Method Details

getHostname

@Nullable
public String getHostname()

System's hostname. null in case of UnknownHostException

getVersion

public Version getVersion()

The current ES version

getBuild

public Build getBuild()

The build version of the node.

getSettings

@Nullable
public Settings getSettings()

The settings of the node.

getInfo

public <T extends ReportingService.Info> T getInfo(Class<T> clazz)

Get a particular info object, e.g. JvmInfo or OsInfo. This generic method handles all casting in order to spare client classes the work of explicit casts. This NodeInfo class guarantees type safety for these stored info blocks.

Type Parameters:

T - Specific subtype of ReportingService.Info to retrieve.

Parameters:

clazz - Class for retrieval.

Returns:

An object of type T.

getTotalIndexingBuffer

@Nullable
public ByteSizeValue getTotalIndexingBuffer()

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Overrides:

writeTo in class BaseNodeResponse

Throws:

IOException
