject.selectAllInContext()

normTextCursorStatementId

public int normTextCursorStatementId

prepared statement ID for AppDbObject.selectByNormTextCursor(java.lang.String)

allInContextCursorStatementId

public int allInContextCursorStatementId

prepared statement ID for AppDbObject.selectAllInContextCursor()

updateEditedByStatementId

public int updateEditedByStatementId

prepared statement ID for AppDbObject.updateEditedBy(java.sql.Timestamp, long, java.sql.Timestamp)

updateEditedByOnlyStatementId

public int updateEditedByOnlyStatementId

prepared statement ID for AppDbObject.updateEditedByOnly()

selectEditedByStatementId

public int selectEditedByStatementId

prepared statement ID for select in AppDbObject.updateEditedBy(java.sql.Timestamp, long, java.sql.Timestamp)

transferEditedByStatementId

public int transferEditedByStatementId

prepared statement ID for AppDbObject.transferEditedBy(long)

Constructor Detail

AppDbObjectClassVariables

public AppDbObjectClassVariables(Class<? extends AppDbObject> clazz,
                                 String tableName,
                                 String singleName,
                                 String multiName,
                                 boolean checkSecurity)

constructs a classvariable

Parameters:

clazz - is the class of the derived DbObject

tableName - is the SQL tablename

singleName - text for a single object

multiName - text for multiple objects

checkSecurity - is true to check the READ/WRITE-Security on each access.

AppDbObjectClassVariables

public AppDbObjectClassVariables(Class<? extends AppDbObject> clazz,
                                 String tableName,
                                 String singleName,
                                 String multiName)

Constructs a classvariable. By default, the security check is turned on for servers. It can be overwridden by the property "checksecurity=on|off|true|false|enabled|disabled|0|1" in the class property file.

Parameters:

clazz - is the class of the derived DbObject

tableName - is the SQL tablename

singleName - text for a single object

multiName - text for multiple objects

Method Detail

isReadAllowed

public boolean isReadAllowed(ContextDb contextDb)

Check the read security for this class. The implementation checks that the class rules will accept and that no object rule denies.

Notice that Security objects are always readable!

Parameters:

contextDb - the current context, null = all

Returns:

false if operation (select) is denied.

isReadAllowed

public boolean isReadAllowed()

Check the read security for this class in all contexts.

Returns:

false if operation (select) is denied.

isWriteAllowed

public boolean isWriteAllowed(ContextDb contextDb)

Check the write security for this class. The implementation checks that the class rules will accept and that no object rule denies.

Parameters:

contextDb - the current context, null = all

Returns:

false if operation (delete, update or insert) is denied.

isWriteAllowed

public boolean isWriteAllowed()

Check the write security for this class in all contexts.

Returns:

false if operation (delete, update or insert) is denied.

isReadAllowed

public boolean isReadAllowed(AppDbObject object)

Check the read security for a single object.

Notice that Security objects are always readable!

Parameters:

object - the object to check the security rules for.

Returns:

false if operation (select) is denied.

isWriteAllowed

public boolean isWriteAllowed(AppDbObject object)

Check the write security for a single object.

Parameters:

object - the object to check the security rules for.

Returns:

false if operation (delete, update or insert) is denied.

isReadAllowed

public <T extends AppDbObject,C extends Collection<T>> C isReadAllowed(C objects)

Checks the read security for a collection of objects of this class.
The returned collection is of the same type as the original collection. Notice that this method is provided for applications that circumvent readFromResultsetWrapper() somehow (which checks the read permission). Tentackle is not using this method.

Notice that Security objects are always readable!

Type Parameters:

T - AppDbObject class

C - Collection class

Parameters:

objects - the collection to check the security rules for.

Returns:

the objects with permission accepted.

isWriteAllowed

public <T extends AppDbObject,C extends Collection<T>> C isWriteAllowed(C objects)

Checks the write security for a collection of objects of this class.
The returned collection is of the same type as the original collection. Notice that this method is provided for applications that circumvent deleteObject, updateObject or insertObject somehow (all of them check the write permission). Tentackle is not using this method. Furthermore, special care must be taken for "deleteBy..." methods that delete objects by an sql-statement via "DELETE ...".

Type Parameters:

T - AppDbObject class

C - Collection class

Parameters:

objects - the collection to check the security rules for.

Returns:

the objects with permission accepted.
