Method Details

values

public static Formula.AverageMethod[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Formula.AverageMethod valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

fromValue

public static Formula.AverageMethod fromValue(int value)

Get the Formula.AverageMethod object when you know the integer code.

Parameters:

value - The integer value.

Returns:

The AverageMethod object or null if the value is unknown

getAverageExpression

public abstract Expression getAverageExpression(Expression e)

Given an expression, create an expression that takes the correct average of it.

Parameters:

e - The expression, null is not allowed

Returns:

The average expression, or null if it is not possible to create an average expression

getValue

public int getValue()

Get the integer value that is used when storing a Formula.AverageMethod in the database.

Returns:

The integer value of this type

toString

public String toString()

Overrides:

toString in class Enum<Formula.AverageMethod>
