Method Detail

apply2

public Object apply2(Object arg1, Object arg2)

apply2

public static boolean apply2(int flags, Object arg1, Object arg2)

applyN

public Object applyN(Object[] args)

applyWithPromotion

public static boolean applyWithPromotion(int flags, Object arg1, Object arg2)

checkCompareCode

public static boolean checkCompareCode(int code, int flags)

compare

public static int compare(Object arg1, Object arg2, boolean exact)

Compare two numbers.

Parameters: exact true if we should compare exact/inexact numbers exactly (by converting the inexact number to exact), or inexactly (by "promoting" the exact to inexact) (as required for XQuery).

Returns: 1 if {@code arg1>arg2}; 0 if {@code arg1==arg2}; -1 if {@code arg1
