Public Member Functions
NAMESPACE_OSGEO_FDO_FILTER::Filter *	Combine (System::String *leftFilter, NAMESPACE_OSGEO_FDO_FILTER::BinaryLogicalOperations operation, System::String *rightFilter)
	Static operation that combines two filters using the specified binary logical operation.
NAMESPACE_OSGEO_FDO_FILTER::Filter *	Combine (NAMESPACE_OSGEO_FDO_FILTER::Filter *leftFilter, NAMESPACE_OSGEO_FDO_FILTER::BinaryLogicalOperations operation, System::String *rightFilter)
	Static operation that combines two filters using the specified binary logical operation.
NAMESPACE_OSGEO_FDO_FILTER::Filter *	Combine (System::String *leftFilter, NAMESPACE_OSGEO_FDO_FILTER::BinaryLogicalOperations operation, NAMESPACE_OSGEO_FDO_FILTER::Filter *rightFilter)
	Static operation that combines two filters using the specified binary logical operation.
NAMESPACE_OSGEO_FDO_FILTER::Filter *	Combine (NAMESPACE_OSGEO_FDO_FILTER::Filter *leftFilter, NAMESPACE_OSGEO_FDO_FILTER::BinaryLogicalOperations operation, NAMESPACE_OSGEO_FDO_FILTER::Filter *rightFilter)
	Static operation that combines two filters using the specified binary logical operation.
	Filter (System::IntPtr unmanaged, System::Boolean autoDelete)
System::Void	Process (NAMESPACE_OSGEO_FDO_FILTER::IFilterProcessor *processor)
	Abstract operation that takes an FdoIFilterProcessor as an argument. Concrete filter subclasses must override this method and pass themselves as an argument to the appropriate filter processor operation.
System::String *	ToString ()
	Converts the filter expression to its well defined text representation.
Static Public Member Functions
static NAMESPACE_OSGEO_FDO_FILTER::Filter *	Parse (System::String *filterText)
	Static operation that parses the well defined text representation and returns a Filter instance.
Protected Member Functions
System::Void	ReleaseUnmanagedObject ()
