Overview

Package spanfiltering provides primitives for transpiling AIP filter expressions to Spanner SQL expressions.

Index

• func TranspileFilter(filter filtering.Filter) (spansql.BoolExpr, map[string]interface{}, error)
• type Transpiler
  • func (t *Transpiler) Init(filter filtering.Filter)
  • func (t *Transpiler) Transpile() (spansql.BoolExpr, map[string]interface{}, error)

Functions

func TranspileFilter

func TranspileFilter(filter filtering.Filter) (spansql.BoolExpr, map[string]interface{}, error)

TranspileFilter transpiles a parsed AIP filter expression to a spansql.BoolExpr, and parameters used in the expression. The parameter map is nil if the expression does not contain any parameters.

Types

type Transpiler

type Transpiler struct {
	// contains filtered or unexported fields
}

func (*Transpiler) Init

func (t *Transpiler) Init(filter filtering.Filter)

func (*Transpiler) Transpile

func (t *Transpiler) Transpile() (spansql.BoolExpr, map[string]interface{}, error)
