Member Functions Documentation

DoExternalizeL(RWriteStream &)

void

DoExternalizeL

(

RWriteStream &

aStream

)

const [protected, pure virtual]

Externalize method that subclass must implement.

Parameters

RWriteStream & aStream

Stream to which the object should be externalized.

DoInternalizeL(RReadStream &)

void

DoInternalizeL

(

RReadStream &

aStream

)

[protected, pure virtual]

Internalize method that subclass must implement.

Parameters

RReadStream & aStream

Stream from which the object should be internalized.

ExternalizeL(RWriteStream &)

IMPORT_C void

ExternalizeL

(

RWriteStream &

aStream

)

const

Externalizes the trigger condition object's details and attributes to stream.

The presence of this function means that the standard templated operator<<() ( defined in s32strm.h ) is available to externalize objects of this class.

Parameters

RWriteStream & aStream

Stream to which the object should be externalized.

InternalizeL(RReadStream &)

IMPORT_C void

InternalizeL

(

RReadStream &

aStream

)

Internalizes the trigger condition object's details and attributes from stream.

The presence of this function means that the standard templated operator>>() ( defined in s32strm.h ) is available to internalize objects of this class.

Parameters

RReadStream & aStream

Stream from which the object should be internalized.

Type()
