Summary
Returns all IEEE Symbol objects whose Symbol property complies with the Query.
Syntax
IeeeSymbol = IeeeSymbol_String
IeeeSymbol <> IeeeSymbol_String
IeeeSymbol_String must be one of the following strings:
- 'Active Low Input'
- 'Active Low Output'
- 'Analog Signal In'
- 'And'
- 'Bidirectional Signal Flow'
- 'Clock'
- 'Delay'
- 'Digital Signal In'
- 'Dot'
- 'GreaterThan/Equal'
- 'Group Bin'
- 'Group Line'
- 'High Current'
- 'Hiz'
- 'Input/Output'
- 'Invertor'
- 'Left Right Signal Flow'
- 'Less Than/Equal'
- 'No Symbol'
- 'Not Logic Connection'
- 'Open Collector'
- 'Open Collector Pull Up'
- 'Open Emitter'
- 'Open Emitter Pull Up'
- 'Open Output'
- 'Or'
- 'PiSymbol'
- 'Postponed Output'
- 'Pulse'
- 'Right Left Signal Flow'
- 'Schmitt'
- 'Shift Left'
- 'Shift Right'
- 'Sigma'
- 'Xor'
Example Usage
IeeeSymbol = 'Left'
Returns all IEEE Symbol objects whose Symbol property is Left.
IeeeSymbol <> 'Center'
Returns all objects except IEEE Symbol objects whose Symbol property is Center.
IsSymbol && IeeeSymbol <> 'Open Output'
Returns all IEEE Symbol objects except those whose Symbol property is Open Output.
Tips
- The single quote characters (') at the start and end of
IeeeSymbol_Stringare mandatory. - The Symbol property is only defined for IEEE Symbol objects.
