KeyCondition

public KeyCondition(Id commandId,
 Id targetNodeId,
 String key,
 Id expectedChild)

Creates an instance of a KeyCondition record class.

Parameters:

commandId - the value for the commandId record component

targetNodeId - the value for the targetNodeId record component

key - the value for the key record component

expectedChild - the value for the expectedChild 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. 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.

commandId

public Id commandId()

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

key

public String key()

Returns the value of the key record component.

Returns:

the value of the key record component

expectedChild

public Id expectedChild()

Returns the value of the expectedChild record component.

Returns:

the value of the expectedChild record component
