Example 3 with FieldMetaData

use of org.jaffa.metadata.FieldMetaData in project jaffa-framework by jaffa-projects.

the class StringHelper method formatDescription.

/**
 * This method is invoked in cases where 'description' field is appended to a 'code' field.
 * This method formats the input dexcriptionField based on the passed layout.
 * The layout can be passed directly or can be determined from the parameters domainClassWithPackage and domainField, through the appropriate FieldMetaData object.
 * It then truncates the formatted String to the input limit. If the String is truncated, then the truncateIndicator will be appended.
 * No truncation will be performed if the limit <= 0
 * Finally the String will be packaged between the beginMarker and endMarker.
 * If the toHtml flag is true, then the result will made HTML safe.
 * @param field The description of the field.
 * @param layout The layout, if any to be used for formatting
 * @param domainClassWithPackage The domainClass to determine the FieldMetaData object, to get a handle on the layout.
 * @param domainField The domainField to determine the FieldMetaData object, to get a handle on the layout.
 * @param toHtml if true, then the output will be converted to HTML.
 * @param beginMarker The marker at the start of the output. Default is ' ('
 * @param endMarker The marker at the end of the output. Default is ')'
 * @param limit The limit for the formatted decription. Default is 25.
 * @param truncateIndicator The string to append tot he formatted description, if exceeds the limit and is truncated.
 * @return the formatted string packed between the markers. An empty String will be returned, in case the input field is null.
