Methods

ArrayOf(SpannerDbType)

public static SpannerDbType ArrayOf(SpannerDbType elementType)

Creates an array of the specified type. This can be done on any arbitrary SpannerDbType. You may use any type that implements IEnumerable as a source for the array. The type of each item is determined by elementType. When calling GetFieldValue<T>(String) the default type is List<T>. You may, however, specify any type that implements IList which has a default constructor.

Parameter
Name	Description
`elementType`	`SpannerDbType` The type of each item in the array.

Returns
Type	Description
`SpannerDbType`

FromClrType(Type)

public static SpannerDbType FromClrType(Type type)

Returns a SpannerDbType given a ClrType. If the type cannot be determined, Unspecified is returned.

Parameter
Name	Description
`type`	`Type` The clrType to convert.

Returns
Type	Description
`SpannerDbType`	The best Spanner representation of the given Clr Type.

GetHashCode()

public override int GetHashCode()

Returns
Type	Description
`Int32`

Overrides

Object.GetHashCode()

ToString()

public override string ToString()

Returns
Type	Description
`String`

TryParse(String, out SpannerDbType)

public static bool TryParse(string spannerType, out SpannerDbType spannerDbType)

Given a string representation, returns an instance of SpannerDbType.

Parameters
Name	Description
`spannerType`	`String` A string representation of a SpannerDbType. See ToString().
`spannerDbType`	`SpannerDbType` If parsing was successful, then an instance of SpannerDbType. Otherwise null.

Returns
Type	Description
`Boolean`	True if the parse was successful.

WithSize(Int32)

public SpannerDbType WithSize(int size)

Returns a clone of this type with the specified size constraint. Only valid on String and Bytes

Parameter
Name	Description
`size`	`Int32` Represents the number of characters (for String) or bytes (for Bytes)

Returns
Type	Description
`SpannerDbType`	A new instance of SpannerDbType with the same Google.Cloud.Spanner.Data.SpannerDbType.TypeCode and new size.
