bool doConversion ( ) const Get whether conversions will be performed to match the memory type of buffer. The API user must explicitly request conversion between basic representation groups in memory and on the disk. The four basic representation groups are: integer, boolean, floating point, and string. There is no distinction between integer and boolean groups on the disk (they both use IntegerNode). A explicit request for conversion between single and double precision floating point representations is not required. The most useful conversion is between integer and floating point representation groups. Conversion from integer to floating point representations cannot result in an overflow, and is usually loss-less (except for extremely large integers). Conversion from floating point to integer representations can result in an overflow, and can be lossy. Conversion between any of the integer, boolean, and floating point representation groups is supported. No conversion from the string to any other representation group is possible. Missing or unsupported conversions are detected when the first transfer is attempted (i.e. not when the CompressedVectorReader or CompressedVectorWriter is created). Postcondition: No visible state is modified. Returns: true if conversions will be performed to match the memory type of buffer.
