Method Detail

getExpression

public Expression getExpression()

Description copied from interface: PropertyIsBetween

Returns the expression to be compared by this operator.

Specified by:

getExpression in interface PropertyIsBetween

setExpression

public void setExpression(Expression expression)

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

Overrides:

getMatchAction in class BinaryComparisonAbstract

Returns:

MatchAction flag

evaluate

public boolean evaluate(Object feature)

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

evaluateInternal

public boolean evaluateInternal(Object value,
                                Object lower,
                                Object upper)

accept

public Object accept(FilterVisitor visitor,
                     Object extraData)

Description copied from class: CompareFilterImpl

Used by FilterVisitors to perform some action on this filter instance. Typicaly used by Filter decoders, but may also be used by any thing which needs infomration from filter structure. Implementations should always call: visitor.visit(this); It is importatant that this is not left to a parent class unless the parents API is identical.

Specified by:

accept in interface Filter

Specified by:

accept in class CompareFilterImpl

Parameters:

visitor - The visitor which requires access to this filter, the method must call visitor.visit(this);

getLowerBoundary

public Expression getLowerBoundary()

Description copied from interface: PropertyIsBetween

Returns the lower bounds (inclusive) an an expression.

Specified by:

getLowerBoundary in interface PropertyIsBetween

setLowerBoundary

public void setLowerBoundary(Expression lowerBoundary)

getUpperBoundary

public Expression getUpperBoundary()

Description copied from interface: PropertyIsBetween

Returns the upper bounds (inclusive) as an expression.

Specified by:

getUpperBoundary in interface PropertyIsBetween

setUpperBoundary

public void setUpperBoundary(Expression upperBoundary)

toString

public String toString()

Description copied from class: CompareFilterImpl

Returns a string representation of this filter.

Overrides:

toString in class CompareFilterImpl

Returns:

String representation of the compare filter.

hashCode

public int hashCode()

Description copied from class: CompareFilterImpl

Override of hashCode method.

Overrides:

hashCode in class CompareFilterImpl

Returns:

a code to hash this object by.

equals

public boolean equals(Object obj)

Description copied from class: CompareFilterImpl

Compares this filter to the specified object. Returns true if the passed in object is the same as this filter. Checks to make sure the filter types are the same as well as both of the values.

Overrides:

equals in class CompareFilterImpl

Parameters:

obj - - the object to compare this CompareFilter against.

Returns:

true if specified object is equal to this filter; false otherwise.
