Base64BinaryValue

public Base64BinaryValue(byte[] value)

Constructor: create a base64Binary value from a given array of bytes

getBinaryValue

public byte[] getBinaryValue()

convert

public AtomicValue convert(int requiredType)
                    throws XPathException

Convert to target data type

Specified by:

convert in class AtomicValue

Parameters:

requiredType - an integer identifying the required atomic type

Returns:

an AtomicValue, a value of the required type

Throws:

XPathException - if the conversion is not possible

getStringValue

public java.lang.String getStringValue()
