public abstract List<FunctionOption> options()

aggregationPhase

public abstract Expression.AggregationPhase aggregationPhase()

partitionBy

public abstract List<Expression> partitionBy()

sort

public abstract List<Expression.SortField> sort()

getType

public Type getType()

Specified by:

getType in interface Expression

invocation

public abstract Expression.AggregationInvocation invocation()

check

@Check
protected void check()

Validates that variadic arguments satisfy the parameter consistency requirement. When CONSISTENT, all variadic arguments must have the same type (ignoring nullability). When INCONSISTENT, arguments can have different types.

builder

accept

public <R,
C extends VisitationContext,
E extends Throwable>
R accept(ExpressionVisitor<R,C,E> visitor,
 C context)
  throws E

Specified by:

accept in interface Expression

Throws:

E extends Throwable
