WriterScalingOptions

public WriterScalingOptions(boolean isWriterTasksScalingEnabled,
 boolean isPerTaskWriterScalingEnabled,
 Optional<Integer> perTaskMaxScaledWriterCount)

Creates an instance of a WriterScalingOptions record class.

Parameters:

isWriterTasksScalingEnabled - the value for the isWriterTasksScalingEnabled record component

isPerTaskWriterScalingEnabled - the value for the isPerTaskWriterScalingEnabled record component

perTaskMaxScaledWriterCount - the value for the perTaskMaxScaledWriterCount record component

Method Details

isWriterTasksScalingEnabled

public boolean isWriterTasksScalingEnabled()

Returns the value of the isWriterTasksScalingEnabled record component.

Returns:

the value of the isWriterTasksScalingEnabled record component

isPerTaskWriterScalingEnabled

public boolean isPerTaskWriterScalingEnabled()

Returns the value of the isPerTaskWriterScalingEnabled record component.

Returns:

the value of the isPerTaskWriterScalingEnabled record component

perTaskMaxScaledWriterCount

public Optional<Integer> perTaskMaxScaledWriterCount()

Returns the value of the perTaskMaxScaledWriterCount record component.

Returns:

the value of the perTaskMaxScaledWriterCount record component

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 the compare method from their corresponding wrapper classes.

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.
