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

Constructor & Destructor Documentation

CORBA_TypeCode::CORBA_TypeCode ( CORBA::TCKind kind )

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

CORBA_TypeCode::CORBA_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

Member Data Documentation

CORBA::TypeCode_ptr CORBA_TypeCode::_tc_BadKind [static]

CORBA::TypeCode_ptr CORBA_TypeCode::_tc_Bounds [static]

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.

CORBA::Boolean CORBA_TypeCode::orb_owns_ [private]

TAO's approach differs from the SunSoft IIOP. Constant typecodes are owned by the ORB and get freed only when the ORB dies.

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.

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_
