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

isNew

void isNew(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

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

copy

B copy(B bean)

Copies the passed bean into the current bean.

参数:

bean - the bean to copy into the current bean

返回:

always bean

copy

B copy(B bean,
     int... fieldList)

Copies the passed bean into the current bean.

参数:

bean - the bean to copy into the current bean

fieldList - the column id list to copy into the current bean

返回:

always bean

copy

B copy(B bean,
     java.lang.String... fieldList)

Copies the passed bean into the current bean.

参数:

bean - the bean to copy into the current bean

fieldList - the column name list to copy into the current bean

返回:

always bean

getValue
