CompareByFieldKeySetComparisonArrayFromObject Method

Sets a byte array equivalent to the field values to compare. Using this bypasses object compares, instead the byte arrays are compared byte by byte until a diff is found. If a byte diff isn't found then object compares may happen. Field types currently supported: byte, bool, Char, string, Int16, Int32, Int64, UInt16, UInt32, UInt64, Single, Double, DateTime, TimeSpan

Copy

public override void SetComparisonArrayFromObject(
	Key key,
	byte[] comparisonArray,
	bool oidShort
)

Public Overrides Sub SetComparisonArrayFromObject ( 
	key As Key,
	comparisonArray As Byte(),
	oidShort As Boolean
)

public:
virtual void SetComparisonArrayFromObject(
	Key key, 
	array<unsigned char>^ comparisonArray, 
	bool oidShort
) override

abstract SetComparisonArrayFromObject : 
        key : 'Key * 
        comparisonArray : byte[] * 
        oidShort : bool -> unit 
override SetComparisonArrayFromObject : 
        key : 'Key * 
        comparisonArray : byte[] * 
        oidShort : bool -> unit

Parameters

key: Type: Key
A key from which to extract a comparison byte array based on field(s) to compare
comparisonArray: Type: SystemByte
The array to set bytes of
oidShort: Type: SystemBoolean
If oidShort is true then only the page and slot numbers need to be compared if the comparator bytes includes any Oid bytes
