Contains current, new, old and default values for the column. Validates data passed in and generates error messages if needed

Definition at line 132 of file Record.h.

Constructor & Destructor Documentation

Record::rColumn::rColumn ( dbMeta::mColumn * pmCol )

Build a coulmn object for this record and link it to the static description.

Parameters:

mCol reference to the static data for this column

Definition at line 179 of file Record.cpp.

Record::rColumn::~rColumn ( ) [virtual]

Definition at line 185 of file Record.cpp.

Member Function Documentation

void Record::rColumn::clearError ( )

Reset the error field.

Definition at line 341 of file Record.cpp.

void Record::rColumn::copyCurrent ( )

Copy current database value into new and old field.
This is used before and update to make sure fields that were not specificied are not changed. If a field isn't specificed it's current value will be written back. This allows a single update statement to be cached.
Definition at line 332 of file Record.cpp.

const nsAReadableString & Record::rColumn::getCurrent ( )

Accessor for the current column value.

Definition at line 218 of file Record.cpp.
Referenced by Transaction::buildRecord(), and Report::buildRecord().

const nsAReadableString & Record::rColumn::getError ( )

Accessor for the column error message, if one.

Definition at line 226 of file Record.cpp.
Referenced by Transaction::buildRecord(), and Report::buildRecord().

dbMeta::mColumn * Record::rColumn::getMeta ( )

Get the shared static data for this column.

Definition at line 194 of file Record.cpp.
Referenced by Transaction::buildRecord(), and Report::buildRecord().

const nsAReadableString & Record::rColumn::getNew ( )

Accessor for the new column value.

Definition at line 210 of file Record.cpp.

const nsAReadableString & Record::rColumn::getOld ( )

Accessor for the old column value.

Definition at line 202 of file Record.cpp.

Record * Record::rColumn::getSlave ( )

Accessor for a slave record if this column has one.

Definition at line 257 of file Record.cpp.
Referenced by Transaction::buildRecord(), and Report::buildRecord().

void Record::rColumn::putCurrent ( const nsAReadableString & vCurrent )

Set the current value.
This field only comes from the database so it does not need to be validated
Parameters:

vCurrent

Definition at line 312 of file Record.cpp.

void Record::rColumn::putError ( const nsAReadableString & error )

Append to the error message.

Parameters:

error const nsAReadableString& to append

Definition at line 351 of file Record.cpp.

bool Record::rColumn::putNew ( Template * pTemplate,

const nsAReadableString & vNew )

New value of field from user.
This value must be typechecked and error can be generated. Dates are type checked via Java. this should be moved into the Javascript file
Parameters:

template static page definition, holds point to datatype checking Javascript

cx runtime context for evaulating Javascript

vNew new data

Definition at line 282 of file Record.cpp.
Referenced by Transaction::validateFields(), and Report::validateFields().

void Record::rColumn::putOld ( const nsAReadableString & vOld )

Record what is suppose to be in the database.
Empty date const nsAReadableString&s are converted to null
Parameters:

vOld expect column value

Definition at line 246 of file Record.cpp.
Referenced by Transaction::validateFields(), and Report::validateFields().

void Record::rColumn::putSlave ( Record * pSlave )

When a new slave is created, link it to it's master.

Parameters:

slave new slave record

Definition at line 267 of file Record.cpp.

void Record::rColumn::setDefault ( )

before an insert columns are set to their defaul value in case no new value has been sent.

Definition at line 235 of file Record.cpp.

void Record::rColumn::update ( )

Copy values from new to current after error checking is done.
Current values are used when building XML
Definition at line 321 of file Record.cpp.
