Constructor Details

OutputStatsEstimateResult

public OutputStatsEstimateResult(com.google.common.primitives.ImmutableLongArray partitionDataSizes,
 long outputRowCountEstimate,
 String kind,
 boolean isAccurate)

OutputStatsEstimateResult

public OutputStatsEstimateResult(OutputDataSizeEstimate outputDataSizeEstimate,
 long outputRowCountEstimate,
 String kind,
 boolean isAccurate)

Creates an instance of a OutputStatsEstimateResult record class.

Parameters:

outputDataSizeEstimate - the value for the outputDataSizeEstimate record component

outputRowCountEstimate - the value for the outputRowCountEstimate record component

kind - the value for the kind record component

isAccurate - the value for the isAccurate record component

Method Details

unknown

public static OutputStatsEstimator.OutputStatsEstimateResult unknown()

isUnknown

public boolean isUnknown()

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.

outputDataSizeEstimate

public OutputDataSizeEstimate outputDataSizeEstimate()

Returns the value of the outputDataSizeEstimate record component.

Returns:

the value of the outputDataSizeEstimate record component

outputRowCountEstimate

public long outputRowCountEstimate()

Returns the value of the outputRowCountEstimate record component.

Returns:

the value of the outputRowCountEstimate record component

kind

public String kind()

Returns the value of the kind record component.

Returns:

the value of the kind record component

isAccurate

public boolean isAccurate()

Returns the value of the isAccurate record component.

Returns:

the value of the isAccurate record component
