Detailed Description

Typedef Documentation

typedef unsigned int frepple::utils::hashtype

This is the datatype used for hashing an XML-element to a numeric value.

Definition at line 416 of file utils.h.

Enumeration Type Documentation

enum frepple::utils::Action

This type defines what operation we want to do with the entity.

Enumerator:

ADD	or A. Add an new entity, and report an error if the entity already exists.
CHANGE	or C. Change an existing entity, and report an error if the entity doesn't exist yet.
REMOVE	or D. Delete an entity, and report an error if the entity doesn't exist.
ADD_CHANGE	or AC. Change an entity or create a new one if it doesn't exist yet. This is the default action.

Definition at line 359 of file utils.h.

enum frepple::utils::mode

This type is used to define different ways of persisting an object.

Enumerator:

DEFAULT	Write the full object or a reference. If the object is nested more than one level deep a reference is written, otherwise the complete object is written. This mode is the one to be used when dumping all objects to be restored later. The other modes can dump too little or too much data. Eg: <MODEL NAME="POL" TYPE="a"><FIELD>value</FIELD></MODEL>
REFERENCE	Write only the key fields of the object. Eg: <MODEL NAME="POL" TYPE="a"/>
NOHEADER	Write the full object, but without a header line. This method is typically used when a subclass calls the write method of its parent class. Eg: <FIELD>value</FIELD></MODEL>
FULL	Write the full object, with all its fields and a header line. Eg: <MODEL NAME="POL" TYPE="a"><FIELD>value</FIELD></MODEL>

Definition at line 1877 of file utils.h.

enum frepple::utils::Signal

This type defines the types of callback events possible.

Enumerator:

SIG_ADD	Adding a new entity.
SIG_REMOVE	Deleting an entity.

Definition at line 394 of file utils.h.
