Constructors

Constructor	Description
constructor()	Default Constructor.

Properties

Property	Type	Description
ignoreError	boolean	Indicates whether errors encountered while calculating formulas should be ignored. The error may be unsupported function, external links, etc. The default value is true.
recursive	boolean	Indicates whether calculate the dependent cells recursively when calculating one cell and it depends on other cells. The default value is true.
customEngine	AbstractCalculationEngine	The custom formula calculation engine to extend the default calculation engine of Aspose.Cells.
calcStackSize	number	The stack size for calculating cells recursively. Default value is 200.
precisionStrategy	CalculationPrecisionStrategy	Specifies the strategy for processing precision of calculation.
linkedDataSources	Workbook[]	Specifies the data sources for external links used in formulas.
characterEncoding	EncodingType	Specifies the encoding used for encoding/decoding characters when calculating formulas. For functions such as CHAR, CODE, the calculated result depends on the region settings and default charset of the environment. With this property user can specify the proper encoding used for those function to get the expected result.

constructor()

Default Constructor.

constructor();

ignoreError

Indicates whether errors encountered while calculating formulas should be ignored. The error may be unsupported function, external links, etc. The default value is true.

ignoreError : boolean;

recursive

Indicates whether calculate the dependent cells recursively when calculating one cell and it depends on other cells. The default value is true.

recursive : boolean;

customEngine

The custom formula calculation engine to extend the default calculation engine of Aspose.Cells.

customEngine : AbstractCalculationEngine;

calcStackSize

The stack size for calculating cells recursively. Default value is 200.

calcStackSize : number;

Remarks

When there are large amount of cells need to be calculated recursively in the dependency tree, StackOverflowException may be caused in the calculation process. If so, user should specify smaller value for this property. For such situation, user should determine the proper value for this property according to the actual formulas and data. However, too small value may cause performance degradation for the formula calculation and value less than 2 will make it impossible to calculate formula which depends on another one. So if the specified value is less than 2, it will be reset to 2.

precisionStrategy

Specifies the strategy for processing precision of calculation.

precisionStrategy : CalculationPrecisionStrategy;

linkedDataSources

Specifies the data sources for external links used in formulas.

linkedDataSources : Workbook[];

Remarks

Like Workbook.UpdateLinkedDataSource(Workbook[]), here you may specify data sources for external links used in formulas to be calculated, especially those used in INDIRECT function. For those external links used in INDIRECT function, they are not taken as part of the external links of the workbook and cannot be updated by Workbook.UpdateLinkedDataSource(Workbook[]). The match of those workbooks with external links is determined by Workbook.FileName and ExternalLink.DataSource. So please make sure Workbook.FileName has been specified with the proper value(generally it should be same with corresponding ExternalLink.DataSource) for every workbook so they can be linked as expected.

characterEncoding

Specifies the encoding used for encoding/decoding characters when calculating formulas. For functions such as CHAR, CODE, the calculated result depends on the region settings and default charset of the environment. With this property user can specify the proper encoding used for those function to get the expected result.

characterEncoding : EncodingType;
