Method Detail

any

public static ArrayExpressionIn any(VariableExpression variable)

Creates an ANY Quantified operator (ANY IN SATISFIES ) with the given variable name. The method returns an IN clause object that is used for specifying an array object or an expression evaluated as an array object, each item of which will be evaluated against the satisfies expression. The ANY operator returns TRUE if at least one of the items in the array satisfies the given satisfies expression.

Parameters:

variable - The variable expression.

Returns:

An In object

every

public static ArrayExpressionIn every(VariableExpression variable)

Creates an EVERY Quantified operator (EVERY IN SATISFIES ) with the given variable name. The method returns an IN clause object that is used for specifying an array object or an expression evaluated as an array object, each of which will be evaluated against the satisfies expression. The EVERY operator returns TRUE if the array is empty OR every item in the array satisfies the given satisfies expression.

Parameters:

variable - The variable expression.

Returns:

An In object.

anyAndEvery

public static ArrayExpressionIn anyAndEvery(VariableExpression variable)

Creates an ANY AND EVERY Quantified operator (ANY AND EVERY IN SATISFIES ) with the given variable name. The method returns an IN clause object that is used for specifying an array object or an expression evaluated as an array object, each of which will be evaluated against the satisfies expression. The ANY AND EVERY operator returns TRUE if the array is NOT empty, and at least one of the items in the array satisfies the given satisfies expression.

Parameters:

variable - The variable expression.

Returns:

An In object.

variable

public static VariableExpression variable(String name)

Creates a variable expression. The variable are used to represent each item in an array in the quantified operators (ANY/ANY AND EVERY/EVERY IN SATISFIES ) to evaluate expressions over an array.

Parameters:

name - The variable name

Returns:

A variable expression
