iUid

TInt32

iUid

The 32-bit integer UID value.

Member Function Documentation

Name ( )

IMPORT_C TUidName

Name

(

const

Generates and returns the standard text form of the UID.

The resulting text has the form:

[12345678]

The function always generates 10 characters, where the first and last characters are open and close square brackets enclosing exactly 8 hexadecimal digits (padded to the left with zeroes, if necessary).

Return Value: A modifiable descriptor containing the standard text format of the UID.

)

[static, inline]

Constructs the TUid object from a 32-bit integer.

Parameters
aUid	The 32-bit integer value from which the TUid object is to be constructed.

Return Value: The constructed TUid object.

operator!= ( const TUid & )

IMPORT_C TBool

operator!=

(

const TUid &

aUid

)

const

Compares two UIDs for inequality.

Parameters
aUid	The UID to be compared with this UID.

Return Value: True, if the two UIDs are unequal; false otherwise.

operator== ( const TUid & )

IMPORT_C TBool

operator==

(

const TUid &

aUid

)

const

Compares two UIDs for equality.

Parameters
aUid	The UID to be compared with this UID.

Return Value: True, if the two UIDs are equal; false otherwise.
