|
protectedvirtualinherited |
Allocate memory from either the currently active page, or allocate a new page for the object.
size | size of memory to allocate. |
Reimplemented in SharedMemPager.
|
protectedinherited |
Allocate a string from the memory pager pool and copy the string inti it's new memory area.
This checks only the last active page for available space before allocating a new page.

Clear all values associated with a given keyword.
This does not de-allocate the keyword from memory, however.
|
staticinherited |

virtualinherited |
Fast branch linkback code.
Reimplemented in ost::ScriptCompiler.
|
protectedvirtualinherited |
Allocate first workspace from paged memory.
This method scans all currently allocated blocks for available space before adding new pages and hence is both slower and more efficient.
size | size of memory to allocate. |
Reimplemented in SharedMemPager.
|
protectedinherited |
Allocate a string from the memory pager pool and copy the string into it's new memory area.
This method allocates memory by first searching for an available page, and then allocating a new page if no space is found.
str | string to allocate and copy into paged memory pool. |

inherited |
Load additional key values into the currrent object from the specfied config source (a config file/section pair).
These values will overlay the current keywords when matches are found. This can be used typically in a derived config object class constructor to first load a /etc
section, and then load a matching user specific entry from ~/.
to override default system values with user specific keyword values.
keypath | (filepath/section) |
|
inherited |
Load default keywords into the current object.
This only loads keyword entries which have not already been defined to reduce memory usage. This form of Load is also commonly used in the constructor of a derived Keydata class.
pairs | list of NULL terminated default keyword/value pairs. |
|
inherited |
Used by a derived constructor to load an initialization list.
ilist | initialization list of symbol pairs to load. |
|
inherited |
Load additional keys into the current object using a real filename that is directly passed rather than a computed key path.
This also uses a [keys] section as passed to the object.
filepath | to load from |
keys | section to parse from, or NULL to parse from head |
pre | optional key prefix |
|
inherited |
Load additional key values into the currrent object from the specfied config source (a config file/section pair).
These values will overlay the current keywords when matches are found. This can be used typically in a derived config object class constructor to first load a /etc
section, and then load a matching user specific entry from ~/.
to override default system values with user specific keyword values. This varient puts a prefix in front of the key name.

Unlink the keydata object from the cache file stream.
This should be used if you plan to keepa Keydata object after it is loaded once all keydata objects have been loaded, otherwise the cfgFile stream will remain open. You can also use endKeydata().
