Detailed Description

Encapsulates a MFFloat.


Constructor & Destructor Documentation

MFFloat size_t    length = 0,
float const *    values = 0
throw (std::bad_alloc) [explicit]
 

Construct from a float array.

Parameters:
length the number of floats in the array
values a pointer to a float array

~MFFloat   throw () [virtual]
 

Destructor.


Member Function Documentation

void addElement float    value throw (std::bad_alloc)
 

Add an element to the end of the sequence.

Parameters:
value the value to add.
Exceptions:
std::bad_alloc if memory allocation fails.

FieldValue & assign const FieldValue   value throw (std::bad_cast, std::bad_alloc) [virtual]
 

Virtual assignment.

Returns:
a reference to the object.
Exceptions:
std::bad_cast if value is not an MFFloat object.
std::bad_alloc if memory allocation fails.

Implements FieldValue.

std::auto_ptr< FieldValue > clone   const throw (std::bad_alloc) [virtual]
 

Virtual copy constructor.

Returns:
a pointer to a copy of the object.
Exceptions:
std::bad_alloc if memory allocation fails.

Implements FieldValue.

const float & getElement size_t    index const throw ()
 

Get element.

Parameters:
index 

size_t getLength   const throw ()
 

Get the length.

Returns:
the number of float values

void insertElement size_t    index,
float    value
throw (std::bad_alloc)
 

Insert an element into the sequence.

Parameters:
index the index where the new value should be inserted.
value a float value.
Exceptions:
std::bad_alloc if memory allocation fails.
Precondition:
index is a valid index.

void print std::ostream &    out const [private, virtual]
 

Print to an output stream.

Parameters:
out an output stream.

Implements FieldValue.

void removeElement size_t    index throw ()
 

Remove an element from the sequence.

Parameters:
index the index of the value to remove.
Precondition:
index is a valid index.

void setElement size_t    index,
float    value
throw ()
 

Set element.

Parameters:
index 
value 

void setLength size_t    length throw (std::bad_alloc)
 

Set the length.

If the new length is greater than the current length, the additional values are initialized to the default (0.0). If the new length is less than the current length, the array is truncated.

Parameters:
length new length
Exceptions:
std::bad_alloc if memory allocation fails.

FieldValue::Type type   const throw () [virtual]
 

Get the type identifier for the class.

Returns:
the type identifer for the class.

Implements FieldValue.
