Method Details

getVendor

public EDbVendor getVendor()

Description copied from interface: SqlParser

Get the database vendor this parser handles.

Specified by:

getVendor in interface SqlParser

Returns:

the database vendor (e.g., dbvoracle, dbvmysql)

parse

public SqlParseResult parse(ParserContext context)

Description copied from interface: SqlParser

Parse SQL from the given context.

This method performs full parsing including:

• Tokenization (lexical analysis)
• Syntax analysis (building parse tree)
• Semantic analysis (resolving references)

All inputs come from the context parameter, all outputs go to the result. This ensures clean separation of concerns and thread-safety.

Specified by:

parse in interface SqlParser

Parameters:

context - immutable context containing all parser inputs (SQL text, options, callbacks, etc.)

Returns:

immutable result containing all parser outputs (statements, tokens, errors, etc.)

tokenize

public SqlParseResult tokenize(ParserContext context)

Description copied from interface: SqlParser

Tokenize SQL without parsing or statement extraction.

This method performs only tokenization (lexical analysis):

• Tokenization (lexical analysis)

The result contains tokens but NO statements. Use this when you only need the token stream (e.g., for syntax highlighting, token analysis).

For statement boundaries without full parsing, use SqlParser.getrawsqlstatements(ParserContext).

Specified by:

tokenize in interface SqlParser

Parameters:

context - immutable context containing all parser inputs

Returns:

immutable result containing tokens only (no statements)

toString

public String toString()

Overrides:

toString in class Object
