Syntax

C#

public interface IUnionInstance : ISymbol, 
    IAttributedInstance, IInstance, IBitSize

The IUnionInstance type exposes the following members.

Properties

	Name	Description
	Attributes	Gets the Type Attributes. (Inherited from IAttributedInstance.)
	BitSize	Gets the size of the IDataType in bits. (Inherited from IBitSize.)
	ByteSize	Gets the (aligned) size of of the Type/Instance in Bytes (Inherited from IBitSize.)
	Category	Gets the Symbol/Datatype Category (Inherited from ISymbol.)
	Comment	Gets the comment of the IInstance (Inherited from IInstance.)
	DataType	Gets the IDataType of the IInstance. (Inherited from IInstance.)
	FieldInstances	Gets the field instances of the Union
	InstanceName	Gets the name of the instance (without periods (.) (Inherited from IInstance.)
	InstancePath	Gets the relative / absolute access path to the instance (with periods (.)) (Inherited from IInstance.)
	IsBitType	Gets a value indicating whether this instance is not basing on a full DataType but instead of some sort of bit mapping (Inherited from IBitSize.)
	IsByteAligned	Indicates that the Size of the Object is Byte aligned (BitSize % 8 == 0) (Inherited from IBitSize.)
	IsContainerType	Gets a value indicating whether this Symbol is acontainer type. (Inherited from ISymbol.)
	IsPersistent	Gets a value indicating whether this ISymbol is persistent. (Inherited from ISymbol.)
	IsPointer	Indicates that the IInstance represents a Pointer type (Pointer TO) (Inherited from IInstance.)
	IsPrimitiveType	Gets a value indicating whether this instance is a primitive type. (Inherited from ISymbol.)
	IsReadOnly	Indicates that this instance is read only. (Inherited from ISymbol.)
	IsRecursive	Gets a value indicating whether this instance is recursive. (Inherited from ISymbol.)
	IsReference	Indicates that the IInstance represents a Reference type (REFERENCE TO) (Inherited from IInstance.)
	IsStatic	Gets a value indicating whether this IInstance is static. (Inherited from IInstance.)
	Parent	Gets the parent Symbol (Inherited from ISymbol.)
	Size	Gets the size of the object in bytes or Bits dependant on IsBitType (Inherited from IBitSize.)
	SubSymbols	Gets the SubSymbols of the ISymbol (Inherited from ISymbol.)
	TypeName	Gets the name of the DataType that is used for this IInstance. (Inherited from IInstance.)
	ValueEncoding	Gets the value encoding. (Inherited from IAttributedInstance.)

Extension Methods

	Name	Description
	ReferencesExternalData	Indicates, that the Instance value includes process memory data, that cannot be read in one memory block. (Defined by DataTypeExtension.)
