Detailed Description

This class holds the bound keyword set for a given Bayonne style script interpreter.

Application specific dialects are created by deriving a application specific version of ScriptCommand which then binds application specific keywords and associated methods in an application derived ScriptInterp which are typecast to (scriptmethod_t).

Author: David Sugar dyfet.nosp@m.@ost.nosp@m.el.co.nosp@m.m Bayonne script keyword binding tables and compiler constants.

void Keydata::load ( const char * keypath )

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.

Parameters

keypath (filepath/section)

void Keydata::load ( Define * pairs )

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.

Parameters

pairs list of NULL terminated default keyword/value pairs.

void ost::ScriptCommand::load ( Script::Define * keywords )

protected

Load a set of keywords into the system keyword table.

This provides a convenient method of initializing and adding to the keyword indexes.

Parameters

keywords defined pair entries to load.

void Keydata::loadFile	(	const char *	filepath,
		const char *	keys = `NULL`,
		const char *	pre = `NULL`
	)

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.

Parameters

filepath	to load from
keys	section to parse from, or NULL to parse from head
pre	optional key prefix

void Keydata::loadPrefix	(	const char *	prefix,
		const char *	keypath
	)

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.

Parameters

prefix
keypath	(filepath/section)

void Mutex::nameMutex ( const char * name )

inlineinherited

Enable setting of mutex name for deadlock debug.
