方法概要

所有方法实例方法具体方法
限定符和类型	方法和说明
`ChartRepository.Index`	`clearIndex()` Clears the `ChartRepository.Index` stored internally by this `ChartRepository`, paving the way for a fresh copy to be installed by the `getIndex(boolean)` method, and returns the old value.
`Path`	`downloadIndex()` Invokes the `downloadIndexTo(Path, CopyOption...)` method with the return value of the `getCachedIndexPath()` method as its first parameter value, and `StandardCopyOption.REPLACE_EXISTING` as its second parameter value.
`@Issue(id="156",uri="https://github.com/microbean/microbean-helm/issues/156") Path`	`downloadIndex(CopyOption... copyOptions)` Invokes the `downloadIndexTo(Path, CopyOption...)` method with the return value of the `getCachedIndexPath()` method.
`Path`	`downloadIndexTo(Path path)` Downloads a copy of the chart repository's `index.yaml` file to the `Path` specified and returns the canonical representation of the `Path` to which the file was actually downloaded.
`@Issue(id="156",uri="https://github.com/microbean/microbean-helm/issues/156") Path`	`downloadIndexTo(Path path, CopyOption... copyOptions)` Downloads a copy of the chart repository's `index.yaml` file to the `Path` specified and returns the canonical representation of the `Path` to which the file was actually downloaded.
`Path`	`getCachedChartPath(String chartName, String chartVersion)` Given a Helm chart name and its version, returns the local `Path`, representing a local copy of the Helm chart as downloaded from the chart repository represented by this `ChartRepository`, downloading the archive if necessary, and replacing any prior copy that may exist.
`@Issue(id="156",uri="https://github.com/microbean/microbean-helm/issues/156") Path`	`getCachedChartPath(String chartName, String chartVersion, CopyOption... copyOptions)` Given a Helm chart name and its version, returns the local `Path`, representing a local copy of the Helm chart as downloaded from the chart repository represented by this `ChartRepository`, downloading the archive if necessary.
`Path`	`getCachedIndexPath()` Returns a non-`null`, absolute `Path` to the file that contains or will contain a copy of the chart repository's `index.yaml` file.
`ChartRepository.Index`	`getIndex()` Returns the `ChartRepository.Index` for this `ChartRepository`.
`ChartRepository.Index`	`getIndex(boolean forceDownload)` Returns the `ChartRepository.Index` for this `ChartRepository`.
`@Issue(id="156",uri="https://github.com/microbean/microbean-helm/issues/156") ChartRepository.Index`	`getIndex(boolean forceDownload, CopyOption... copyOptions)` Returns the `ChartRepository.Index` for this `ChartRepository`.
`String`	`getName()` Returns the name of this `ChartRepository`.
`URI`	`getUri()` Returns the `URI` of the root of this `ChartRepository`.
`boolean`	`isCachedIndexExpired()` Returns `true` if the cached copy of the `index.yaml` file is to be considered stale.
`ChartRepository.Index`	`loadIndex()` Creates a new `ChartRepository.Index` from the contents of the cached copy of the chart repository's `index.yaml` file and returns it.
`protected InputStream`	`openStream(URL url)` Returns an `InputStream` corresponding to the supplied `URL`.
`ChartOuterClass.Chart.Builder`	`resolve(String chartName, String chartVersion)` Uses the supplied `chartName` and `chartVersion` parameters to find an appropriate Helm chart and returns it in the form of a `Chart.Builder` object.

    Invokes the downloadIndexTo(Path, CopyOption...) method with the return value of the getCachedIndexPath() method.
    This method never returns null.
    
    参数:
    
    copyOptions - any CopyOption instances that will be passed to any Files.move(Path, Path, CopyOption...) invocations that may be necessary; may be null
    
    返回:
    
    Path the Path to which the index.yaml file was downloaded; never null
    
    抛出:
    
    IOException - if there was a problem downloading

public Path downloadIndexTo(Path path)
                     throws IOException
```
    Downloads a copy of the chart repository's index.yaml file to the Path specified and returns the canonical representation of the Path to which the file was actually downloaded.
    This method never returns null.
    
    Overrides of this method must not return null.
    
    The default implementation of this method actually downloads the index.yaml file to a temporary file first, and then renames it, replacing any existing file with that name.
    
    参数:
    
    path - the Path to download the index.yaml file to; may be null in which case the return value of the getCachedIndexPath() method will be used instead
    
    返回:
    
    the Path to the file; never null
