Class BuildVisitor

java.lang.Object
  com.samskivert.jdbc.depot.BuildVisitor

All Implemented Interfaces:

ExpressionVisitor

Direct Known Subclasses:

MySQLBuilder.MSBuildVisitor, PostgreSQLBuilder.PGBuildVisitor

public abstract class BuildVisitor
extends Object
implements ExpressionVisitor

Implements the base functionality of the SQL-building pass of SQLBuilder. Dialectal subclasses of this should be created and returned from SQLBuilder.getBuildVisitor(). This class is intimately paired with {#link BindVisitor}.

Field Summary

protected StringBuilder	_builder A StringBuilder to hold the constructed SQL.
protected Map<Class<? extends PersistentRecord>,Map<String,FieldDefinition>>	_definitions A mapping of field overrides per persistent record.
protected boolean	_enableAliasing
protected boolean	_enableOverrides
protected boolean	_innerClause A flag that's set to true for inner SELECT's
protected DepotTypes	_types
