Detailed Description

The FdoFilter abstract class is a base class for condition and operator classes that can occur in a filter expression tree. The FdoFilter class contains operations for converting between the text and expression tree representation of a filter.

Public Member Functions

virtual FDO_API void Process (FdoIFilterProcessor *p)=0
 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.
FDO_API FdoString * ToString ()
 Converts the filter expression to its well defined text representation.
virtual FdoString * ToStringInternal (FdoIdentifierCollection *pIdCol)=0
 This is an internal method. It returns the well defined text representation of the filter.

Static Public Member Functions

static FDO_API FdoFilter * Combine (FdoString *lhs, FdoBinaryLogicalOperations operation, FdoString *rhs)
 Static operation that combines two filters using the specified binary logical operation.
static FDO_API FdoFilter * Combine (FdoFilter *lhs, FdoBinaryLogicalOperations operation, FdoString *rhs)
 Static operation that combines two filters using the specified binary logical operation.
static FDO_API FdoFilter * Combine (FdoString *lhs, FdoBinaryLogicalOperations operation, FdoFilter *rhs)
 Static operation that combines two filters using the specified binary logical operation.
static FDO_API FdoFilter * Combine (FdoFilter *lhs, FdoBinaryLogicalOperations operation, FdoFilter *rhs)
 Static operation that combines two filters using the specified binary logical operation.
static FDO_API FdoFilter * Parse (FdoString *filterText)
 Static operation that parses the well defined text representation and returns a Filter instance.
