Uses of CommandHandler in dev.frostlake.executor.commands

Classes in dev.frostlake.executor.commands that implement CommandHandler

Modifier and Type	Class	Description
class	AlterCommandHandler	Handles ALTER <object-type> … statements for DATABASE / SCHEMA / MASKING & ROW ACCESS POLICY / TABLE / VIEW / STREAM / TASK / PIPE / WAREHOUSE / STAGE / USER / ROLE / SESSION / TAG, extracted verbatim from SQLCommandVisitor.visitAlterStatement(dev.frostlake.parser.FrostlakeParser.AlterStatementContext).
class	BeginEndBlockHandler	Handles Snowflake Scripting BEGIN … [EXCEPTION …] END blocks, extracted verbatim from SQLCommandVisitor.visitBeginEndBlock(dev.frostlake.parser.FrostlakeParser.BeginEndBlockContext) together with its cohesive exception-handling helpers (bindHandlerErrorVariables, shouldHandleException, matchesSnowflakeException — each used only by this path).
class	ColumnDefinitionParser	Parses column / data-type / constraint / default-value grammar into metastore models — extracted from DDLCommandHandler (CREATE TABLE, CREATE FUNCTION/PROCEDURE parameters, DROP FUNCTION arg types, ALTER) so those handlers share one parser.
class	CommentCommandHandler	Handles COMMENT ON <object-type> … statements, extracted verbatim from SQLCommandVisitor.visitCommentStatement(dev.frostlake.parser.FrostlakeParser.CommentStatementContext).
class	CreateInfrastructureHandler	Handles CREATE for infrastructure objects — TASK, PIPE, SEQUENCE, WAREHOUSE, STAGE — extracted from DDLCommandHandler, which keeps the CREATE dispatch and delegates here.
class	CreateNamespaceHandler	Handles the namespace CREATE shapes — DATABASE and SCHEMA (including CLONE) — extracted from DDLCommandHandler, which keeps the CREATE dispatch and delegates here.
class	CreateRelationalHandler	Handles the SELECT-backed CREATE shapes — VIEW, MATERIALIZED VIEW, and DYNAMIC TABLE — extracted from DDLCommandHandler, which keeps the CREATE dispatch and delegates here.
class	CreateRoutineHandler	Handles CREATE FUNCTION and CREATE PROCEDURE (UDF / stored-procedure creation across SQL/JS/Python/Java/ Scala), extracted from DDLCommandHandler, which keeps the CREATE dispatch and delegates here.
class	CreateSecurityHandler	Handles CREATE for security / governance objects — TAG, MASKING POLICY, ROW ACCESS POLICY, USER, ROLE — extracted from DDLCommandHandler, which keeps the CREATE dispatch and delegates here.
class	CreateTableHandler	Handles CREATE TABLE (plain, CLONE, and CREATE TABLE AS SELECT), extracted from DDLCommandHandler, which keeps the CREATE dispatch and delegates here.
class	DDLCommandHandler	Handler for DDL (Data Definition Language) commands: CREATE, DROP, ALTER, USE, TRUNCATE, COMMENT
class	DMLCommandHandler	Handler for DML (Data Manipulation Language) commands: INSERT, UPDATE, DELETE, MERGE
class	DropCommandHandler	Handles DROP statements (DROP TABLE/VIEW/DATABASE/SCHEMA/STREAM/TASK/SEQUENCE/...), extracted from DDLCommandHandler, which keeps the public dispatch and delegates here.
class	GrantRevokeHandler	Handles GRANT … and REVOKE … statements, extracted verbatim from SQLCommandVisitor.visitGrantStatement(dev.frostlake.parser.FrostlakeParser.GrantStatementContext) and SQLCommandVisitor.visitRevokeStatement(dev.frostlake.parser.FrostlakeParser.RevokeStatementContext).
class	QueryCommandHandler	Handler for Query commands: SELECT statements
class	ShowCommandHandler	Handler for SHOW and DESCRIBE commands: SHOW DATABASES, SHOW SCHEMAS, SHOW TABLES, DESCRIBE TABLE, etc.
