Class ParserContext.Builder

Object
gudusoft.gsqlparser.parser.ParserContext.Builder
Enclosing class:
ParserContext
public static class ParserContext.Builder extends Object
Builder for constructing ParserContext instances.

The Builder pattern provides:

  • Flexible construction with optional parameters
  • Readable, fluent API
  • Default values for optional parameters
  • Immutability of final ParserContext object

Example: 

 ParserContext ctx = new ParserContext.Builder(EDbVendor.dbvoracle)
     .sqlText("SELECT * FROM dual")
     .enablePartialParsing(true)
     .metaDatabase(myMetaDb)
     .build();
