Detailed Description

Internal definitions for Pajdeg.

Macro Definition Documentation

#define false   0

The false value.

#define PDAlloc	(		s,
			d,
			z
	)		PDAllocTyped(PDInstanceTypeUnset,s,d,z)

// IGNORE Allocate a new PDType object, with given size and deallocator.

Parameters

s	Size of object.
d	Dealloc method as a (*)(void*).
z	Whether the allocated block should be zeroed or not. If true, calloc is used to allocate the memory.

#define PDTYPE_ASSERT

(

ob

)

PDAssert(((PDTypeRef)ob - 1)->pdc == PDC)

A macro for asserting that an object is a proper PDType.

#define PDTYPE_PTR_LEN   4

The length of PDType, in pointers.

#define true   1

The truth value.

Typedef Documentation

typedef struct PDCryptoInstance* PDCryptoInstanceRef

Crypto instance for arrays/dicts.

typedef void(* PDInstanceCryptoExchange) (void *inst, PDCryptoInstanceRef ci, PDBool encrypted)

Crypto object exchange function signature.

Used to hand crypto information to arbitrary objects.

Function Documentation

void* PDAllocTyped	(	PDInstanceType	it,
		PDSize	size,
		void *	dealloc,
		PDBool	zeroed
	)

Allocate a new PDType object with a defined instance type, with given size and deallocator.

Parameters

it	Instance type.
size	Size of object.
dealloc	Dealloc method as a (*)(void*).
zeroed	Whether the allocated block should be zeroed or not. If true, calloc is used to allocate the memory.

void PDFlush

(

void

)

Flush autorelease pool.

void PDFlushUntil

(

void *

ob

)

Flush until the given object is encountered, or until the autorelease pool is exhausted. The object is released as well.

Parameters

ob	Termination marker for flush

PDObjectRef PDObjectCreate	(	PDInteger	obid,
		PDInteger	genid
	)

Create PDObjectRef with given ID and generation number.

Note

Normally this method is not called directly, but instead PDParserRef's PDParserCreateNewObject() is used.

Parameters

obid	Object ID
genid	Generation number

Returns

A detached object.

Variable Documentation

char* PDC

Identifier for PD type checking.

PDInstanceCryptoExchange PDInstanceCryptoExchanges[]

Crypto object exchange function array, matching up with all non-negative PDInstanceType entries.
