Constructor Details

BinaryComparison

protected BinaryComparison(Source source,
 Expression left,
 Expression right,
 BinaryComparisonOperation operation,
 ZoneId zoneId)

Method Details

zoneId

public ZoneId zoneId()

resolveInputType

protected Expression.TypeResolution resolveInputType(Expression e,
 TypeResolutions.ParamOrdinal paramOrdinal)

Specified by:

resolveInputType in class BinaryOperator<Object,Object,Boolean,BinaryComparisonOperation>

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.

Specified by:

dataType in class Expression

compare

public static Integer compare(Object left,
 Object right)

reverse

public abstract BinaryComparison reverse()

Reverses the direction of this comparison on the comparison axis. Some operations like Greater/LessThan/OrEqual will behave as if the operands of a numerical comparison get multiplied with a negative number. Others like Not/Equal can be immutable to this operation.
