Member Function Documentation

virtual bool getBoolean ( bool  fDefault = false  )  const [pure virtual]

Get the value as a bool.

If the internal value cannot be translated into a bool, the supplied default value is returned.

Parameters:
fDefault the default return value
Returns:
the value as a bool or the default value

virtual void setBoolean ( bool  fValue  )  [pure virtual]

Set the value as a bool.

Parameters:
fValue a new value of type bool

virtual int32_t getInt32 ( int32_t  nDefault = 0  )  const [pure virtual]

Get the value as an integer.

If the internal value cannot be translated into int32_t, the supplied default value is returned.

Parameters:
nDefault the default return value
Returns:
the value as int32_t or the default value

virtual void setInt32 ( int32_t  nValue  )  [pure virtual]

Set the integer value.

Parameters:
nValue a new value of type int32_t

virtual String::View getString ( String::View  vsDefault = ""  )  const [pure virtual]

Get the value as a String.

If the internal value cannot be translated into a String, the supplied default value is returned.

Parameters:
vsDefault the default return value
Returns:
the value as a String or the default value

virtual void setString ( String::View  vsValue  )  [pure virtual]

Set the String value.

Parameters:
vsValue a new value of type String

virtual Object::View getValue (  )  const [pure virtual]

Get the value as an Object.

The following types are supported:

It is always legal for an implementation to return the value as a String.

Returns:
the value as an Object or NULL if the XmlValue does not have a value; attributes never have a NULL value

virtual TypedHandle<XmlElement> getParent (  )  [pure virtual]

Get the parent element of this value.

Returns:
the parent element, or NULL if this value has no parent

virtual TypedHandle<const XmlElement> getParent (  )  const [pure virtual]

Get the parent element of this value as a view.

Returns:
the parent element, or NULL if this value has no parent

virtual void setParent ( TypedHandle< XmlElement hElement  )  [pure virtual]

Set the parent element of this value.

Once set, the parent cannot be reset.

Parameters:
hElement the parent element
Exceptions:
coherence::lang::IllegalArgumentException if the specified parent is NULL
coherence::lang::IllegalStateException if the parent is already set

virtual bool isEmpty (  )  const [pure virtual]

Determine if the value is empty.

Returns:
true if the value is empty, false otherwise

virtual bool isAttribute (  )  const [pure virtual]

Determine if this value is an element attribute.

Returns:
true if this value is an element attribute, false otherwise

virtual bool isContent (  )  const [pure virtual]

Determine if this value is an element's content.

Returns:
true if this value is an element's content, false otherwise

virtual String::View formatValue (  )  const [pure virtual]

Format the value as XML.

Returns:
the XML formatted string

__attribute__ ( (always_inline)   )  [inline]

Write the value as XML.

Parameters:
out an std::ostream to write to

Reimplemented in XmlElement.
