setResourceTimingBufferSize

Summary

Sets the maximum number of PerformanceResourceTiming resources that may be stored in the buffer to the value of the maxSize parameter.

Method of apis/resource_timing/Performanceapis/resource_timing/Performance

Syntax

 .setResourceTimingBufferSize(maxSize);

Parameters

maxSize

Data-type

unsigned long

The maximum number of PerformanceResourceTiming resources that will be stored in the buffer.

Return Value

No return value

Examples

This example uses clearResourceTimings and setResourceTimingBufferSize to set an initial buffer size. It then uses onresourcetimingbufferfull to detect when the buffer is full, and executes a function that uses clearResourceTimings to clear the buffer.

performance.clearResourceTimings();
setResourceTimingBufferSize(100);

function buffFull() {
  performance.clearResourceTimings();
  };

performance.onresourcetimingbufferfull = buffFull;

Notes

The setResourceTimingBufferSize does not take effect until the clearResourceTimings method is called.
