getInstance

public static ArrayFunctionSet getInstance()

getNamespace

public java.lang.String getNamespace()

Description copied from class: BuiltInFunctionSet

Return the namespace URI for the functions local to this function set.

Overrides:

getNamespace in class BuiltInFunctionSet

Returns:

the namespace URI of the functions local to this function set. Note that functions imported from another function set may have a different namespace URI.

getConventionalPrefix

public java.lang.String getConventionalPrefix()

Description copied from class: BuiltInFunctionSet

Return a conventional prefix for use with this namespace, typically the prefix used in the documentation of these functions.

Overrides:

getConventionalPrefix in class BuiltInFunctionSet

checkSubscript

public static int checkSubscript(IntegerValue subscript,
                                 int limit)
                          throws XPathException

Check that a number proposed for use as a subscript is greater than zero and less than the maximum subscript allowed by the implementation (2^31-1), returning the value as a Java int

Parameters:

subscript - the proposed subscript (one-based)

limit - the upper limit allowed (usually the size of the array, sometimes arraysize + 1)

Returns:

the proposed subscript as an int, if it is in range (still one-based)

Throws:

XPathException - if the subscript is 0, negative, or outside the permitted range
