Functions ¶
func AddDialectMappings ¶
func AddDialectMappings(mappings flux.DialectMappings) error
AddDialectMappings adds the influxql specific dialect mappings.
func NewMultiResultEncoder ¶
func NewMultiResultEncoder(c ResultEncoderConfig) flux.MultiResultEncoder
Types ¶
type Dialect ¶
type Dialect struct {
ResultEncoderConfig
}
Dialect describes the output format of queries in CSV.
func DefaultDialect ¶
func DefaultDialect() *Dialect
func (Dialect) DialectType ¶
func (d Dialect) DialectType() flux.DialectType
func (Dialect) Encoder ¶
func (d Dialect) Encoder() flux.MultiResultEncoder
func (Dialect) SetHeaders ¶
func (d Dialect) SetHeaders(w http.ResponseWriter)
type MultiResultDecoder ¶
type MultiResultDecoder struct {
// contains filtered or unexported fields
}
MultiResultDecoder reads multiple results from a single csv file. Results are delimited by an empty line.
func NewMultiResultDecoder ¶
func NewMultiResultDecoder(c ResultDecoderConfig) *MultiResultDecoder
NewMultiResultDecoder creates a new MultiResultDecoder.
func (*MultiResultDecoder) Decode ¶
func (d *MultiResultDecoder) Decode(r io.ReadCloser) (flux.ResultIterator, error)
type ResultDecoder ¶
type ResultDecoder struct {
// contains filtered or unexported fields
}
ResultDecoder decodes a csv representation of a result.
func NewResultDecoder ¶
func NewResultDecoder(c ResultDecoderConfig) *ResultDecoder
NewResultDecoder creates a new ResultDecoder.
type ResultDecoderConfig ¶
type ResultDecoderConfig struct {
// NoHeader indicates that the CSV data will not have a header row.
NoHeader bool
// MaxBufferCount is the maximum number of rows that will be buffered when decoding.
// If 0, then a value of 1000 will be used.
MaxBufferCount int
// Allocator is the memory allocator that will be used during decoding.
// The default is to use an unlimited allocator when this is not set.
Allocator *memory.Allocator
}
ResultDecoderConfig are options that can be specified on the ResultDecoder.
type ResultEncoder ¶
type ResultEncoder struct {
// contains filtered or unexported fields
}
func NewResultEncoder ¶
func NewResultEncoder(c ResultEncoderConfig) *ResultEncoder
NewResultEncoder creates a new encoder with the provided configuration.
func (*ResultEncoder) EncodeError ¶
func (e *ResultEncoder) EncodeError(w io.Writer, err error) error
type ResultEncoderConfig ¶
type ResultEncoderConfig struct {
// Annotations is a list of annotations to include.
Annotations []string
// NoHeader indicates whether a header row should be added.
NoHeader bool
// Delimiter is the character to delimite columns.
// It must not be \r, \n, or the Unicode replacement character (0xFFFD).
Delimiter rune
}
ResultEncoderConfig are options that can be specified on the ResultEncoder.
func DefaultEncoderConfig ¶
func DefaultEncoderConfig() ResultEncoderConfig
func (ResultEncoderConfig) MarshalJSON ¶
func (c ResultEncoderConfig) MarshalJSON() ([]byte, error)
func (*ResultEncoderConfig) UnmarshalJSON ¶
func (c *ResultEncoderConfig) UnmarshalJSON(b []byte) error
