Syntax

C#

public interface IMember : IField, 
    IAttributedInstance, IInstance, IBitSize

The IMember type exposes the following members.

Properties

	Name	Description
	Attributes	Gets the Type Attributes. (Inherited from IAttributedInstance)
	BitOffset	Gets the bit offset.
	BitSize	Gets the size of the IDataType in bits. (Inherited from IBitSize)
	ByteOffset	Gets the byte offset.
	ByteSize	Gets the (aligned) size of of the Type/Instance in Bytes (Inherited from IBitSize)
	Comment	Gets the comment of the IInstance (Inherited from IInstance)
	DataType	Gets the IDataType of the IInstance. (Inherited from IInstance)
	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)
	IsPointer	Indicates that the IInstance represents a Pointer type (Pointer TO) (Inherited from IInstance)
	IsProperty	Gets a value indicating whether IInstance is a property. (Inherited from IInstance)
	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)
	Offset	Gets the offset of the IMember within the parent IStructType in bits or bytes dependent on IsBitType.
	ParentType	Gets the Parent Struct/Union of this IField. (Inherited from IField)
	Size	Gets the size of the object in bytes or Bits dependant on IsBitType (Inherited from IBitSize)
	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
	HasExternalDataReferences	Indicates, that the Instance value includes process memory data, that cannot be read in one memory block. (Defined by DataTypeExtension)
	IsExternalDataReference	Indicates, that the field is static or is not part of the parents processimage memory location (Defined by DataTypeExtension)
