Record Class SignalCommand.IncrementCommand

java.lang.Object

java.lang.Record

com.vaadin.signals.SignalCommand.IncrementCommand

Record Components:

commandId - the unique command id used to track the status of this command instance, not null

targetNodeId - id of the node to update, not null

delta - a double value to increment by

All Implemented Interfaces:

SignalCommand

Enclosing interface:

SignalCommand

public static record SignalCommand.IncrementCommand(Id commandId, Id targetNodeId, double delta)
extends Record
implements SignalCommand

Increments the value of the given node by the given delta. The node must have a numerical value. If the node has no value at all, then 0 is used as the previous value. A negative delta value leads to decrementing the value.

Constructor Details

IncrementCommand

public IncrementCommand(Id commandId,
 Id targetNodeId,
 double delta)

Creates an instance of a IncrementCommand record class.

Parameters:

commandId - the value for the commandId record component

targetNodeId - the value for the targetNodeId record component

delta - the value for the delta record component

Method Details

toString

public final 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. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

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.

commandId

public Id commandId()

Returns the value of the commandId record component.

Specified by:

commandId in interface SignalCommand

Returns:

the value of the commandId record component

targetNodeId

public Id targetNodeId()

Returns the value of the targetNodeId record component.

Specified by:

targetNodeId in interface SignalCommand

Returns:

the value of the targetNodeId record component

delta

public double delta()

Returns the value of the delta record component.

Returns:

the value of the delta record component
