Enum Constant Detail

GT

public static final RelationalOpEnum GT

Greater then.

GE

public static final RelationalOpEnum GE

Greater equals.

LT

public static final RelationalOpEnum LT

Lesser then.

LE

public static final RelationalOpEnum LE

Lesser equals.

Method Detail

values

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

Returns:

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

valueOf

public static RelationalOpEnum 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

reversed

public RelationalOpEnum reversed()

parse

public static RelationalOpEnum parse(java.lang.String op)

Parses the operator and returns an enum for the operator.

Parameters:

op - to parse

Returns:

enum representing relational operation

getComputer

public RelationalOpEnum.Computer getComputer(java.lang.Class coercedType,
                                             java.lang.Class typeOne,
                                             java.lang.Class typeTwo)

Returns the computer to use for the relational operation based on the coercion type.

Parameters:

coercedType - is the object type

typeOne - the compare-to type on the LHS

typeTwo - the compare-to type on the RHS

Returns:

computer for performing the relational op

getExpressionText

public java.lang.String getExpressionText()

Returns string rendering of enum.

Returns:

relational op string
