Method Detail

getExpression1

public Expression getExpression1()

Description copied from interface: BinaryTemporalOperator

Returns the first of the two expressions to be compared by this operator.

Specified by:

getExpression1 in interface BinaryTemporalOperator

getExpression2

public Expression getExpression2()

Description copied from interface: BinaryTemporalOperator

Returns the second of the two expressions to be compared by this operator.

Specified by:

getExpression2 in interface BinaryTemporalOperator

getMatchAction

public MultiValuedFilter.MatchAction getMatchAction()

Description copied from interface: MultiValuedFilter

* Flag Controlling MatchAction property When one or more of the operands evaluates to multiple values rather than a single value, which action should be taken? If there are n values for the left operand and m values for the right operand, there are n * m possible combinations that can be compared,

ANY - if any of the possible combinations match, the result is true (aggregated OR) ALL - only if all of the possible combinations match, the result is true (aggregated AND) ONE - only if exactly one of the possible combinations match, the result is true (aggregated XOR)

Specified by:

getMatchAction in interface MultiValuedFilter

Returns:

MatchAction flag

evaluate

public boolean evaluate(Object object)

Description copied from interface: Filter

Give an object, this method determines if the test(s) represented by this filter object are passed.

This ability is used to allow Queries against both Features and and non spatial data (such as Record) and to express constraints on permissable data values.

Specified by:

evaluate in interface Filter

Returns:

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

toInstant

protected Instant toInstant(Object object,
                            Expression e)

toPeriod

protected Period toPeriod(Object object,
                          Expression e)

toTemporal

protected TemporalPrimitive toTemporal(Object object,
                                       Expression e)

doEvaluate

protected abstract boolean doEvaluate(RelativePosition pos)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Return this filter as a string.

Overrides:

toString in class Object

Returns:

String representation of this temporal filter.
