Commands¶

Commands is Building block of BasisCore language and Present in XML notation format mixed with HTML. All basisCore commands inherit from CommandBase Class. For list of BasisCore built-in commands in Built-in Commands

Simple BasisCore print command¶

<basis  core="print" datamembername="db.user-info">
   <face>
      hello world!
   </face>
</basis>

Some BasisCore Command is void element like Cookie Command, for Example:

BasisCore cookie void command¶

<basis core="cookie" name="rkey" value="[##db.user-info.rkey##]" max-age="2021" />

Remarks¶

All command internally use a instance of Context for perform processing. For example some command like DbSource add data source to this object that server with other command. Some command like Print Command use this Context object for retrieve needed data source for perform rendering process. Other type of commands like Group Command or Export Command change pipeline of generating result.
