Types ¶
type ArithmeticLessThanZeroParserError ¶ added in v1.0.0
type ArithmeticLessThanZeroParserError struct {
// contains filtered or unexported fields
}
ArithmeticLessThanZeroParserError - error thrown when parser found integer value that shouldn't be less than 0, but it is
func (*ArithmeticLessThanZeroParserError) Error ¶ added in v1.0.0
func (m *ArithmeticLessThanZeroParserError) Error() string
type IllegalPeriodInIdentParserError ¶ added in v1.0.0
type IllegalPeriodInIdentParserError struct {
// contains filtered or unexported fields
}
IllegalPeriodInIdentParserError - error thrown when parser found period in ident when parsing create command
func (*IllegalPeriodInIdentParserError) Error ¶ added in v1.0.0
func (m *IllegalPeriodInIdentParserError) Error() string
type LogicalExpressionParsingError ¶ added in v1.0.0
type LogicalExpressionParsingError struct {
// contains filtered or unexported fields
}
LogicalExpressionParsingError - error thrown when logical expression inside WHERE statement couldn't be parsed correctly
func (*LogicalExpressionParsingError) Error ¶ added in v1.0.0
func (m *LogicalExpressionParsingError) Error() string
type NoApostropheOnLeftParserError ¶ added in v1.0.0
type NoApostropheOnLeftParserError struct {
// contains filtered or unexported fields
}
NoApostropheOnLeftParserError - error thrown when parser found no apostrophe on left of ident
func (*NoApostropheOnLeftParserError) Error ¶ added in v1.0.0
func (m *NoApostropheOnLeftParserError) Error() string
type NoApostropheOnRightParserError ¶ added in v1.0.0
type NoApostropheOnRightParserError struct {
// contains filtered or unexported fields
}
NoApostropheOnRightParserError - error thrown when parser found no apostrophe on right of ident
func (*NoApostropheOnRightParserError) Error ¶ added in v1.0.0
func (m *NoApostropheOnRightParserError) Error() string
type NoPredecessorParserError ¶ added in v1.0.0
type NoPredecessorParserError struct {
// contains filtered or unexported fields
}
NoPredecessorParserError - error thrown when parser found integer value that shouldn't be less than 0, but it is
func (*NoPredecessorParserError) Error ¶ added in v1.0.0
func (m *NoPredecessorParserError) Error() string
type Parser ¶
type Parser struct {
// contains filtered or unexported fields
}
Parser - Contain token that is currently analyzed by parser and the next one. Lexer is used to tokenize the client text input.
func (*Parser) ParseSequence ¶
ParseSequence - Return ast.Sequence (sequence of commands) created from client input after tokenization
Parse tokens returned by lexer to structures defines in ast package, and it's responsible for syntax validation.
type SyntaxCommandExpectedError ¶ added in v1.0.0
type SyntaxCommandExpectedError struct {
// contains filtered or unexported fields
}
SyntaxCommandExpectedError - error thrown when there was command that logically should only appear after certain different command, but it wasn't found
func (*SyntaxCommandExpectedError) Error ¶ added in v1.0.0
func (m *SyntaxCommandExpectedError) Error() string
type SyntaxError ¶ added in v1.0.0
type SyntaxError struct {
// contains filtered or unexported fields
}
SyntaxError - error thrown when parser was expecting different token from lexer
func (*SyntaxError) Error ¶ added in v1.0.0
func (m *SyntaxError) Error() string
type SyntaxInvalidCommandError ¶ added in v1.0.0
type SyntaxInvalidCommandError struct {
// contains filtered or unexported fields
}
SyntaxInvalidCommandError - error thrown when invalid (non-existing) type of command has been found
func (*SyntaxInvalidCommandError) Error ¶ added in v1.0.0
func (m *SyntaxInvalidCommandError) Error() string
