Detailed Description

Waveform descriptor.

Definition at line 23 of file ecvWaveform.h.

Constructor & Destructor Documentation

WaveformDescriptor()

WaveformDescriptor::WaveformDescriptor

(

)

Default constructor.

Member Function Documentation

fromFile()

bool WaveformDescriptor::fromFile ( QFile &  in, short  dataVersion, int  flags, LoadedIDMap &  oldToNewIDMap  )

overridevirtual

Loads data from binary stream.

Parameters

in	input file (already opened)
dataVersion	file version (for version-specific deserialization)
flags	deserialization flags (see ccSerializableObject::DeserializationFlags)
oldToNewIDMap	map to link old IDs with new IDs

Returns

success

Note: When implementing, use dataVersion checks to handle different

versions:

• if (dataVersion >= X) { read new field } else { use default value } This ensures forward compatibility with older file formats.

Reimplemented from ccSerializableObject.

isSerializable()

bool WaveformDescriptor::isSerializable ( ) const

inlineoverridevirtual

Returns whether object is serializable of not.

Reimplemented from ccSerializableObject.

Definition at line 35 of file ecvWaveform.h.

minimumFileVersion()

short WaveformDescriptor::minimumFileVersion ( ) const

overridevirtual

Returns the minimum file version required to save this instance.

To be overridden by subclasses to indicate their minimum required version. This enables the system to determine:

• Forward compatibility: newer software can read older files (dataVersion check in fromFile)
• Backward compatibility: determine minimum version needed to save current data

  Returns

  minimum file version required for this object

Implements ccSerializableObject.

operator!=()

bool WaveformDescriptor::operator!=

(

const WaveformDescriptor &

d

)

const

Difference operator.

operator==()

bool WaveformDescriptor::operator== ( const WaveformDescriptor &  d ) const

inline

Equivalence operator.

Definition at line 32 of file ecvWaveform.h.

toFile()

bool WaveformDescriptor::toFile ( QFile &  out, short  dataVersion  ) const

overridevirtual

Saves data to binary stream.

Parameters

out	output file (already opened)
dataVersion	target file version (for forward/backward compatibility)

Returns

success

Reimplemented from ccSerializableObject.
