Detailed Description

Represents the name and type of a field in an EventType.

Non-generic class holding the name and type of a field in an EventType (with reduced compile-time type safety compared to generic Field<T> class).

Note that the easiest way to create instances of this generic Field object is to use FieldTypes to get a FieldType object then call the FieldType<T>.NewField(string) helper method to create the Field.

Almost all new applications are recommended to use this class, instead of the legacy non-generic Field class.

The following example shows how it is possible to create a field object whose type is an Apama sequence of integers:

Field<Int64> myField = FieldTypes.Sequence(FieldTypes.Integer).NewField("myField");

Template Parameters

T	The .NET type used to represent values of this field.

For most applications, it is better to use the generic Field<T> class instead of this one, unless there is a specific requirement to process fields from Event objects without access to the corresponding generic FieldType<T> object.

Constructor & Destructor Documentation

Field() [1/2]

Apama.Event.Parser.Field< T >.Field	(	string	name,
		FieldType< T >	type
	)

Creates a new field.

Consider using FieldType<T>.NewField(string) instead of calling this method.

Parameters

name	The field name
type	the field type

Field() [2/2]

Apama.Event.Parser.Field< T >.Field	(	string	name,
		FieldType	type
	)

Creates a new field.

Parameters

name	The field name
type	the field type

Member Function Documentation

ToString()

override string Apama.Event.Parser.Field< T >.ToString

(

)

Returns a string representation of the event type. Note that this

representation will use the .NET ToString() method to format the results, and is not valid monitorscript.
