codeContextGist()

ScopedId FadingCodeContext::codeContextGist ( ) const

inlineoverridevirtual

Returns

a small, permanent ID of the current context gists persist forever and are suitable for passing to other SMP workers

Implements CodeContext.

Definition at line 18 of file CodeContext.cc.

References gist.

Current()

const CodeContext::Pointer & CodeContext::Current ( )

staticinherited

Returns

the known global context or, to indicate unknown context, nil

Definition at line 33 of file CodeContext.cc.

Entering()

void CodeContext::Entering ( const Pointer &  codeCtx )

staticprivateinherited

Switches the current context to the given known context. Improves debugging output by replacing omni-directional "Reset" with directional "Entering".

ForgetCurrent()

void CodeContext::ForgetCurrent ( )

staticprivateinherited

Forgets the current known context, possibly triggering its destruction. Preserves the gist of the being-forgotten context during its destruction. Knows nothing about the next context – the caller must set it.

Leaving()

void CodeContext::Leaving ( )

staticprivateinherited

Forgets the current known context. Improves debugging output by replacing omni-directional "Reset" with directional "Leaving".
