Constructor Detail

XSInteger

public XSInteger()

Initialises a representation of 0

XSInteger

public XSInteger(int x)

Initialises a representation of the supplied integer

Parameters:

x - Integer to be stored

Method Detail

string_type

public java.lang.String string_type()

Retrieves the datatype's full pathname

Overrides:

string_type in class XSDecimal

Returns:

"xs:integer" which is the datatype's full pathname

type_name

public java.lang.String type_name()

Retrieves the datatype's name

Overrides:

type_name in class XSDecimal

Returns:

"integer" which is the datatype's name

string_value

public java.lang.String string_value()

Retrieves a String representation of the integer stored

Overrides:

string_value in class XSDecimal

Returns:

String representation of the integer stored

zero

public boolean zero()

Check whether the integer represented is 0

Overrides:

zero in class XSDecimal

Returns:

True is the integer represented is 0. False otherwise

constructor

public ResultSequence constructor(ResultSequence arg)
                           throws DynamicError

Creates a new ResultSequence consisting of the extractable integer in the supplied ResultSequence

Overrides:

constructor in class XSDecimal

Parameters:

arg - The ResultSequence from which the integer is to be extracted

Returns:

New ResultSequence consisting of the integer supplied

DynamicError

int_value

public int int_value()

Retrieves the actual integer value stored

Returns:

The actual integer value stored

set_int

public void set_int(int x)

Sets the integer stored to that supplied

Parameters:

x - Integer to be stored

plus

public ResultSequence plus(ResultSequence arg)
                    throws DynamicError
