A field is required unless the field is declared with the optional flag set to true. A field with the optional flag set to false is also required.
An optional field may be present or absent in the in-memory data structure or serialized data.
This plugin adds the possibility to display the structured data of the Data Plugin using templates.
The Java binding provides methods to determine if an optional field is present and a specialized get accessor allows the caller to specify whether the default value or null should be returned when an absent optional field is accessed.
The has field accessor may also be used to determine if an optional field is present. Avro’s approach to declaring an optional field is to use a union type whose values may be null or the desired value type.

The resolver opens each of these files until it finds a file that contains the named schema.com/linkedin/pegasus/generator/examples/4.01 compliant. This is because the contents of this string will appear as Javadocs in the generated Java ‘data template’ classes later.Here are a few examples: Differentiate Pegasus supports optional fields implicitly through the “optional” flag in the field definition.---- datatemplateentry member ---- template : tpl_member firstname : Christoph lastname : Clausen type : Ph D Student active : yes phone : 123-987654 email_mail : [email protected]_img : pics:addr : GAP-Optique \ Rue de l' Ecole de Medecine 20 \ CH-1211 Geneve 4 ----.There is the magic “Any” filter which permits to filter with all data displayed columns. When the form is submitted, only those data entries are displayed, where the column selected in the dropdown box contains the text in the text field.Additionally, this plugin offers a custom search form, pagination and result caching.
