PostSharp.Patterns.Contracts Namespace

This namespace contains ready-made contracts that validate fields, properties and parameters at runtime.

Classes

	Class	Description
	ContractExceptionFactory	Base class for contract exception factories. Implements chain of responsibility between concrete exception factories.
	ContractExceptionInfo	This class holds the information from which the ContractExceptionFactory should create the exception.
	ContractLocalizedTextProvider	Base class for contract error messages providers.
	ContractServices	This class provides services supporting Contract aspects. By adding your own classes to the ExceptionFactory chain, you can change the way the exceptions are created when a contract is broken. By plugging into the LocalizedTextProvider chain, you can change the way the exception messages are generated. See the documentation for the classes for more details: ContractLocalizedTextProvider, ContractExceptionFactory.
	CreditCardAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentException if the target is assigned a value that is not a valid credit card number. Null strings are accepted and do not throw an exception.
	DefaultContractExceptionFactory	Default implementation of ContractExceptionFactory.
	EmailAddressAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentException if the target is assigned a value that is not a valid email address. Null strings are accepted and do not throw an exception.
	EnumDataTypeAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentException if the target is assigned a value that is not a valid member of an enumeration.
	GreaterThanAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value that is smaller than a given value.
	LessThanAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value that is greater than a given value.
	LocationContractAttribute	Base class for other custom attributes in this namespace.
	NegativeAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value greater than zero.
	NotEmptyAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentNullException if the target is assigned a null or empty value. The custom attributes can be added to locations of type String (where empty means zero characters), or ICollection, ICollection<T> or IReadOnlyCollection<T> (where empty means zero items).
	NotNullAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentNullException if the target is assigned a null value.
	PhoneAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentException if the target is assigned a value that is not a valid phone number. Null strings are accepted and do not throw an exception.
	PositiveAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value smaller than zero.
	PostconditionFailedException	The exception that is thrown when a postcondition contract was not fulfilled by a method.
	RangeAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value that is outside a given range.
	RegularExpressionAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentException if the target is assigned a value that does not match a given regular expression. Null strings are accepted and do not throw an exception.
	RequiredAttribute	Custom attribute that, when added to a field, property or parameter, throws: an ArgumentNullException if the target is assigned a null value; an ArgumentOutOfRangeException if the target is assigned an empty or white-space string.
	StrictlyGreaterThanAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value that is smaller than or equal to a given value.
	StrictlyLessThanAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value that is greater than or equal to a given value.
	StrictlyNegativeAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value greater than or equal to zero.
	StrictlyPositiveAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value smaller than or equal to zero.
	StrictRangeAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentOutOfRangeException if the target is assigned a value that is not strictly within the given range.
	StringLengthAttribute	Custom attribute that, when added to a field, property or parameter, throws an ArgumentException if the target is assigned a string of invalid length. Null strings are accepted and do not throw an exception.
