IsChild(TUsbGenericDescriptor &)

TBool IsChild(TUsbGenericDescriptor &aPotentialChild)[virtual]

This function determines whether the given USB descriptor is a child of the descriptor the method is called on. The implementation may be specialised for each type of descriptor to ensure the tree is correctly built up.

Parameters

TUsbGenericDescriptor & aPotentialChildThe USB descriptor that is being queried to see if it is a child.

IsParent(TUsbGenericDescriptor &)

TBool IsParent(TUsbGenericDescriptor &aPotentialParent)[virtual]

Parameters

TUsbGenericDescriptor & aPotentialParent

IsPeer(TUsbGenericDescriptor &)

TBool IsPeer(TUsbGenericDescriptor &aPotentialPeer)[virtual]

Parameters

TUsbGenericDescriptor & aPotentialPeer

ParseL(TPtrC8 &, TUsbGenericDescriptor *)

TUsbInterfaceAssociationDescriptor *ParseL(TPtrC8 &aUsbDes,
TUsbGenericDescriptor *aPreviousDesc
)[static]

Parameters

TPtrC8 & aUsbDes
TUsbGenericDescriptor * aPreviousDesc
