ContentModifier

Based on ContentModifier interface.

Content modifiers are used to modify how instances of specified ECClasses are displayed in content which is produced using content rules. They do not produce any content by themselves.

Attributes

Name	Required?	Type	Default	Meaning
Picking attributes
`class`	No	`SingleSchemaClassSpecification`	``	Specification of ECClass whose content displayed should be modified. The modifier is applied to all ECClasses if this attribute is not specified.
`requiredSchemas`	No	`RequiredSchemaSpecification[]`	`[]`	Specifications that define schema requirements for the rule to take effect.
Content Modifiers
`relatedProperties`	No	`RelatedPropertiesSpecification[]`	`[]`	Specifications of related properties which are included in the generated content. See this page for more details
`calculatedProperties`	No	`CalculatedPropertiesSpecification[]`	`[]`	Specifications of calculated properties whose values are generated using provided ECExpressions. See this page for more details
`propertyCategories`	No	`PropertyCategorySpecification[]`	`[]`	Specifications for custom categories. Simply defining the categories does nothing - they have to be referenced from `PropertySpecification` defined in `propertyOverrides` by `id`. See this page for more details
`propertyOverrides`	No	`PropertySpecification[]`	`[]`	Specifications for various property overrides. See this page for more details
