Detailed Description

Provides factory methods and constants for getting all supported Apama event field types.

The following example shows how it is possible to create a field object whose type is an Apama sequence of integers: var myField = FieldTypes.Sequence(FieldTypes.Integer).NewField("myField");

Member Function Documentation

static ReferenceFieldType<IDictionary<TKey, TValue> > Apama.Event.Parser.FieldTypes.Dictionary< TKey, TValue > ( FieldType< TKey >  keyType, FieldType< TValue >  valueType  )

static

Create a new field type object for an Apama dictionary event field.

Template Parameters

TKey	The .NET type used to represent the key of items in this dictionary.
TValue	The .NET type used to represent the value of items in this dictionary.

Parameters

keyType	The event field type for the key of items in this dictionary.
valueType	The event field type for the value of items in this dictionary.

Returns

A new object representing this field type, which can be used in the constructor to EventType.

static FieldType<T?> Apama.Event.Parser.FieldTypes.Optional< T > ( PrimitiveFieldType< T >  containedType )

static

Create an optional field type object with a primitive containedType Apama event field.

To create an optional event field of Integer, Boolean and Float fieldTypes with field names of "intField", "boolField" and "doubleField" respectively:

Field<long?> intField = FieldTypes.Optional(FieldTypes.Integer).NewField("intField");

Field<bool?> boolField = FieldTypes.Optional(FieldTypes.Boolean).NewField("boolField");

Field<double?> dblField = FieldTypes.Optional(FieldTypes.Float).NewField("doubleField");

Template Parameters

T	The .NET type used to represent the value contained in this optional field.

Parameters

containedType

The event field type for the contained element in this field.

Returns

A new object representing this field type, which can be used in the constructor to EventType.

Type Constraints

T

:

struct

static FieldType<T> Apama.Event.Parser.FieldTypes.Optional< T > ( ReferenceFieldType< T >  containedType )

static

Create an optional field type with a referenced containedType Apama event field.

To create an optional event field of Decimal, Sequence of Integer and an EventType type with field names of "decField", "seqIntField" and "evtField" respectively:

Field<DecimalFieldValue> decField = FieldTypes.Optional(FieldTypes.Decimal).NewField("decField");

Field<IList<long>> optSeqIntField = FieldTypes.Optional(FieldTypes.Sequence(FieldTypes.Integer)).NewField("seqIntField");

Field<Event> optSubEventField = FieldTypes.Optional(subEventType).NewField("evtField");

Template Parameters

T	The .NET type used to represent the value contained in this optional field.

Parameters

containedType

The event field type for the contained element in this field.

Returns

A new object representing this field type, which can be used in the constructor to EventType.

Type Constraints

T

:

class

static ReferenceFieldType<IList<E> > Apama.Event.Parser.FieldTypes.Sequence< E > ( FieldType< E >  elementType )

static

Create a new field type object for an Apama sequence event field.

Template Parameters

E	The .NET type used to represent values in this sequence.

Parameters

elementType

The event field type for the elements in this sequence.

Returns

A new object representing this field type, which can be used in the constructor to EventType.
