class TFindLogicalDevice : public TFindHandleBase;
Searches for LDD factory objects by pattern matching against the names of LDD factory objects.
An LDD factory object is an instance of a DLogicalDevice
derived class.
The match pattern can be set into this object at construction; it can also be changed at any time after construction by using
TFindHandleBase::Find(const TDesC &)
.
After construction, call TFindLogicalDevice::Next(TFullName &)
repeatedly to find successive LDD factory objects whose names match the current pattern. A successful call to TFindLogicalDevice::Next(TFullName &)
means that a matching LDD factory object has been found.
The name of an LDD factory object is set by its Install() member function as part of the construction process.

Defined in TFindLogicalDevice
:
Next(TFullName &)
Finds the full name of the next LDD factory object which matches the match patte...TFindLogicalDevice()
Constructs the LDD factory object with a default match pattern.TFindLogicalDevice(const TDesC &)
Constructs the LDD factory object with a specified match pattern.Inherited from TFindHandleBase
:
Find(const TDesC &)
Sets a new match pattern.TFindHandleBase(const TDesC &)
Constructor with match pattern.inline TFindLogicalDevice();
Constructs the LDD factory object with a default match pattern.
The default match pattern, as implemented by the base class, is the single character "*".
A new match pattern can be set after construction by calling the TFindHandleBase::Find(const TDesC &)
member function of the TFindHandleBase
base class.
TFindHandleBase::Find(const TDesC &)
Sets a new match pattern.inline TFindLogicalDevice(const TDesC &aMatch);
Constructs the LDD factory object with a specified match pattern.
A new match pattern can be set after construction by calling TFindHandleBase::Find(const TDesC &)
.

TFindHandleBase::Find(const TDesC &)
Sets a new match pattern.IMPORT_C TInt Next(TFullName &aResult);
Finds the full name of the next LDD factory object which matches the match pattern.
