org.eclipse.birt.report.model.api.validators.MasterPageMultiColumnValidator

public class MasterPageMultiColumnValidator extends org.eclipse.birt.report.model.validators.AbstractElementValidator
Validates the multiple columns and content width should be consistent. This validator should be performed after MasterPageTypeValidator and MasterPageSizeValidator.

Rule

The rule is that the width occupied by column spacing is less than the content width.

column spacing width = (COLUMNS_PROP - 1) * COLUMN_SPACING_PROP

content width = WIDTH_PROP - LEFT_MARGIN_PROP - RIGHT_MARGIN_PROP

column spacing width < content width

Applicability

This validator is only applied to GraphicMasterPage.
