public abstract class LogicalOperationFilterImpl
extends AbstractEventFilter
implements LogicalOperationFilter

Is the basis for any LogicalOperationFilter implementation. Contains a set of filters and offers package intern methods to modify this set

Constructor Detail

LogicalOperationFilterImpl

public LogicalOperationFilterImpl(EventFilter... filters)

Creates a filter containing the given filters as operands

Parameters:

filters - to be operands

Method Detail

getOperands

public java.util.Set<EventFilter> getOperands()

Returns a read-only collection containing the filters

Specified by:

getOperands in interface LogicalOperationFilter

clearOperands

protected void clearOperands()

Clears the operands

addOperand

protected void addOperand(EventFilter filter)

Adds an filter to the operands

Parameters:

filter - to add

addOperands

protected void addOperands(java.util.Collection<EventFilter> filters)

Set#addAll(Collection)Adds a collection of filters to the operands

Parameters:

filters - to add

cloneContents

protected EventFilter[] cloneContents()

Creates a new Array with clone for each contained operand

Returns:

the array of clones

getFilterCriterion

public java.lang.Object getFilterCriterion()

Description copied from class: AbstractEventFilter

Returns the unique property for an AbstractEventFilter object

Specified by:

getFilterCriterion in interface EventFilter

Specified by:

getFilterCriterion in class AbstractEventFilter

Returns:

a modifiable set of getOperands()

equals

public boolean equals(java.lang.Object obj)

Specified by:

equals in class AbstractEventFilter

setNegated

public void setNegated(boolean b)

filter cannot be negated

Overrides:

setNegated in class AbstractEventFilter

Parameters:

b - true for negating the filter, false for not

Throws:

java.lang.IllegalArgumentException

See Also:

isNegated

public boolean isNegated()

logical filters are never negated, negation is done by combining with a NotFilter

Specified by:

isNegated in interface EventFilter

Overrides:

isNegated in class AbstractEventFilter

Returns:

false

See Also:
