方法详细资料

isNew

boolean isNew()

Determines if the current object is new.

返回:

true if the current object is new, false if the object is not new

setNew

void setNew(boolean isNew)

Specifies to the object if it has been set as new.

参数:

isNew - the boolean value to be assigned to the isNew field

getInitialized

int getInitialized()

返回:

the initialized status of columns

setInitialized

void setInitialized(int initialized)

参数:

initialized - the initialized status of columns

getModified

int getModified()

返回:

the modified status of columns

setModified

void setModified(int modified)

参数:

modified - the modified status of columns

isModified

boolean isModified()

Determines if the object has been modified since the last time this method was called.
We can also determine if this object has ever been modified since its creation.

返回:

true if the object has been modified, false if the object has not been modified

resetIsModified

void resetIsModified()

Resets the object modification status to 'not modified'.

resetPrimaryKeysModified

void resetPrimaryKeysModified()

Resets the primary keys modification status to 'not modified'.

isInitialized

boolean isInitialized(int columnID)

Determines if the columnID has been initialized.
It is useful to determine if a field is null on purpose or just because it has not been initialized.

参数:

columnID - column id

返回:

true if the field has been initialized, false otherwise

isModified

boolean isModified(int columnID)

Determines if the column has been modified.

参数:

columnID - column id

返回:

true if the field has been modified, false if the field has not been modified

isInitialized

boolean isInitialized(java.lang.String column)

Determines if the column has been initialized.
It is useful to determine if a field is null on purpose or just because it has not been initialized.

参数:

column - column name

返回:

true if the field has been initialized, false otherwise

isModified

boolean isModified(java.lang.String column)

Determines if the column has been modified.

参数:

column - column name

返回:

true if the field has been modified, false if the field has not been modified
