Method Details

newChannelCredentials

protected io.grpc.ChannelCredentials newChannelCredentials(Map<String,?> jsonConfig)

Specified by:

newChannelCredentials in class XdsCredentialsProvider

Parameters:

jsonConfig - json config that can be consumed by the provider to create the channel credentials

getName

protected String getName()

Description copied from class: XdsCredentialsProvider

Returns the xDS credential name associated with this provider which makes it selectable via XdsCredentialsRegistry.getProvider(java.lang.String). This is called only when the class is loaded. It shouldn't change, and there is no point doing so.

Specified by:

getName in class XdsCredentialsProvider

isAvailable

public boolean isAvailable()

Description copied from class: XdsCredentialsProvider

Whether this provider is available for use, taking the current environment into consideration. If false, XdsCredentialsProvider.newChannelCredentials(java.util.Map<java.lang.String, ?>) is not safe to be called.

Specified by:

isAvailable in class XdsCredentialsProvider

priority

public int priority()

Description copied from class: XdsCredentialsProvider

A priority, from 0 to 10 that this provider should be used, taking the current environment into consideration. 5 should be considered the default, and then tweaked based on environment detection. A priority of 0 does not imply that the provider wouldn't work; just that it should be last in line.

Specified by:

priority in class XdsCredentialsProvider
