Method Detail

values

public static MathArithTypeEnum[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MathArithTypeEnum c : MathArithTypeEnum.values())
    System.out.println(c);

Returns:

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

valueOf

public static MathArithTypeEnum 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

getComputer

public MathArithTypeEnum.Computer getComputer(Class coercedType,
                                              Class typeOne,
                                              Class typeTwo,
                                              boolean isIntegerDivision,
                                              boolean isDivisionByZeroReturnsNull,
                                              MathContext optionalMathContext)

Returns number cruncher for the target coercion type.

Parameters:

coercedType - - target type

typeOne - - the LHS type

typeTwo - - the RHS type

isIntegerDivision - - false for division returns double, true for using Java-standard integer division

isDivisionByZeroReturnsNull - - false for division-by-zero returns infinity, true for null

optionalMathContext - - math context or null

Returns:

number cruncher

getExpressionText

public String getExpressionText()

Returns string representation of enum.

Returns:

text for enum

parseOperator

public static MathArithTypeEnum parseOperator(String operator)

Returns the math operator for the string.

Parameters:

operator - to parse

Returns:

math enum
