Method Details

getWriteableName

public String getWriteableName()

Specified by:

getWriteableName in interface NamedWriteable

factories

protected Map<DataType,AbstractConvertFunction.BuildFactory> factories()

Description copied from class: AbstractConvertFunction

A map from input type to ExpressionEvaluator ctor. Usually implemented like:

     private static final Map<DataType, BuildFactory> EVALUATORS = Map.ofEntries(
         Map.entry(BOOLEAN, (field, source) -> field),
         Map.entry(KEYWORD, ToBooleanFromStringEvaluator.Factory::new),
         ...
     );

     @Override
     protected Map<DataType, BuildFactory> factories() {
         return EVALUATORS;
     }
 

Specified by:

factories in class AbstractConvertFunction

dataType

public DataType dataType()

Description copied from class: Expression

The DataType returned by executing the tree rooted at this expression. If Expression.typeResolved() returns an error then the behavior of this method is undefined. It may return a valid type. Or it may throw an exception. Or it may return a totally nonsensical type.

Overrides:

dataType in class UnaryScalarFunction

replaceChildren

public Expression replaceChildren(List<Expression> newChildren)

Specified by:

replaceChildren in class Node<Expression>

info

protected NodeInfo<? extends Expression> info()

Description copied from class: Node

Normally, you want to use one of the static create methods to implement this.

For QueryPlans, it is very important that the properties contain all of the expressions and references relevant to this node, and that all the properties are used in the provided constructor; otherwise query plan transformations like QueryPlan#transformExpressionsOnly(Function) will not have an effect.

Specified by:

info in class Node<Expression>

configuration

public Configuration configuration()

Specified by:

configuration in interface ConfigurationAware

withConfiguration

public ToDateRange withConfiguration(Configuration configuration)

Specified by:

withConfiguration in interface ConfigurationAware

hashCode

public int hashCode()

Overrides:

hashCode in class Function

equals

public boolean equals(Object obj)

Overrides:

equals in class Function
