#### error : Error
Core/TileProviderError.js 83

  The error or exception that occurred, if any.

#### level : Number

  The message describing the error.

#### provider : ImageryProvider|TerrainProvider
Core/TileProviderError.js 34

  The `ImageryProvider` or `TerrainProvider` that experienced the error.

#### retry : Boolean
Core/TileProviderError.js 77

  True if the failed operation should be retried; otherwise, false. The imagery or terrain provider will set the initial value of this property before raising the event, but any listeners can change it. The value after the last listener is invoked will be acted upon.
  Default Value: `false`

  The number of times this operation has been retried.
  Default Value: `0`

#### x : Number

### Methods

#### staticCesium.TileProviderError.handleError(previousError, provider, event, message, x, y, level, retryFunction, errorDetails) → TileProviderError
Core/TileProviderError.js 111

  Handles an error in an `ImageryProvider` or `TerrainProvider` by raising an event if it has any listeners, or by logging the error to the console if the event has no listeners. This method also tracks the number of times the operation has been retried and will automatically retry if requested to do so by the event listeners.

  Name | Type | Description
  --- | --- | ---
  `previousError` | TileProviderError | The error instance returned by this function the last time it was called for this error, or undefined if this is the first time this error has occurred.
  `provider` | ImageryProvider | TerrainProvider | The imagery or terrain provider that encountered the error.
  `event` | Event | The event to raise to inform listeners of the error.
  `message` | String | The message describing the error.
  `x` | Number | The X coordinate of the tile that experienced the error, or undefined if the error is not specific to a particular tile.
  `y` | Number | The Y coordinate of the tile that experienced the error, or undefined if the error is not specific to a particular tile.
  `level` | Number | The level-of-detail of the tile that experienced the error, or undefined if the error is not specific to a particular tile.
  `retryFunction` | TileProviderError~RetryFunction | The function to call to retry the operation. If undefined, the operation will not be retried.
  `errorDetails` | Error | optional The error or exception that occurred, if any.

  ##### Returns:

  The error instance that was passed to the event listeners and that should be passed to this function the next time it is called for the same error in order to track retry counts.

#### staticCesium.TileProviderError.handleSuccess(previousError)
Core/TileProviderError.js 146

  Handles success of an operation by resetting the retry count of a previous error, if any. This way, if the error occurs again in the future, the listeners will be informed that it has not yet been retried.

  Name | Type | Description
  --- | --- | ---
  `previousError` | TileProviderError | The previous error, or undefined if this operation has not previously resulted in an error.

### Type Definitions

#### RetryFunction()
Core/TileProviderError.js 152

  A function that will be called to retry the operation.
