public final class ThreadNetworkCredentials extends Object
implements Parcelable

Data interface for managing Thread Network Credentials.

An example usage of creating Thread Network Credentials with random Active Operational Dataset:

ThreadNetworkCredentials threadCredentials =
     ThreadNetworkCredentials.newRandomizedBuilder().build();
 
or random Dataset with given Network Name:
ThreadNetworkCredentials threadCredentials =
   ThreadNetworkCredentials.newRandomizedBuilder()
     .setNetworkName("MyThreadNet")
     .build();
 
If the Thread Active Operational Dataset is already known, you can simply use:
ThreadNetworkCredentials threadCredentials =
     ThreadNetworkCredentials.fromActiveOperationalDataset(activeOperationalDataset);

Public Methods

public static ThreadNetworkCredentials fromActiveOperationalDataset (byte[] activeOperationalDataset)

Creates a new ThreadNetworkCredentials instance with given Thread Active Operational Dataset which is encoded as Thread TLV list.

Throws
IllegalArgumentException if length of activeOperationalDataset is larger than LENGTH_MAX_OPERATIONAL_DATASET, activeOperationalDataset is malformed or there are missing Thread TLVs.

public static ThreadNetworkCredentials fromIntentSenderResultData (Intent data)

Parses out the data from ThreadNetworkClient.getPreferredCredentials() or ThreadNetworkClient.getCredentialsByExtendedPanId(byte[]) IntentSender result. This method should only be called for success case to interpret the result data.

Throws
IllegalArgumentException if no valid Thread credentials included in data.

public byte[] getActiveOperationalDataset ()

Returns the Thread active operational dataset as encoded Thread TLV list.

public ThreadNetworkCredentials.Timestamp getActiveTimestamp ()

Returns the Active Timestamp in the Thread active operational dataset.

public int getChannel ()

Returns the Channel in the Thread active operational dataset.

public Set<ThreadNetworkCredentials.ChannelMaskEntry> getChannelMasks ()

Returns the Channel Masks in the Thread active operational dataset.

public int getChannelPage ()

Returns the Channel Page in the Thread active operational dataset.

public long getCreatedAtMillis ()

Returns the Unix epoch in Milliseconds the ThreadNetworkCredentials instance is created at. Note that this is the time when the Thread network credentials is first added to the Thread Network service via ThreadNetworkClient.addCredentials(ThreadBorderAgent, ThreadNetworkCredentials). Zero will be returned if this instance is not returned by ThreadNetworkClient methods (e.g. created with fromActiveOperationalDataset(byte[])).

public byte[] getExtendedPanId ()

Returns the Extended PAN ID in the Thread active operational dataset.

public byte[] getMeshLocalPrefix ()

Returns the Mesh-Local Prefix in the Thread active operational dataset.

public byte[] getNetworkKey ()

Returns the Network Key in the Thread active operational dataset.

public String getNetworkName ()

Returns the network name if it is included in the Thread active operational dataset.

public int getPanId ()

Returns the PAN ID in the Thread active operational dataset.

public byte[] getPskc ()

Returns the PSKc in the Thread active operational dataset.

public ThreadNetworkCredentials.SecurityPolicy getSecurityPolicy ()

Returns the Security Policy in the Thread active operational dataset.

public long getUpdatedAtMillis ()

Returns the Unix epoch in Milliseconds the ThreadNetworkCredentials instance is updated at. Note that this is the time when the Thread network credentials was last added/updated to the Thread Network service via ThreadNetworkClient.addCredentials(ThreadBorderAgent, ThreadNetworkCredentials). Zero will be returned if this instance is not returned by ThreadNetworkClient methods (e.g. created with fromActiveOperationalDataset(byte[])).

public static ThreadNetworkCredentials.Builder newRandomizedBuilder ()

Creates a new ThreadNetworkCredentials.Builder instance for creating ThreadNetworkCredentials instances with randomly generated credentials.

If there are requirements on specific parameters, set it explicitly with their setters in ThreadNetworkCredentials.Builder. For example, it's likely that a readable Thread Network Name should be set with ThreadNetworkCredentials.Builder.setNetworkName(String).
