Retrieve module information

Retrieve an array of handles for existing modules on a BlackBerry device

>Invoke getModuleHandels().

int handles[] = CodeModuleManager.getModuleHandles();

String name = CodeModuleManager.getModuleName( handles[0]);

Create code modules

Task Steps

Retrieve a handle for a module. >Invoke getModuleHandle() and provide the name of the code module as a parameter.

int handle = CodeModuleManager.getModuleHandle("test_module");

Retrieve specific information about a

module.

> Invoke the methods of the CodeModuleManager class and provide the module handle as a

parameter to these methods.

String name = CodeModuleManager.getModuleName( handle );

String vendor = CodeModuleManager.getModuleVendor( handle );

String description = CodeModuleManager.getModuleDescription( handle );

int version = CodeModuleManager.getModuleVersion( handle );

int size = CodeModuleManager.getModuleCodeSize( handle );

int timestamp = CodeModuleManager.getModuleTimestamp( handle );

Task Steps

Create a module without data. >Invoke createNewModule() and provide the size of the module in bytes as a parameter.

int handle = CodeModuleManager.createNewModule( 3000 );

Create a module with data. >Invoke createNewModule(int, byte[], int), providing the following parameters:

• the length in bytes of the entire module

• the byte array to add to the module

• the length parameter to specify the number of bytes from the byte array to add to the

start of the module

static int createNewModule(int, byte[], int);

Write data into a module. You can write data into a code module in increments, as long as you know the offset at which

to add data.

>Invoke writeNewModule() and provide a byte array of data as a parameter to this

method.

Boolean success = CodeModuleManager.writeNewModule( handle, data,

0, data.length );

Save a module to the BlackBerry® device

database.

>Invoke saveNewModule(int). If the module saves successfully, the method returns one

of the result codes defined in the

CodeModuleManager class.

int result = CodeModuleManager.saveNewModule(handle);
