And

And(Collection<? extends Filter<? super R>> op)

Creates a new operator for the given operands.

And

And(Filter<? super R> operand1,
 Filter<? super R> operand2)

Creates a new operator for the two given operands.

Method Details

createSameType

protected LogicalFilter<R> createSameType(Collection<? extends Filter<? super R>> op)

Creates a new logical operator of the same kind than this operator.

Specified by:

createSameType in class LogicalFilter<R>

Parameters:

op - operands of the new operator.

Returns:

the new operator.

getOperatorType

public LogicalOperatorName getOperatorType()

Identification of the operation.

Returns:

the nature of this operator.

symbol

protected char symbol()

Symbol of the operation.

Overrides:

symbol in class Node

Returns:

the mathematical symbol, or 0 if none.

test

public boolean test(R object)

Executes the logical operation.

Parameters:

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

Returns:

true if the test(s) are passed for the provided object.

optimize

public Filter<? super R> optimize(Optimization optimization)

Tries to optimize this filter.

Parameters:

optimization - the simplifications or optimizations to apply on this filter.

Returns:

the simplified or optimized filter, or this if no optimization has been applied.
