Detailed Description

Songbird Variant Utilities Source.

Function Documentation

static nsresult sbNonStringVariantToInt ( nsIVariant *  aVariant, PRInt64 *  aInt  )

static

Convert the non-string variant specified by aVariant to an integer and return the result in aInt.

Parameters

aVariant	Variant to convert.
aInt	Returned integer value.

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.

static nsresult sbVariantToInt ( nsIVariant *  aVariant, T *  aInt  )

static

Convert the variant specified by aVariant to an integer and return the result in aInt. If aVariant is a string and of the form "0xde10", it will be converted as a hexadecimal.

Parameters

aVariant	Variant to convert.
aInt	Returned integer value.
