PD_Layer.PDNumTree (PDFL)

	Typedef
	PDNumTree An object that points to the root node of a number tree inside a PDF file. A number tree is used to map integers to arbitrary Cos objects just as a Cos dictionary is used to map Cos names to Cos objects. However, a number tree can have many more entries than a Cos dictionary can.

	Method
	void PDNumTreeEnum(PDNumTree theTree, CosObjEnumProc proc, void* clientData) Enumerates the entries in the tree.
	ASBool PDNumTreeEqual(PDNumTree tree1, PDNumTree tree2) Compares two number trees to determine if they are the same object.
	PDNumTree PDNumTreeFromCosObj(CosObj obj) Creates a type cast of the CosObj to a number tree.
	ASBool PDNumTreeGet(PDNumTree theTree, ASInt32 key, CosObj* value) Retrieves an object from the number tree.
	CosObj PDNumTreeGetCosObj(PDNumTree theTree) Creates a type cast of the number tree to a CosObj.
	ASBool PDNumTreeIsValid(PDNumTree theTree) Validates whether a PDNumTree is a CosDict Cos object.
	PDNumTree PDNumTreeNew(PDDoc pdDoc) Creates a new number tree in the document.
	void PDNumTreeNumAdded(PDNumTree numTree, ASInt32 key, CosObj value, void* clientData) An entry was added to a name tree.
	void PDNumTreeNumRemoved(PDNumTree numTree, ASInt32 key, void* clientData) An entry was removed from a name tree.
	void PDNumTreePut(PDNumTree theTree, ASInt32 key, CosObj value) Puts a new entry in the number tree. If an entry with this number is already in the tree, it is replaced.
	void PDNumTreeRemove(PDNumTree theTree, ASInt32 key) Removes the specified object from the tree. It does nothing if no object with that number exists.

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax

typedef OPAQUE_64_BITS PDNumTree;

An object that points to the root node of a number tree inside a PDF file. A number tree is used to map integers to arbitrary Cos objects just as a Cos dictionary is used to map Cos names to Cos objects. However, a number tree can have many more entries than a Cos dictionary can.

Method Detail

PDNumTreeEnum

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





void PDNumTreeEnum(PDNumTree theTree, CosObjEnumProc proc, void* clientData)

Enumerates the entries in the tree.

Parameters

	`theTree` —	IN/OUT A number tree.

	`proc` —	IN/OUT A procedure to call once for each number destination pair in `theTree`.

	`clientData` —	IN/OUT Data used by the enumeration procedure. `clientData` is passed to the enumeration procedure proc each time a number tree is encountered.
