Class ColumnsBuilder

java.lang.Object
  de.twenty11.skysail.common.grids.ColumnsBuilder

public abstract class ColumnsBuilder
extends Object

Subclasses have to implement the configure method, which typically looks something like addColumn("col1").setWidth(100).addColumn("col2")... This class is meant to be used a domain-specific-language style which lets you define a chain of columns and provide specific details to each column. The typical use is to create an anonymous inner class like in this snippet gridData.setColumnsBuilder(new ColumnsBuilder(...) {...});. This use case doesn't have to deal with concurrency issues, so no special care is taken to make this class ThreadSafe.
