Method Detail

values

public static OperationType[] 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 (OperationType c : OperationType.values())
    System.out.println(c);

Returns:

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

valueOf

public static OperationType valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

getOperationTypeMode

public OperationTypeMode getOperationTypeMode()

Gets the operations type mode.

Returns:

the operations type mode

getOperationPattern

public java.util.regex.Pattern getOperationPattern()

Gets the operations pattern.

Returns:

the operations pattern

getOperationExecutionOrder

public int getOperationExecutionOrder()

Gets the operations execution order weight.

Returns:

the execution order weight

getOperationsByOperationTypeMode

public static OperationType[] getOperationsByOperationTypeMode(OperationTypeMode operationTypeMode)

Gets the operations by OperationTypeMode.

Parameters:

operationTypeMode - the OperationType

Returns:

An array for passed operationTypeMode, an empty array for passed null value

doOperation

public abstract Operand doOperation(Operand... operands)

Abstract base method to execute an operation.

Parameters:

operands - The number of operands depends on the OperationType

Returns:

The result wrapped in an Operand

Throws:

java.lang.IllegalArgumentException - if base checks for OperationType fail (like number of operands, null value checks,...)

doBaseChecks

protected void doBaseChecks(OperationType operationType,
                            Operand[] operands,
                            boolean doNullCheck,
                            boolean doSupportedTypesCheck)

This method is used to do some base checks that must be done before most operations.

This includes checks for number of operands(mandatory) and supportedTypeCheck(optional) and null checks for operation type, operands (mandatory) and operand values (optional).

Parameters:

operationType - the operation type to check for

operands - the operands of the operation

doNullCheck - Defines if null checks for operand values should be done

doSupportedTypesCheck - Defines if operand types should be checked for conformity with operation

Throws:

java.lang.IllegalArgumentException - if a constraint is violated

convertToString

protected java.lang.String convertToString(Operand operand)

Converts an operand to a String value by using it's toString method.

Parameters:

operand -

Returns:

convertToDouble

protected java.lang.Double convertToDouble(Operand operand)

Used to convert decimal and floating point numbers to a Double value.

Parameters:

operand -

Returns:

convertToLong

protected java.lang.Long convertToLong(Operand operand)

Used to convert decimal numbers to a Long value.

Parameters:

operand -

Returns:
