Detailed Description

Interpreter status.

Invariant

Singleton.

pimpltime_ is not null

Constructor & Destructor Documentation

~Interpreter()

Interpreter::~Interpreter ( )

virtual

Dtor.

It's virtual, because DbC has a virtual bool invariant() member.

Member Function Documentation

get()

static auto Interpreter::get ( )

inlinestatic

Get the singleton pointer.

Postcondition

return value != nullptr

getClockStart()

__int128 Interpreter::getClockStart

(

)

const

Getter for clock start.

Hides implementation with a struct PimplTime.

getLine()

bool Interpreter::getLine

(

std::string &

p_line

)

const

Wrapper around getline to hide input stream.

Precondition

linesource != nullptr

invariant()

bool Interpreter::invariant ( ) const

inlineoverrideprotectedvirtualnoexcept

Checks class invariants.

Returns

bool ... Indicates whether the class invariants are maintained.

Reimplemented from DbC.

ksnline()

void Interpreter::ksnline ( std::string &  p_line, Context &  k  )

static

Processes one line of the KSN-format input.

Executable names outside of procedures and '{', '}' are pushed onto the execution stack. Everything else is pushed onto the operand stack.

shutdown()

void Interpreter::shutdown

(

)

Shut down.

Closes the line source.

snap()

void Interpreter::snap

(

)

Snapshot of system state to Interpreter-cout.

Includes statistics().

statistics()

void Interpreter::statistics

(

bool

p_force = false

)

Dumps statistical data.

Dumps it only if (i) there are open memory allocations or (ii) the verbose mode is set or (iii) p_force is true

Member Data Documentation

compile_

bool Interpreter::compile_ = false

private

Interpreter Property.

Controls if the operator bind includes compile features.

compileiterations_

size_t Interpreter::compileiterations_ = 10

private

Interpreter Property.

Maximum compile iterations even if there are possible optimizations.

cout_

std::ostream Interpreter::cout_ { std::cout.rdbuf() }

private

Interpreter Property.

Our out ostream. Prepares for rerouting.

curctx_

Context* Interpreter::curctx_ {}

private

Access to the current Context.

Interpreter ist not the owner.

linesource_

LineSource* Interpreter::linesource_ {}

private

Read from cin or from file.

Interpreter is the owner. Interpreter allocates memory on demand.
