Record Class DataStreamFailureStore.Template

java.lang.Object

java.lang.Record

org.elasticsearch.cluster.metadata.DataStreamFailureStore.Template

All Implemented Interfaces:

Writeable, ToXContent, ToXContentObject

Enclosing class:

DataStreamFailureStore

public static record DataStreamFailureStore.Template(ResettableValue<Boolean> enabled)
extends Record
implements Writeable, ToXContentObject

This class is only used in template configuration. It wraps the fields of DataStreamFailureStore with ResettableValue to allow a user to signal when they want to reset any previously encountered values during template composition. Furthermore, it provides the method merge(Template, Template) that dictates how two templates can be composed.

Constructor Details

Template

public Template(ResettableValue<Boolean> enabled)

Creates an instance of a Template record class.

Parameters:

enabled - the value for the enabled record component

Method Details

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Throws:

IOException

read

public static DataStreamFailureStore.Template read(StreamInput in)
                                            throws IOException

Throws:

IOException

toXContent

public XContentBuilder toXContent(XContentBuilder builder,
 ToXContent.Params params)
                           throws IOException

Converts the template to XContent, depending on the XContent.Params set by ResettableValue.hideResetValues(Params) it may or may not display any explicit nulls when the value is to be reset.

Specified by:

toXContent in interface ToXContent

Throws:

IOException

fromXContent

public static DataStreamFailureStore.Template fromXContent(XContentParser parser)
                                                    throws IOException

Throws:

IOException

merge

public static DataStreamFailureStore.Template merge(DataStreamFailureStore.Template ignored,
 DataStreamFailureStore.Template update)

Returns a template which has the value of the initial template updated with the values of the update. Note: for now it's a trivial composition because we have only one non-null field.

Returns:

the composed template

toFailureStore

public DataStreamFailureStore toFailureStore()

toString

public String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

enabled

public ResettableValue<Boolean> enabled()

Returns the value of the enabled record component.

Returns:

the value of the enabled record component
