Detailed Description

CPComparisonPredicate is a subclass of CPPredicate used to compare expressions.

Comparison predicates are predicates used to compare the results of two expressions. Comparison predicates take an operator, a left expression, and a right expression, and return as a BOOL the result of invoking the operator with the results of evaluating the expressions. Expressions are represented by instances of the CPExpression class.

Method Documentation

◆ comparisonPredicateModifier()

- (CPComparisonPredicateModifier) comparisonPredicateModifier

implementation

Returns the comparison predicate modifier for the receiver.

Returns: The comparison predicate modifier for the receiver.

Definition at line 136 of file CPComparisonPredicate.j.

◆ customSelector()

- (SEL) customSelector

implementation

Returns the selector for the receiver.

Returns: The selector for the receiver, or NULL if there is none.

Definition at line 145 of file CPComparisonPredicate.j.

◆ encodeWithCoder:()

- (void) encodeWithCoder: (CPCoder) coder

implementation

Provided by category CPComparisonPredicate(CPCoding).

Definition at line 415 of file CPComparisonPredicate.j.

◆ evaluateWithObject:()

- (BOOL) evaluateWithObject: (id) object

implementation

Definition at line 359 of file CPComparisonPredicate.j.

◆ evaluateWithObject:substitutionVariables:()

- (BOOL) evaluateWithObject:	(id)	object
substitutionVariables:	(CPDictionary)	variables

implementation

Definition at line 364 of file CPComparisonPredicate.j.

◆ initWithCoder:()

- (id) initWithCoder: (CPCoder) coder

implementation

Provided by category CPComparisonPredicate(CPCoding).

Definition at line 399 of file CPComparisonPredicate.j.

◆ initWithLeftExpression:rightExpression:customSelector:()

- (id) initWithLeftExpression:	(CPExpression)	left
rightExpression:	(CPExpression)	right
customSelector:	(SEL)	selector

implementation

Initializes a predicate formed by combining given left and right expressions using a given selector.

Parameters

left	The left hand side expression.
right	The right hand side expression.
selector	The selector to use for comparison. The method defined by the selector must take a single argument and return a BOOL value.

Returns: The receiver, initialized by combining the left and right expressions using selector.

Definition at line 82 of file CPComparisonPredicate.j.

◆ initWithLeftExpression:rightExpression:modifier:type:options:()

- (id) initWithLeftExpression:	(CPExpression)	left
rightExpression:	(CPExpression)	right
modifier:	(CPComparisonPredicateModifier)	modifier
type:	(CPPredicateOperatorType)	type
options:	(unsigned)	options

implementation

Initializes a predicate to a given type formed by combining given left and right expressions using a given modifier and options.

Parameters

left	The left hand expression.
right	The right hand expression.
modifier	The modifier to apply.
type	The predicate operator type.
options	The options to apply (see CPComparisonPredicate Options).

Returns: The receiver, initialized to a predicate of type type formed by combining the left and right expressions using the modifier and options.

Definition at line 108 of file CPComparisonPredicate.j.

◆ isEqual:()

- (BOOL) isEqual: (id) anObject

implementation

Definition at line 265 of file CPComparisonPredicate.j.

◆ leftExpression()

- (CPExpression) leftExpression

implementation

Returns the left expression for the receiver.

Returns: The left expression for the receiver, or nil if there is none.

Definition at line 154 of file CPComparisonPredicate.j.

◆ options()

- (unsigned) options

implementation

Returns the options that are set for the receiver.

Returns: The options that are set for the receiver.

Definition at line 163 of file CPComparisonPredicate.j.

◆ predicateFormat()

- (CPString) predicateFormat

implementation

Definition at line 186 of file CPComparisonPredicate.j.

◆ predicateOperatorType()

- (CPPredicateOperatorType) predicateOperatorType

implementation

Returns the predicate type for the receiver.

Returns: Returns the predicate type for the receiver.

Definition at line 172 of file CPComparisonPredicate.j.

◆ predicateWithLeftExpression:rightExpression:customSelector:()

+ (CPPredicate) predicateWithLeftExpression:	(CPExpression)	left
rightExpression:	(CPExpression)	right
customSelector:	(SEL)	selector

implementation

Returns a new predicate formed by combining the left and right expressions using a given selector.

Parameters

left	The left hand side expression.
right	The right hand side expression.
selector	The selector to use for comparison. The method defined by the selector must take a single argument and return a BOOL value.

Returns: A new predicate formed by combining the left and right expressions using selector.

Definition at line 56 of file CPComparisonPredicate.j.

◆ predicateWithLeftExpression:rightExpression:modifier:type:options:()

+ (CPPredicate) predicateWithLeftExpression:	(CPExpression)	left
rightExpression:	(CPExpression)	right
modifier:	(CPComparisonPredicateModifier)	modifier
type:	(int)	type
options:	(unsigned)	options

implementation

Creates and returns a predicate of a given type formed by combining given left and right expressions using a given modifier and options.

Parameters

left	The left hand expression.
right	The right hand expression.
modifier	The modifier to apply.
type	The predicate operator type.
options	The options to apply (see CPComparisonPredicate Options).

Returns: A new predicate of type type formed by combining the given left and right expressions using the modifier and options.

Definition at line 70 of file CPComparisonPredicate.j.

◆ predicateWithSubstitutionVariables:()

- (CPPredicate) predicateWithSubstitutionVariables: (CPDictionary) variables

implementation

Definition at line 254 of file CPComparisonPredicate.j.

◆ rightExpression()

- (CPExpression) rightExpression

implementation
