FunctionsFilter Class

In This Topic

This class represents filter of Function and derived from it classes. The FunctionsFilter can be accessed as a property of a Page object or can be used as a parameter for DMObjectsFinder. Setting more than one criterion of matching the filter (for \example Page that the matching function must be placed on, and the matching functions category, causes that returned functions must match both conditions.

Syntax

public class FunctionsFilter : PlacementsFilter

public ref class FunctionsFilter : public PlacementsFilter

Example

Project proj;//a valid project
Page p;//a valid page object

p.Filter.Category = Function.Enums.Category.MOTOR;

//now we have all functions having category 'MOTOR' placed on page p
Function[] functions = p.Functions;

//other way to do the same:
FunctionFilter ff = new FunctionFilter();
ff.Category = Function.Enums.Category.MOTOR;
ff.Page = p;
DMObjectsFinder objFinder = DMObjectsFinder(proj);

//now we have all functions having category 'MOTOR' placed on page p
functions = objFinder.GetFunctions(ff);

The following example shows how to filter by user-defined properties

MultiLangString mlsTestValue = new MultiLangString();
mlsTestValue.AddString(ISOCode.Language.L_de_DE, "Test043c");
string strPropertyIdentyfingName = "Page.Test043c";
UserDefinedPropertyDefinition oUDPD = UserDefinedPropertyDefinition.Create(m_oProject, strPropertyIdentyfingName, UserDefinedPropertyDefinition.Enums.ClientType.Page);

//set test property
Page oPage = m_oProject.Pages[0];
oPage.Properties[strPropertyIdentyfingName] = mlsTestValue;

//search page with property value
DMObjectsFinder oFinder = new DMObjectsFinder(m_oProject);
PagesFilter oPagesFilter = new PagesFilter();
PagePropertyList oPagePropertyList = new PagePropertyList();
AnyPropertyId oAnyPropertyId = new AnyPropertyId(m_oProject, strPropertyIdentyfingName);
oPagePropertyList[oAnyPropertyId] = mlsTestValue;
oPagesFilter.SetFilteredPropertyList(oPagePropertyList);
Page[] arrPages1 = oFinder.GetPages(oPagesFilter);

Public Properties

	Name	Description
	Category	Gets/Sets the Category that was set to this filter.
	ExactNameMatching	Gets/Sets if the filtered function, when is filtered by name, should be matched exactly, it means that if searched name is only its name' prefix, it is not matching to the filter. Dafault this property is `false`.
	IsPlaced	Gets/Sets if the filtered function should be placed (i.e. should be located on a valid page).
	Name	Gets/Sets the name that was set to this filter.
	Page	Overridden. Sets the Page that StorableObjects matching the filter must be placed on.

Public Methods

	Name	Description
	Dispose()	Destructor for deterministic finalization of FunctionFilter object. (Inherited from Eplan.EplApi.DataModel.AbstractDMObjectFilter)
	ResetFilter	Overridden. Resets the filter. Filter matches all Functions then.
	SetFilteredPropertyList	Overloaded. Sets the FunctionBasePropertyList that Functions matching the filter must have.
	SetIdentifyingPropertyList	Overloaded. Sets the FunctionBasePropertyList that identifies the matching Functions.
