Classification of a CQL token.

Variants§

§

Keyword

A CQL keyword (SELECT, FROM, WHERE, etc.). Determined by context — words in identifier position (after FROM, after dot, etc.) are Identifier instead.

§

Identifier

An unquoted identifier (table name, column name, keyspace name, etc.).

§

QuotedIdentifier

A double-quoted identifier ("MyTable").

§

StringLiteral

A single-quoted string literal ('hello').

§

DollarStringLiteral

A dollar-quoted string literal ($$body$$).

§

NumberLiteral

A numeric literal (integer or decimal: 42, 3.14, -1).

§

BlobLiteral

A blob literal (0xDEADBEEF).

§

UuidLiteral

A UUID literal (550e8400-e29b-41d4-a716-446655440000).

§

BooleanLiteral

A boolean literal (true, false).

§

Operator

An operator (=, <, >, <=, >=, !=, +, -, etc.).

§

Punctuation

Punctuation (;, ,, (, ), ., *, ?).

§

Whitespace

Whitespace (spaces, tabs, newlines).

§

LineComment

A line comment (-- ...).

§

BlockComment

A block comment (/* ... */), possibly nested.

§

Unknown

Unrecognized character.
