Constructor & Destructor Documentation

◆ KDbToken() [1/3]

KDbToken::KDbToken ( )
inline

Creates an invalid token.

Todo
add KDbToken(const QByteArray &name)

Definition at line 42 of file KDbToken.h.

◆ KDbToken() [2/3]

KDbToken::KDbToken ( const KDbToken & other)
inline

Definition at line 44 of file KDbToken.h.

◆ KDbToken() [3/3]

KDbToken::KDbToken ( char charToken)

Creates a single-character token Only characters that belong to the grammar are accepted: ';' ',' '.

' '>' '<' '=' '+' '-' '&' '|' '/' '*' '' '~' '#' ':' '(' ')' Invalid KDbToken is created for character that is not accepted.

Definition at line 33 of file KDbToken.cpp.

Member Function Documentation

◆ allTokens()

QList< KDbToken > KDbToken::allTokens ( )
static

Definition at line 122 of file KDbToken.cpp.

◆ isValid()

bool KDbToken::isValid ( ) const
inline
Returns
true if this token is valid

Definition at line 53 of file KDbToken.h.

◆ name()

QString KDbToken::name ( ) const
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.

Definition at line 38 of file KDbToken.cpp.

◆ operator!=() [1/2]

bool KDbToken::operator!= ( char charToken) const
inline
Returns
true if this token is not equal to other token

Definition at line 97 of file KDbToken.h.

◆ operator!=() [2/2]

bool KDbToken::operator!= ( KDbToken other) const
inline
Returns
true if this token is not equal to other token

Definition at line 91 of file KDbToken.h.

◆ operator=()

void KDbToken::operator= ( char charToken)
inline

Assigns a token.

Definition at line 100 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
inline
Returns
true if this token is equal to other token

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]

QString KDbToken::toString ( const KDbDriver * driver = nullptr) const
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]

QString KDbToken::toString ( KDbToken token,
const KDbDriver * driver = nullptr )
static

Like toString(const KDbDriver *driver)

Definition at line 92 of file KDbToken.cpp.

◆ value()

int KDbToken::value ( ) const
inline
Returns
numeric value of this token

Definition at line 85 of file KDbToken.h.
