Constructor Detail

SimpleValue

public SimpleValue()

Construct an empty SimpleValue. Also used by the ExternalizableLite implementation.

SimpleValue

public SimpleValue(Object oValue)

Construct a SimpleValue. This form constructs an element's content value from the passed Object value. If the Object is a String, then the String should be un-escaped by this point; it must not still be in the form of the CDATA construct.

Parameters:

oValue - the initial value for this SimpleValue

Throws:

IllegalArgumentException - if the String value is illegal

SimpleValue

public SimpleValue(Object oValue,
                   boolean fAttribute)

Construct a SimpleValue. This form constructs an element's content or attribute value from the passed String value. The String should be un-escaped by this point; it must not still be in the form of the CDATA construct.

Parameters:

oValue - the initial value for this SimpleValue

fAttribute - true if this SimpleValue is an element attribute value; false if an element's content's value

Throws:

IllegalArgumentException - if the String value is illegal

SimpleValue

public SimpleValue(Object oValue,
                   boolean fAttribute,
                   boolean fReadOnly)

Construct a SimpleValue. This form constructs an element's content or attribute value from the passed String value, and also allows the caller to specify that the value is immutable. The String should be un-escaped by this point; it must not still be in the form of the CDATA construct.

Parameters:

oValue - the initial value for this SimpleValue

fAttribute - true if this SimpleValue is an element attribute value; false if an element's content's value

fReadOnly - true if this SimpleValue is intended to be read- only once the constructor has finished

Throws:

IllegalArgumentException - if the String value is illegal
