Detailed Description

The CORBA TypeCode class. It maintains the in-memory representation of any OMG CORBA IDL data type.

Implements the CORBA::TypeCode interface specified by CORBA 2.0 spec. Typecodes essentially consist of just the CDR octets that get marshaled and unmarshaled, and this code knows how to parse those octets and answer questions CORBA's TypeCode APIs require.

A TypeCode describes data. This one's as thin a wrapper around CDR octet sequences as is practical. There are guesses here about how the OMG C++ mapping and CORBA 2.0 IfR specification will interact.

Note:: Use TypeCode_ptr, except in code (e.g. output of and OMG-IDL / compiler) that needs to create typecodes from their octet-sequence encodings.

Note:: This isn't well tuned performance-wise. Given how much is variable (byte order, alignment) it's clear tuning has its limits with respect to CDR bytecode interpretation.

Note:: (THREADING) Typecodes are readonly data structures, and the only mutual exclusion relates to reference counting and construction.

Constructor & Destructor Documentation

CORBA::TypeCode::TypeCode ( CORBA::TCKind kind )

This constructor is used only for built-in TypeCode constants, with no parameters.

CORBA::TypeCode::TypeCode ( CORBA::TCKind kind,

size_t length,

const char * buffer,

CORBA::Boolean orb_owns_tc,

CORBA::ULong size,

CORBA::TypeCode_ptr parent = 0

)

This constructor is used both for typecode constants and for heap-allocated TypeCodes. The two are distinguished by the orb_owns_tc flag passed in by the creator.
For simple param lists with a single numeric parameter, only 'length' matters.
For complex param lists, or simple param lists for which the parameter is a string or typecode, length _and_ buffer matter.
For typecodes that are precomputed from the encapsulation stream of the parent, even the "parent" argument matters because this implies that all children will share the octet buffers of its parent

const char* CORBA::TypeCode::buffer_

the encapsulated stream

CORBA::Long CORBA::TypeCode::byte_order_

The byte order in the encapsulated stream.

CORBA::Long CORBA::TypeCode::kind_

the TypeCode kind

size_t CORBA::TypeCode::length_

length of the encapsulated stream

char* CORBA::TypeCode::non_aligned_buffer_ [private]

Original buffer that may possibly be non-aligned. We still need a handle to the allocated memory so that all of it can be freed by the destructor.

OFFSET_MAP* CORBA::TypeCode::offset_map_ [private]

CORBA::Boolean CORBA::TypeCode::orb_owns_ [private]

If "orb_owns" is false, the value is a not a constant typecode with both the typecode and the buffer allocated (typically, this will be created by the IDL compiler generated code)

CORBA::TypeCode_ptr CORBA::TypeCode::parent_

Indirected typecodes share "buffer" with a parent, and hold a reference to that parent to ensure its memory is not freed inappropriately.

TAO::TC_Private_State* CORBA::TypeCode::private_state_ [private]

maintains precomputed state. We need a separate class that maintains the precomputed state since most of the TypeCode class operations keep the state of the object constant. However, for the purpose of precomputation, we need to update the state. We cannot update state directly in the TypeCode class as that defeats the constness. However, we can keep an object in our typecode class that remains constant, but we can update its state.

CORBA::ULong CORBA::TypeCode::refcount_ [private]

if refcount reaches 0, free this typecode

TAO_SYNCH_MUTEX CORBA::TypeCode::refcount_lock_ [private]

Protect the reference count, this is OK because we do no duplicates or releases on the critical path.

const char* CORBA::TypeCode::root_tc_base_

base of the topmost level typecode. Applicable only if I have any parents, else it is the same as tc_base. This helps in case we have indirections and we need to traverse beyond encapsulation boundaries.

const char* CORBA::TypeCode::tc_base_

my typecode base. Notice that the buffer_ member points to my encapsulation. However, for indirected typecodes, the offsets will point to my tk_kind field which should be pointed to be tc_base_.
