Constructor Details

DemographicSnapshot

public DemographicSnapshot(TimeCoordinate date,
 long population,
 double growthRate,
 String region,
 double reliability)

Creates an instance of a DemographicSnapshot record class.

Parameters:

date - the value for the date record component

population - the value for the population record component

growthRate - the value for the growthRate record component

region - the value for the region record component

reliability - the value for the reliability 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 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.

date

public TimeCoordinate date()

Returns the value of the date record component.

Returns:

the value of the date record component

population

public long population()

Returns the value of the population record component.

Returns:

the value of the population record component

growthRate

public double growthRate()

Returns the value of the growthRate record component.

Returns:

the value of the growthRate record component

region

public String region()

Returns the value of the region record component.

Returns:

the value of the region record component

reliability

public double reliability()

Returns the value of the reliability record component.

Returns:

the value of the reliability record component
