Creates a single-character token Only characters that belong to the grammar are accepted: ';' ',' '.
' '>' '<' '=' '+' '-' '&' '|' '/' '*' '' '~' '#' ':' '(' ')' Invalid KDbToken is created for character that is not accepted.

◆ allTokens()
◆ isValid()
bool KDbToken::isValid |
( |
| ) |
const |
|
inline |
- Returns
- true if this token is valid
Definition at line 53 of file KDbToken.h.
◆ name()
- Returns
- name of this token Useful for debugging. For example "NOT_EQUAL" string is returned for the NOT_EQUAL token. A single character is returned for printable single-character tokens. A number is returned for non-printable single-character. "<INVALID_TOKEN>" is returned for an invalid string.

- Returns
- true if this token is not equal to other token
Definition at line 97 of file KDbToken.h.

KDbToken | other | ) |
const |

- Returns
- true if this token is not equal to other token
Definition at line 91 of file KDbToken.h.

◆ operator==() [1/2]
bool KDbToken::operator== |
( |
char | charToken | ) |
const |
|
inline |
- Returns
- true if this token is equal to other token
Definition at line 94 of file KDbToken.h.
◆ operator==() [2/2]
bool KDbToken::operator== |
( |
KDbToken | other | ) |
const |

Definition at line 88 of file KDbToken.h.
◆ toChar()
char KDbToken::toChar |
( |
| ) |
const |
|
inline |
- Returns
- character equivalent of this token Only character-based tokens are supported this way (toInt() <= maxCharTokenValue). For unsupported tokens
nullptr
is returned.
Definition at line 82 of file KDbToken.h.
◆ toString() [1/2]
- Returns
- string interpretation of this token (as visibe to the user) For example "<>" is returned for the NOT_EQUAL token. Empty string is returned for an invalid string The result may depend on the optional driver parameter. If driver is
nullptr
, representation for portable KDbSQL dialect is returned.
Definition at line 54 of file KDbToken.cpp.
◆ toString() [2/2]
Like toString(const KDbDriver *driver)

- Returns
- numeric value of this token

Custom tokens are not used in parser but used as an extension in expression classes.
