Detailed Description

The ProgramControl class provides safe information about a Qore program.

Restrictions:: MUST HAVE: Qore::PO_ALLOW_DEBUGGER

The object is never instantiated in script but returned by a API function. The class provides only safe data non breaking security model.

See also: Program

Since: Qore 0.8.13

Member Function Documentation

◆ constructor()

Qore::ProgramControl::constructor ( )

Throws an exception to prevent objects of this class being created from script.

Exceptions

PROGRAM-CREATE-ERROR copying ProgramControl objects is currently unsupported

◆ copy()

Qore::ProgramControl::copy ( )

Throws an exception to prevent objects of this class from being copied.

Exceptions

PROGRAM-COPY-ERROR copying Program objects is currently unsupported

◆ existsFunction()

bool Qore::ProgramControl::existsFunction ( string name )

Checks if a user function exists in the program object.

Code Flags:: RET_VALUE_ONLY

see Qore::Program::existsFunction "Program::existsFunction()"

◆ findFunctionStatementId()

int Qore::ProgramControl::findFunctionStatementId	(	string	function,
		*list	params
	)

Find the first statement for function entry point.

Parameters

function	name
params	param types to resolve particular variant

See also: ProgramControl::findStatementId()

◆ findFunctionVariants()

list<hash<auto> > Qore::ProgramControl::findFunctionVariants ( string function )

finds all variants of a function or class method and returns a list of the results

Parameters

function the function or class method name; may also be namespace-justified

Returns

a list of hashes or nothing if the name cannot be resolved; when matched, each hash element has the following keys:

desc: a string description of the call which includes the name and the full text call signature
params: a list object that gives the params in a format that can be used by findFunctionStatementId

◆ findStatementId()

int Qore::ProgramControl::findStatementId	(	string	file,
		int	line
	)

Find statement related to position in file.

Parameters

file	name where is looking for. Searching is done in three steps, in the first one is looking for full name match, in the second is looking for label full match (if exists) and in the third for end suffix match. File can by empty if program contains only one file. Beware of label formating, see Qore::Program::parse
line	to find statement. In case of multiple statements of line the first one is found
