Spring Unit

This attribute marks automatically initialized interface or object fields inside of classes that inherit from TManagedObject or are using the mechanism provided by TInitTable.

Provides static methods to manipulate an enumeration type.

Provides a non-reference-counted spring4d.api/!:system.iinterface implementation.

Provides an abstract implementation for any interface implementing class without already implementing IInterface to avoid unnecessary waste of instance space for its VMT. If you inherit from this class you implement an interface that is not IInterface and thus would just waste this space.

Provides static methods to check arguments and raise argument exceptions.

Provides support for lazy initialization.

Provides an easy to use wrapper around TCriticalSection. It automatically initializes the TCriticalSection instance when required and destroys it when the Lock goes out of scope.

A nullable type can represent the normal range of values for its underlying value type, plus an additional Null value.

Provides lazy initialization routines.

A record type that stores a TValue and a name.

Helper record for fast access to nullable value via RTTI.

A record type that stores a TValue and a typeinfo.

Supports cloning, which creates a new instance of a class with the same value as an existing instance.

Defines a generalized type-specific comparison method that a class implements to order or sort its instances.

Base interface for anything that has a countable quantity.

Exposes an enumerator, which supports a simple iteration over a non-generic collection.

Supports a simple iteration over a non-generic collection.

Represents a multicast event that provides adding and removing event handlers.

Represents a multicast event that can be invoked.

Provides support for lazy initialization.

Provides support for lazy initialization.

Describes the action that caused a CollectionChanged event.

Specifies the kind of a lazy type.

Encapsulates a method that has no parameters and does not return a value.

Encapsulates a method that has four parameters and does not return a value.

Encapsulates a method that has three parameters and does not return a value.

Encapsulates a method that has two parameters and does not return a value.

Encapsulates a method that has a single parameter and does not return a value.

Encapsulates a method that has one parameter and returns a value of the type specified by the TResult parameter.

Encapsulates a method that has four parameters and returns a value of the type specified by the TResult parameter.

Encapsulates a method that has three parameters and returns a value of the type specified by the TResult parameter.

Encapsulates a method that has two parameters and returns a value of the type specified by the TResult parameter.

Encapsulates a method that has no parameters and returns a value of the type specified by the TResult parameter.

Represents the method that defines a set of criteria and determines whether the specified object meets those criteria.

Represents a instance method that has a single parameter and does not return a value.

Represents a procedure that has a single parameter and does not return a value.

An event type like TNotifyEvent that also has a generic item parameter.

Represents a anonymous method that has the same signature as TNotifyEvent.

Controls the ownership of objects stored in any associative collection.

An item was added to the collection.

An item in the collection was changed.

An item was removed from the collection without considering ownership.

An item was moved within the collection.

An item was removed from the collection.

An item was replaced in the collection.

The content of the collection changed dramatically.

Objects stored as key are being destroyed when removed

Objects stored as value are being destroyed when removed

Type is Func<TResult> .

Type is ILazy<T> .

Not a lazy type.

Type is Lazy<T> .

Raises an EArgumentNilException if the value is nil.

Raises an EArgumentNilException if the value is nil.

Compares two TValue instances.

Returns the field table for the given class that contains all fields that have Default or Managed attribute annotations.

Returns the TLazyKind of the typeInfo.

Returns the underlying type of the lazy type.

Returns the underlying type name of the lazy type.

Returns the size of the passed set type

Returns the size that is needed in order to pass an argument of the given type.

Returns the underlying type argument of the specified nullable type.

Determines whether an instance of leftType can be assigned from an instance of rightType .

Determines whether an instance of leftType can be assigned from an instance of rightType using an equality check of the typeinfo.

Returns True if the type is a lazy type.

Returns True if the type is a nullable type.

Indicates whether two Variant values are equal. Unlike using the equals operator this function also supports variant arrays.

Returns the types of the values.

Returns the length of the variant array for the specified dimension.

Determines whether a variant value is null or empty.
