name	The name of this new attribute.
doubleArray	The underlying storage for the array.
length	The number of items in the array.

Member Function Documentation

OkToWrite()

virtual bool OkToWrite ( ) const

overridevirtual

This SHOULD be overriden by any derived objects that may not be ready to write at any point. The reason for this is the data is often written "NAME: VALUE". If Value is not available, we don't want to write "NAME: " first, so before writing "NAME: ", OkToWrite() can be called to see if it will have a valid value.

Returns

True if this object is ready to have its WriteValue() called.

Reimplemented from DistiAttributeBase.

ReadValue()

virtual std::istream & ReadValue ( std::istream &  instr )

overridevirtual

Pure virtual because this is specific to the data type to be contained. This should be overridden to read the data from the stream. The value read could be encoded for being read from a file as a single string, or have its own special encoding specific to its underlying type. In the case of attribute strings, this will be the GLS file encoded value. The user is responsible for encoding the value themselves, or using WriteValue which should perform encoding to maintain symmetry.

Parameters

instr

The stream to read from.

Returns

The input stream in its current state.

Implements DistiAttributeBase.

WriteValue()

virtual std::ostream & WriteValue ( std::ostream &  outstr )

overridevirtual

Pure virtual because this is specific to the data type to be contained. This should be overridden to write the data to the stream. The value written could be encoded for writing to a file as a single string, or have its own special encoding specific to its underlying type. In the case of attribute strings, this will be the GLS file encoded value. The user is responsible for decoding the value themselves, or using ReadValue which should perform decoding to maintain symmetry.

Parameters

outstr

The stream to write to.

Returns

The output stream in its current state.

Implements DistiAttributeBase.
