com.saxonica.functions.extfn.DeepEqual
public class DeepEqual
Implements the saxon:deep-equal() function, a variant of fn:deep-equal that provides additional control over how the comparison is performed.
The specification is as follows:
arg1 The first sequence to be compared
arg2 The second sequence to be compared
collation The collation to be used (null if the default collation is to be used)
flags A string whose characters select options that cause the comparison to vary from the standard fn:deep-equals() function. The flags are:
returns true if the sequences are deep equal, otherwise false

getMaximumNumberOfArguments in class ExtensionFunctionDefinitionpublic SequenceType[] getArgumentTypes()
getArgumentTypes in class ExtensionFunctionDefinitiongetMaximumNumberOfArguments(); however for functions
that allow a variable number of arguments, the array can be smaller than this, with the last
entry in the array providing the required type for all the remaining arguments.public SequenceType getResultType(SequenceType[] suppliedArgumentTypes)
getResultType in class ExtensionFunctionDefinitionsuppliedArgumentTypes - the static types of the arguments to the function.
This is provided so that a more precise result type can be returned in the common
case where the type of the result depends on the type of the first argument. The value
will be null if the function call has no arguments.
