Description

An AGSUtilityTraceFunctionBarrier object stops continued traversal when a comparison expression evaluates as YES.

An AGSUtilityTraceFunctionBarrier object performs a comparison expression between the current results of an AGSUtilityTraceFunction object and a given value. Remember that an AGSUtilityTraceFunction object references an AGSUtilityNetworkAttribute object and a calculation that is applied to it (min, max, count, etc.) Once the comparison evaluates as YES, the network traversal stops.

◆ initWithTraceFunction:comparisonOperator:value:

- (instancetype) initWithTraceFunction:	(AGSUtilityTraceFunction *)	traceFunction
comparisonOperator:	(AGSUtilityAttributeComparisonOperator)	comparisonOperator
value:	(id)	value

Creates a barrier that stops tracing when an AGSUtilityTraceFunction object compared to a value evaluates to YES.

Parameters

traceFunction	The calculation to perform.
comparisonOperator	The operator used for the comparison.
value	The value to compare against.

Since: 100.7

◆ utilityTraceFunctionBarrierWithTraceFunction:comparisonOperator:value:

+ (instancetype) utilityTraceFunctionBarrierWithTraceFunction:	(AGSUtilityTraceFunction *)	traceFunction
comparisonOperator:	(AGSUtilityAttributeComparisonOperator)	comparisonOperator
value:	(id)	value

Creates a barrier that stops tracing when an AGSUtilityTraceFunction object compared to a value evaluates to YES.

Parameters

traceFunction	The calculation to perform.
comparisonOperator	The operator used for the comparison.
value	The value to compare against.

Returns: A new barrier object.
