Function Documentation

ElementPtr isc::data::copy	(	ConstElementPtr	from,
		int	level = `100`
	)

Copy the data up to a nesting level.

The copy is a deep copy so nothing is shared if it is not under the given nesting level.

Parameters

from	the pointer to the element to copy
level	nesting level (default is 100, 0 means shallow copy, negative means outbound and perhaps looping forever).

Returns: a pointer to a fresh copy

Exceptions

raises a BadValue is a null pointer occurs.

bool isc::data::isEquivalent	(	ConstElementPtr	a,
		ConstElementPtr	b
	)

Compares the data with other using unordered lists.

This comparison function handles lists (JSON arrays) as unordered multi sets (multi means an item can occurs more than once as soon as it occurs the same number of times).

bool isc::data::isNull ( ConstElementPtr p )

Checks whether the given ElementPtr is a NULL pointer.

Parameters

p	The ElementPtr to check

Returns: true if it is NULL, false if not.

void isc::data::merge	(	ElementPtr	element,
		ConstElementPtr	other
	)

Merges the data from other into element.

(on the first level). Both elements must be MapElements. Every string,value pair in other is copied into element (the ElementPtr of value is copied, this is not a new object) Unless the value is a NullElement, in which case the key is removed from element, rather than setting the value to the given NullElement. This way, we can remove values from for instance maps with configuration data (which would then result in reverting back to the default). Raises a TypeError if either ElementPtr is not a MapElement

Here is the call graph for this function:

std::ostream & isc::data::operator<<	(	std::ostream &	out,
		const Element::Position &	pos
	)

Insert Element::Position as a string into stream.

This operator converts the Element::Position into a string and inserts it into the output stream out.

Parameters

out	A `std::ostream` object on which the insertion operation is performed.
pos	The `Element::Position` structure to insert.

Returns: A reference to the same std::ostream object referenced by parameter out after the insertion operation.

Here is the call graph for this function:

std::ostream & isc::data::operator<<	(	std::ostream &	os,
		const ServerTag &	server_tag
	)

Insert the ServerTag as a string into stream.

Parameters

os	stream to insert server tag into.
server_tag	server tag to be converted to text and inserted into a stream.

Returns: Reference to the stream object with inserted server tag.

Definition at line 47 of file server_tag.cc.

Here is the call graph for this function:

std::ostream & isc::data::operator<<	(	std::ostream &	out,
		const Element &	e
	)

Insert the Element as a string into stream.

This method converts the ElementPtr into a string with Element::str() and inserts it into the output stream out.

This function overloads the global operator<< to behave as described in ostream::operator<< but applied to ElementPtr objects.

Parameters

out	A `std::ostream` object on which the insertion operation is performed.
e	The `ElementPtr` object to insert.

Returns: A reference to the same std::ostream object referenced by parameter out after the insertion operation.

Here is the call graph for this function:

void isc::data::prettyPrint	(	ConstElementPtr	element,
		std::ostream &	out,
		unsigned	indent = `0`,
		unsigned	step = `2`
	)

Pretty prints the data into stream.

This operator converts the ConstElementPtr into a string and inserts it into the output stream out with an initial indentation indent and add at each level step spaces. For maps if there is a comment property it is printed first.

Parameters

element	A `ConstElementPtr` to pretty print
out	A `std::ostream` on which the print operation is performed
indent	An initial number of spaces to add each new line
step	A number of spaces to add to indentation at a new level

std::string isc::data::prettyPrint	(	ConstElementPtr	element,

Pretty prints the data into string.

This operator converts the ConstElementPtr into a string with an initial indentation indent and add at each level step spaces. For maps if there is a comment property it is printed first.

Parameters

element	A `ConstElementPtr` to pretty print
indent	An initial number of spaces to add each new line
step	A number of spaces to add to indentation at a new level

Returns: a string where element was pretty printed

void isc::data::removeIdentical	(	ElementPtr	a,
		ConstElementPtr	b
	)

Remove all values from the first ElementPtr that are equal in the second.
