Methods in org.apache.druid.math.expr that return Expr.BindingAnalysis

Modifier and Type	Method	Description
static Expr.BindingAnalysis	Exprs.analyzeBindings(List<Expr> args)	Return a Expr.BindingAnalysis that represents an analysis of all provided args.
Expr.BindingAnalysis	Expr.analyzeInputs()	Examine the usage of IdentifierExpr children of an Expr, constructing a Expr.BindingAnalysis
Expr.BindingAnalysis	ExprMacroTable.BaseMacroFunctionExpr.analyzeInputs()
Expr.BindingAnalysis	LambdaExpr.analyzeInputs()
static Expr.BindingAnalysis	Expr.BindingAnalysis.collect(Collection<Expr.BindingAnalysis> others)	Create an instance by combining a collection of other instances.
static Expr.BindingAnalysis	Expr.BindingAnalysis.collectExprs(Collection<Expr> exprs)	Create an instance by combining a collection of analyses from Expr.analyzeInputs().
protected abstract Expr.BindingAnalysis	ExprMacroTable.BaseMacroFunctionExpr.supplyAnalyzeInputs()	Implemented by subclasses to provide the value for ExprMacroTable.BaseMacroFunctionExpr.analyzeInputs(), which uses a memoized supplier.
protected Expr.BindingAnalysis	ExprMacroTable.BaseScalarMacroFunctionExpr.supplyAnalyzeInputs()
Expr.BindingAnalysis	Expr.BindingAnalysis.withArrayArguments(Set<Expr> arrayArguments)	Add set of arguments as arrayVariables that are *directly* IdentifierExpr, else they are ignored.
Expr.BindingAnalysis	Expr.BindingAnalysis.withArrayInputs(boolean hasArrays)	Copy, setting if an expression has array inputs
Expr.BindingAnalysis	Expr.BindingAnalysis.withArrayOutput(boolean isOutputArray)	Copy, setting if an expression produces an array output
Expr.BindingAnalysis	Expr.BindingAnalysis.withScalarArguments(Set<Expr> scalarArguments)	Add set of arguments as scalarVariables that are *directly* IdentifierExpr, else they are ignored.

Methods in org.apache.druid.math.expr with parameters of type Expr.BindingAnalysis

Modifier and Type	Method	Description
static Expr	Parser.applyUnappliedBindings(Expr expr, Expr.BindingAnalysis bindingAnalysis, List<String> bindingsToApply)	Applies a transformation to an Expr given a list of known (or uknown) multi-value input columns that are used in a scalar manner, walking the Expr tree and lifting array variables into the LambdaExpr of ApplyFunctionExpr and transforming the arguments of FunctionExpr as necessary.
static Expr	Parser.foldUnappliedBindings(Expr expr, Expr.BindingAnalysis bindingAnalysis, List<String> bindingsToApply, String accumulatorId)	Applies a transformation to an Expr given a list of known (or uknown) multi-value input columns that are used in a scalar manner, walking the Expr tree and lifting array variables into the LambdaExpr of ApplyFunctionExpr and transforming the arguments of FunctionExpr as necessary.
static void	Parser.validateExpr(Expr expression, Expr.BindingAnalysis bindingAnalysis)	Validate that an expression uses input bindings in a type consistent manner.

Method parameters in org.apache.druid.math.expr with type arguments of type Expr.BindingAnalysis

Modifier and Type	Method	Description
static Expr.BindingAnalysis	Expr.BindingAnalysis.collect(Collection<Expr.BindingAnalysis> others)	Create an instance by combining a collection of other instances.

Uses of Expr.BindingAnalysis in org.apache.druid.segment.virtual

Methods in org.apache.druid.segment.virtual that return Expr.BindingAnalysis

Modifier and Type	Method	Description
Expr.BindingAnalysis	ExpressionPlan.getAnalysis()	Returns basic analysis of the inputs to an Expr and how they are used

Methods in org.apache.druid.segment.virtual with parameters of type Expr.BindingAnalysis

Modifier and Type	Method	Description
static boolean	ExpressionSelectors.canMapOverDictionary(Expr.BindingAnalysis bindingAnalysis, ColumnCapabilities columnCapabilities)	Returns whether an expression can be applied to unique values of a particular column (like those in a dictionary) rather than being applied to each row individually.
