The ISymbol 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
	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.)
	IsContainerType	Gets a value indicating whether this Symbol is acontainer type.
	IsPersistent	Gets a value indicating whether this ISymbol is persistent.
	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.
	IsReadOnly	Indicates that this instance is read only.
	IsRecursive	Gets a value indicating whether this instance is recursive.
	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
	Size	Gets the size of the object in bytes or Bits dependant on IsBitType (Inherited from IBitSize.)
	SubSymbols	Gets the SubSymbols of the 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.)
