Enum Constant Detail

LT

public static final LocalDateOperation LT

Date less than.

LTE

public static final LocalDateOperation LTE

Date less than or equal.

GT

public static final LocalDateOperation GT

Date greater than.

GTE

public static final LocalDateOperation GTE

Date greater than or equal.

Method Detail

values

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

Returns:

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

valueOf

public static LocalDateOperation 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

execute

public Boolean execute(Interpreter interpreter,
                       List<Expression> args,
                       boolean variadicArgAsList,
                       InterpreterStackTrace stackTrace)
                throws ErrorException

Description copied from interface: Operation

Executes the expression. The operation gets the interpreter and argument expressions instead of getting evaluated arguments. This can be used for late argument evaluation or not evaluating them at all.

Specified by:

execute in interface Operation

variadicArgAsList - if true, the variadic argument is given as expression returning a list; if false, the variadic argument is given as several individual expressions

stackTrace - a stack trace passed to the interpreter

Returns:

the result of the operation

Throws:

ErrorException

exec

protected abstract Boolean exec(java.time.LocalDate left,
                                java.time.LocalDate right)

Executes the operation.

Parameters:

left -

right -

Returns:

the result

execute

public Boolean execute(Namespace namespace,
                       String oper,
                       java.time.LocalDate left,
                       java.time.LocalDate right)
