Member Function Documentation

static vtkXMLUtilities* vtkXMLUtilities::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkXMLUtilities::GetClassName ( ) [virtual]

Reimplemented from vtkObject.

static int vtkXMLUtilities::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkXMLUtilities::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkXMLUtilities* vtkXMLUtilities::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkObject.

static void vtkXMLUtilities::EncodeString	(	const char *	input,
		int	input_encoding,
		ostream &	output,
		int	output_encoding,
		int	special_entities = `0`
	)			`[static]`

Encode a string from one format to another (see VTK_ENCODING_... constants). If special_entites is true, convert some characters to their corresponding character entities.

static void vtkXMLUtilities::CollateAttributes	(	vtkXMLDataElement *	,
		ostream &	,
		const char *	sep = `0`
	)			`[static]`

Collate a vtkXMLDataElement's attributes to a stream as a series of name="value" pairs (the separator between each pair can be specified, if not, it defaults to a space). Note that the resulting character-encoding will be UTF-8 (we assume that this function is used to create XML files/streams).

static void vtkXMLUtilities::FlattenElement	(	vtkXMLDataElement *	,
		ostream &	,
		vtkIndent *	indent = `0`,
		int	indent_attributes = `1`
	)			`[static]`

Flatten a vtkXMLDataElement to a stream, i.e. output a textual stream corresponding to that XML element, its attributes and its nested elements. If 'indent' is not NULL, it is used to indent the whole tree. If 'indent' is not NULL and 'indent_attributes' is true, attributes will be indented as well. Note that the resulting character-encoding will be UTF-8 (we assume that this function is used to create XML files/streams).

static int vtkXMLUtilities::WriteElementToFile	(	vtkXMLDataElement *	,
		const char *	filename,
		vtkIndent *	indent = `0`
	)			`[static]`

Write a vtkXMLDataElement to a file (in a flattened textual form) Note that the resulting character-encoding will be UTF-8. Return 1 on success, 0 otherwise.

static vtkXMLDataElement* vtkXMLUtilities::ReadElementFromStream	(	istream &	,
		int	encoding = `VTK_ENCODING_NONE`
	)			`[static]`

Read a vtkXMLDataElement from a stream, string or file. The 'encoding' parameter will be used to set the internal encoding of the attributes of the data elements created by those functions (conversion from the XML stream encoding to that new encoding will be performed automatically). If set to VTK_ENCODING_NONE, the encoding won't be changed and will default to the default vtkXMLDataElement encoding. Return the root element on success, NULL otherwise. Note that you have to call Delete() on the element returned by that function to ensure it is freed properly. BTX

static vtkXMLDataElement* vtkXMLUtilities::ReadElementFromString	(	const char *	str,
		int	encoding = `VTK_ENCODING_NONE`
	)			`[static]`

Read a vtkXMLDataElement from a stream, string or file. The 'encoding' parameter will be used to set the internal encoding of the attributes of the data elements created by those functions (conversion from the XML stream encoding to that new encoding will be performed automatically). If set to VTK_ENCODING_NONE, the encoding won't be changed and will default to the default vtkXMLDataElement encoding. Return the root element on success, NULL otherwise. Note that you have to call Delete() on the element returned by that function to ensure it is freed properly. BTX

static vtkXMLDataElement* vtkXMLUtilities::ReadElementFromFile	(	const char *	filename,
		int	encoding = `VTK_ENCODING_NONE`
	)			`[static]`

Read a vtkXMLDataElement from a stream, string or file. The 'encoding' parameter will be used to set the internal encoding of the attributes of the data elements created by those functions (conversion from the XML stream encoding to that new encoding will be performed automatically). If set to VTK_ENCODING_NONE, the encoding won't be changed and will default to the default vtkXMLDataElement encoding. Return the root element on success, NULL otherwise. Note that you have to call Delete() on the element returned by that function to ensure it is freed properly. BTX

static void vtkXMLUtilities::ReadElementFromAttributeArray	(	vtkXMLDataElement *	element,
		const char **	atts,
		int	encoding
	)			`[static]`

Sets attributes of an element from an array of encoded attributes. The 'encoding' parameter will be used to set the internal encoding of the attributes of the data elements created by those functions (conversion from the XML stream encoding to that new encoding will be performed automatically). If set to VTK_ENCODING_NONE, the encoding won't be changed and will default to the default vtkXMLDataElement encoding.

static int vtkXMLUtilities::FindSimilarElements	(	vtkXMLDataElement *	elem,
		vtkXMLDataElement *	tree,
		vtkXMLDataElement ***	results
	)			`[static]`

Find all elements in 'tree' that are similar to 'elem' (using the vtkXMLDataElement::IsEqualTo() predicate). Return the number of elements found and store those elements in 'results' (automatically allocated). Warning: the results do not include 'elem' if it was found in the tree ; do not forget to deallocate 'results' if something was found. BTX

static void vtkXMLUtilities::FactorElements ( vtkXMLDataElement * tree ) [static]

Factor and unfactor a tree. This operation looks for duplicate elements in the tree, and replace them with references to a pool of elements. Unfactoring a non-factored element is harmless.

static void vtkXMLUtilities::UnFactorElements ( vtkXMLDataElement * tree ) [static]

Factor and unfactor a tree. This operation looks for duplicate elements in the tree, and replace them with references to a pool of elements. Unfactoring a non-factored element is harmless.

static int vtkXMLUtilities::FactorElementsInternal	(	vtkXMLDataElement *	tree,
		vtkXMLDataElement *	root,
		vtkXMLDataElement *	pool
	)			`[static, protected]`

static int vtkXMLUtilities::UnFactorElementsInternal	(	vtkXMLDataElement *	tree,
		vtkXMLDataElement *	pool
	)			`[static, protected]`
