Types ¶
type CaseChangingStream ¶
type CaseChangingStream struct {
antlr.CharStream
// contains filtered or unexported fields
}
CaseChangingStream wraps an existing CharStream, but upper cases, or lower cases the input before it is tokenized.
func (*CaseChangingStream) LA ¶
func (is *CaseChangingStream) LA(offset int) int
LA gets the value of the symbol at offset from the current position from the underlying CharStream and converts it to either upper case or lower case.
type Parser ¶
type Parser struct {
// contains filtered or unexported fields
}
func New ¶
func New(query string, tr ...TokenStreamTransformer) *Parser
func (*Parser) AddErrorListener ¶
func (p *Parser) AddErrorListener(listener antlr.ErrorListener)
func (*Parser) Expression ¶
func (p *Parser) Expression() fql.IExpressionContext
Expression parses a standalone expression.
func (*Parser) GetLiteralNames ¶
func (*Parser) Program ¶
func (p *Parser) Program() *fql.ProgramContext
Program parses and returns the source program, caching the parse tree so syntax diagnostics can be inspected before visitors consume it.
func (*Parser) RemoveErrorListeners ¶
func (p *Parser) RemoveErrorListeners()
func (*Parser) Visit ¶
func (p *Parser) Visit(visitor fql.FqlParserVisitor) interface{}
func (*Parser) Walk ¶
func (p *Parser) Walk(listener fql.FqlParserListener)
type TokenStreamTransformer ¶
type TokenStreamTransformer func(antlr.TokenStream) antlr.TokenStream
