Interface BeanBlockSource

All Known Implementing Classes:
BeanBlockSourceImpl

A source of Blocks used to display the properties of a bean (used by the Grid component), or to edit the properties of a bean (used by the BeanEditForm component). Contributions to this service (a configuration of BeanBlockContributions) define what properties may be editted. Blocks are accessed in terms of a data type a string that identifies the type of data to be editted, such as "string", "date", "boolean", etc. Tapestry contributes a number of default data types and corresponding edit and display blocks. The BeanBlockOverrideSource service allows these to be overridden.
