Member Function Documentation

GetAttributeCount()

virtual GDBResult SDK_CALLTYPE GetAttributeCount ( SDKUInt32 &  count ) const throw ( )

pure virtual

Returns the number of attributes in the attribute collection.

Parameters

[out]

count

Address of a variable that receives the number of items in this collection.

Returns

kSDKResult_Succeeded.

GetAttribute()

virtual GDBResult SDK_CALLTYPE GetAttribute ( SDKUInt32  index, IAttribute **  attribute  ) throw ( )

pure virtual

Returns the attribute from the attribute collection specified by index. The first attribute has index 0 and the last attribute has index equal to AttributeCount - 1.

Parameters

[in]	index	Index of the attribute in this collection.
[out]	attribute	Address of a variable that receives the pointer to the IAttribute interface associated with the attribute.

Returns

SDKResult_Succeeded

SDKResult_InvalidArgument - Indicates an out of range index.

FindAttribute()

virtual GDBResult SDK_CALLTYPE FindAttribute ( AttributeClassCode  class_code, IAttribute **  attribute  ) throw ( )

pure virtual

Finds an attribute specified by the attribute class code.

Parameters

class_code	[in] The attribute class code.
attribute	[out] Address of a variable that receives the IAttribute interface associated with the attribute object.

Returns

kSDKResult_Succeeded

kSDKResult_NotFound - Indicates that the specified class code is not a member of this collection.

GetAttributeValue()

virtual GDBResult SDK_CALLTYPE GetAttributeValue ( AttributeClassCode  class_code, SDKAny &  value  ) throw ( )

pure virtual

Method to return the value of an attribute specified by class.

Parameters

	class_code	[in] The attribute class code.
[out]	value	Address of a variable that receives the attribute value.

Returns

kSDKResult_Succeeded.

kSDKResult_InternalError. Indicates a problem with the data.
