ITrendStorageWriter (ITF) ¶ INTERFACE ITrendStorageWriter EXTENDS ITraceMgrPacketReaderClient This interface is implemented by function blocks, that are used to store data from CmpTraceMgr in the trend storage. It is an enhancement of the ITraceMgrPacketReaderClient interface, because for storing data in the trend storage it is necessary, that the ITrendStorageWriter is able to process data coming from an ITraceMgrPacketReader instance. Methods: CanProvideMinMaxTimestamps CreateTrendStorageMetaDataFile GetMinMaxTimestamps Initialize InitializeGetMinMaxTimestamps Structure: CanProvideMinMaxTimestamps (Method) CreateTrendStorageMetaDataFile (Method) GetMinMaxTimestamps (Method) Initialize (Method) InitializeGetMinMaxTimestamps (Method)
ITrendStorageWriter.CanProvideMinMaxTimestamps (METH) ¶ METHOD CanProvideMinMaxTimestamps : BOOL This method indicates, whether the ITrendStorageWriter instance can provide mininum/maximum timestamps (similar to the TrendFbTrendStorageReader instance). In this case the method returns TRUE, otherwise FALSE. InOut: Scope Name Type Return CanProvideMinMaxTimestamps BOOL
ITrendStorageAccessReadOperator2.GradientColorBrightnessRead (METH) ¶ METHOD GradientColorBrightnessRead This method returns the color brightness of the gradient InOut: Scope Name Type Comment Input iWhichVariable INT The 0 based index of the variable within all variables dwValue DWORD The color brightness of the gradient
ITrendStorageAccessReadOperator2.GradientTranspColor1Read (METH) ¶ METHOD GradientTranspColor1Read This method returns first color transparency InOut: Scope Name Type Comment Input iWhichVariable INT The 0 based index of the variable within all variables bValue BYTE The first color transparency of the gradient
ITrendStorageAccessReadOperator2.GradientTranspColor2Read (METH) ¶ METHOD GradientTranspColor2Read This method returns the second color transparency InOut: Scope Name Type Comment Input iWhichVariable INT The 0 based index of the variable within all variables bValue BYTE The second color transparency of the gradient
ITrendStorageAccessReadOperator2.GradientTypeRead (METH) ¶ METHOD GradientTypeRead This method returns the gradient type InOut: Scope Name Type Comment Input iWhichVariable INT The 0 based index of the variable within all variables iValue INT The gradient type
ITrendStorageAccessReadOperator2.GradientUseTwoColorsRead (METH) ¶ METHOD GradientUseTwoColorsRead This method returns if the gradient uses two colors InOut: Scope Name Type Comment Input iWhichVariable INT The 0 based index of the variable within all variables xValue BOOL The gradient uses two colors
ITrendStorageSizeMonitor (ITF) ¶ INTERFACE ITrendStorageSizeMonitor EXTENDS __SYSTEM.IQueryInterface Interface to provide functions about the trend storage. Properties: ForceReorderingFailure LastReorderingTime PercDBLimit RecordSizeFactor ReorderingCount Methods: GetDatabaseFileSize Structure: ForceReorderingFailure (Property) GetDatabaseFileSize (Method) LastReorderingTime (Property) PercDBLimit (Property) RecordSizeFactor (Property) ReorderingCount (Property)
ITrendStorageSizeMonitor.ForceReorderingFailure (PROP) ¶ PROPERTY ForceReorderingFailure : INT This property gets/sets the number of forced reorganization failure, Used only in test
ITrendStorageAccessReadOperator2.CurveTypeRead (METH) ¶ METHOD CurveTypeRead This method returns the curve type of the graph InOut: Scope Name Type Comment Input iWhichVariable INT The 0 based index of the variable within all variables iValue INT The curve type of the graph
