Method Details

getOperatorType

public LogicalOperatorName getOperatorType()

Identification of the operation.

Specified by:

getOperatorType in interface Filter<R>

getOperatorType in interface LogicalOperator<R>

Returns:

the nature of this operator.

symbol

protected char symbol()

Specified by:

test in interface Filter<R>

Specified by:

test in interface Predicate<R>

Parameters:

object - the object (often a Feature instance) to evaluate.
