Member Function Documentation

simpleUsage()

void simpleUsage ( )

inlineprivate

Test:

demonstrate a simple usage scenario

Here is the call graph for this function:

use_and_drop()

void use_and_drop ( )

inlineprivate

Test:

verify claiming new and discarding old slots

Definition at line 85 of file extent-family-test.cpp.

iteration()

void iteration ( )

inlineprivate

Test:

verify access to the extents by iteration, thereby possibly claiming the next extents

Definition at line 112 of file extent-family-test.cpp.

reuseUnclean()

void reuseUnclean ( )

inlineprivate

Test:

verify that neither constructors nor destructors are invoked automatically when discarding or re-using extents.

Definition at line 162 of file extent-family-test.cpp.

References ExtentFamily< T, siz >::openNew(), and lib::rani().

Here is the call graph for this function:

wrapAround()

void wrapAround ( )

inlineprivate

Test:

verify in detail how iteration wraps around to also reuse previously dropped extents, possibly rearranging the internal management-vector to allow growing new extents at the end.

• existing allocations are re-used cyclically
• this may lead to a »wrapped« internal state
• necessitating to expand allocations in the middle
• yet all existing Extent addresses remain stable
