Package opendap.servers

This package contains the OPeNDAP Server classes.

See: Description

Interface Summary

Interface	Description
BoolFunction	Represents a server-side function, which evaluates to a boolean value.
BTFunction	Represents a server-side function, which evaluates to a BaseType.
Clause	Represents the common interface of the two types of clause used by the constraint expression (CE) parser: TopLevelClause and SubClause.
RelOps	The RelOps interface defines how each type responds to relational operators.
ServerArrayMethods	This interface extends the ArrayMethods for OPeNDAP types that extend DArray and DGrid classes.
ServerMethods	This interface defines the additional behaviors that Server side types need to support.
ServerSideFunction	Represents common interface of all server-side functions (SSF).
SubClause	Represents a sub-clause of the selection portion of a constraint expression.
TopLevelClause	Represents a top-level clause in the selection portion of a constraint expression (CE).

Class Summary

Class	Description
AbstractClause	Provides default implementations for the Clause interface methods.
BoolFunctionClause	Represents a clause which invokes a function that returns a boolean value.
BTFunctionClause	Represents a clause which invokes a function that returns a BaseType.
CEEvaluator	This class is used to parse and evaluate a constraint expression.
ClauseFactory	Represents a source of Clause objects for the constraint expression parser.
DereferenceClause	Represents a sub-clause that is a URL reference to remote data.
FunctionLibrary	Represents a library of available server-side functions for use in evaluating constraint expressions.
Operator	This class contains the code for performing relative operations (RelOps) on BaseTypes.
RelOpClause	Represents a clause which compares subclauses, using one of the relative operators supported by the Operator class.
SDArray	Holds a OPeNDAP Server Array value.
SDByte	Holds a OPeNDAP Server Byte value.
SDFloat32	Holds a OPeNDAP Server Float32 value.
SDFloat64	Holds a OPeNDAP Server Float64 value.
SDGrid	Holds a OPeNDAP Server Grid value.
SDInt16	Holds a OPeNDAP Server Int16 value.
SDInt32	Holds a OPeNDAP Server Int32 value.
SDList	Holds a OPeNDAP Server List value.
SDSequence	Holds a OPeNDAP Server Sequence value.
SDString	Holds a OPeNDAP Server String value.
SDStructure	Holds a OPeNDAP Server Structure value.
SDUInt16	Holds a OPeNDAP Server Unsigned Int16 value.
SDUInt32	Holds a OPeNDAP Server Unsigned Int32 value.
SDURL	Holds a OPeNDAP Server URL value.
ServerDDS	ServerDDS is a specialization of DDS for the server-side of OPeNDAP.
ValueClause	Represents a clause containing a simple value.

Exception Summary

Exception	Description
DAP2ServerSideException	DAP2 Exception for use by a server.
InvalidOperatorException	Thrown when a RelOp operation is called on two types for which it makes no sense to compre, such as attempting to ascertain is a String is less than a Float.
InvalidParameterException	Used to indicate that one of the passed parameters to a method is either the wrong type, is missing, or it's value is unacceptable.
RegExpException	Thrown by Operator.op when an attempt is made to parse a improperly formed regular expression.
SBHException	The Something Bad Happened (SBH) Exception.
SSFunctionException	Thrown when a Server Side Function (SSF) is used incorrectly.
WrongTypeException	Report a type-mismatch problem in the constraint expression.

Package opendap.servers Description

This package contains the OPeNDAP Server classes. These are used directly by specific implementations of OPeNDAP servers to provide the frame work for OPeNDAP server behaviours.
