Function Documentation

nsQueryInterface do_VariantQueryInterface ( nsIVariant *  aVariant )

inline

Return a QI'd object for the contents of the variant specified by aVariant. This function implements do_QueryInterface for the contents of the variant.

Parameters

aVariant

Variant for which to get QI'd object.

Returns

QI'd variant content.

Definition at line 70 of file sbVariantUtilsLib.h.

nsQueryInterfaceWithError do_VariantQueryInterface ( nsIVariant *  aVariant, nsresult *  aError  )

inline

Return a QI'd object for the contents of the variant specified by aVariant and return the error result in aError. This function implements do_QueryInterface for the contents of the variant.

Parameters

aVariant	Variant for which to get QI'd object.
aError	Returned error result.

Returns

QI'd variant content.

nsresult sbVariantsEqual	(	nsIVariant *	aVariant1,
		nsIVariant *	aVariant2,
		PRBool *	aEqual
	)

Return true in aEqual if the variant specified by aVariant2 is equal to the variant specified by aVariant1; otherwise, return false. For the comparison, aVariant2 is converted to match the data type of aVariant1. If aVariant1 is an integer, and aVariant2 is a string of the form "0xde10", aVariant2 will be converted as a hexadecimal.

Parameters

aVariant1	Variants to compare.
aVariant2
aEqual	Returned true if variants are equal.
