Class ParserContext

Object

gudusoft.gsqlparser.parser.ParserContext

public final class ParserContext
extends Object

Immutable context carrying all parser inputs and settings.

This value object encapsulates all inputs required for SQL parsing, providing clean separation between input configuration and parser implementation. Once built, a ParserContext instance cannot be modified (immutable).

Design Pattern: Value Object + Builder

• Immutable: Thread-safe, no defensive copying needed
• Builder: Flexible construction with optional parameters
• Clean boundaries: Input/Output separation

Usage Example:

 ParserContext context = new ParserContext.Builder(EDbVendor.dbvoracle)
     .sqlText("SELECT * FROM employees WHERE salary > 50000")
     .enablePartialParsing(true)
     .metaDatabase(myMetaDatabase)
     .build();
 

Since:

3.2.0.0

getOceanBaseTenantMode

public EOBTenantMode getOceanBaseTenantMode()

Get the OceanBase tenant compatibility mode mirrored from the owning TGSqlParser. Always non-null. Meaningful only when getVendor() is dbvoceanbase; otherwise defaults to EOBTenantMode.MYSQL and is ignored by other vendor parsers.

Returns:

the OceanBase tenant mode (never null)
