Enum Constant Summary

Enum Constants

Enum Constant and Description
EXPRESSION If an argument type to an OperatorGenerator is of the EXPRESSION type, then the text that appears in an invocation of the operator generator should be compilable as a valid expression in its own right.
EXPRESSIONWITHSCOPE If an argument type to an OperatorGenerator is of the EXPRESSIONWITHSCOPE type, then the text that appears in an invocation of the operator generator should be compilable as a valid expression in the scope generated by another expression.
STRING If an argument type to an OperatorGenerator is of the STRING type, then the text that appears in an invocation of the operator generator denotes "amends" that allow to "generate" the specifics of the operator.

Enum Constant Detail

EXPRESSION

public static final OperatorGeneratorArgumentType EXPRESSION

If an argument type to an OperatorGenerator is of the EXPRESSION type, then the text that appears in an invocation of the operator generator should be compilable as a valid expression in its own right. Examples are the relation arguments that are subjected to JOIN,RESTRICTion,SUMMARIZE,etc.

EXPRESSIONWITHSCOPE

public static final OperatorGeneratorArgumentType EXPRESSIONWITHSCOPE

If an argument type to an OperatorGenerator is of the EXPRESSIONWITHSCOPE type, then the text that appears in an invocation of the operator generator should be compilable as a valid expression in the scope generated by another expression. Examples are the expression arguments with which RESTRICTions, EXTENDs, AGGREGATEs and SUMMARIZEs are "amended".

STRING

public static final OperatorGeneratorArgumentType STRING

If an argument type to an OperatorGenerator is of the STRING type, then the text that appears in an invocation of the operator generator denotes "amends" that allow to "generate" the specifics of the operator. Examples are the attribute list in PROJECTions, the attribute rename list in RENAMEs, ...

Method Detail

values

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

Returns:

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

valueOf

public static OperatorGeneratorArgumentType 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
