Package com.zendesk.maxwell.schema.columndef

Class ColumnDef

java.lang.Object

com.zendesk.maxwell.schema.columndef.ColumnDef

All Implemented Interfaces:

Cloneable

Direct Known Subclasses:

BigIntColumnDef, BitColumnDef, ColumnDefWithLength, DateColumnDef, DecimalColumnDef, EnumeratedColumnDef, FloatColumnDef, GeometryColumnDef, IntColumnDef, JsonColumnDef, StringColumnDef, YearColumnDef

public abstract class ColumnDef
extends Object
implements Cloneable

This class is immutable, all subclasses must be immutable and implement equals and hashCode and call this class's respective methods if the subclass has any member variables. Failure to do so will lead difficult to debug errors as these class instances are interned. Subclasses may use cloneSelfAndSet(java.util.function.Consumer<T>) to follow clone/modify/intern pattern for maintaining interface immutability.
