Method Detail

getObject

public static <DBUTL extends DBUInterface> DBUTL getObject(java.lang.Class<DBUTL> objcls)

Returns the database utility object for the given object class with a null servlet or thread context. Allows for properties to be defined that indicate which class actually gets created for the class that is passed to the method.

Example:
dbutl.MyObject.class=com.dpslink.somepackage.YourObject
If MyObject.class is passed to this method, the class actually created would be YourObject. If no matching property exists for MyObject.class, then MyObject would be created.

CLASSES THAT HAVE ACCESS TO A SERVLET CONTEXT SHOULD LIKELY NOT INVOKE THIS METHOD BUT SHOULD INSTEAD INVOKE A METHOD CONTAINED WITHIN THE CONTEXT.

Parameters:

objcls - (Class) The class for the desired object.

Returns:

DBUInterface - The database utility object or null if unable to create the requested object. If no object class is defined in properties, the object for the supplied class is created.

getObject

public static <DBUTL extends DBUInterface> DBUTL getObject(java.lang.Class<DBUTL> objcls,
                                                           FlashServletContext ctx)

Returns the database utility object for the given object class with the given servlet or thread context. Allows for properties to be defined that indicate which class actually gets created for the class that is passed to the method.

Example:
dbutl.MyObject.class=com.dpslink.somepackage.YourObject
If MyObject.class is passed to this method, the class actually created would be YourObject. If no matching property exists for MyObject.class, then MyObject would be created.

CLASSES THAT HAVE ACCESS TO A SERVLET CONTEXT SHOULD LIKELY NOT INVOKE THIS METHOD BUT SHOULD INSTEAD INVOKE A METHOD CONTAINED WITHIN THE CONTEXT.

Parameters:

objcls - (Class) The class for the desired object.

ctx - (FlashServletContext) The current servlet or thread context.

Returns:

DBUInterface - The database utility object or null if unable to create the requested object. If no object class is defined in properties, the object for the supplied class is created.

getTranslator

public static FileNameTranslator getTranslator()

Returns the file name translator object for the configured file name translator class (dbutl.FileNameTranslator.class). Initializes the object by setting its configured arguments (dbutl.FileNameTranslator.args).

Returns:

FileNameTranslator - The object for the configured class or null if no class is configured (which is ok) or if unable to create the object for the configured class.
