Class ColumnProperty

  • All Implemented Interfaces:
    Property, Serializable
    @Deprecated
public final class ColumnProperty
extends Object
implements Property
    Deprecated.
    As of 8.0, no replacement available.
    ColumnProperty represents the value of one column in a RowItem. In addition to the value, ColumnProperty also contains some basic column attributes such as nullability status, read-only status and data type. Note that depending on the QueryDelegate in use this does not necessarily map into an actual column in a database table.

    • Method Detail

      • getValue

        public Object getValue()
        Deprecated.
        Returns the current value for this property. To get the previous value (if one exists) for a modified property use getOldValue().
        Specified by:
        getValue in interface Property
        Returns:

      • getOldValue

        public Object getOldValue()
        Deprecated.
        Returns the original non-modified value of this property if it has been modified.
        Returns:
        The original value if isModified() is true, getValue() otherwise.

      • setValue

        public void setValue​(Object newValue)
              throws Property.ReadOnlyException,
                     Converter.ConversionException
        Deprecated.
        Description copied from interface: Property
        Sets the value of the Property.

        Implementing this functionality is optional. If the functionality is missing, one should declare the Property to be in read-only mode and throw Property.ReadOnlyException in this function.

        Note : Since Vaadin 7.0, setting the value of a non-String property as a String is no longer supported.
        Specified by:
        setValue in interface Property
        Parameters:
        newValue - New value of the Property. This should be assignable to the type returned by getType
        Throws:
        Property.ReadOnlyException - if the object is in read-only mode
        Converter.ConversionException

      • getType

        public Class<?> getType()
        Deprecated.
        Description copied from interface: Property
        Returns the type of the Property. The methods getValue and setValue must be compatible with this type: one must be able to safely cast the value returned from getValue to the given type and pass any variable assignable to this type as an argument to setValue.
        Specified by:
        getType in interface Property
        Returns:
        type of the Property

      • isReadOnly

        public boolean isReadOnly()
        Deprecated.
        Description copied from interface: Property
        Tests if the Property is in read-only mode. In read-only mode calls to the method setValue will throw ReadOnlyException and will not modify the value of the Property.
        Specified by:
        isReadOnly in interface Property
        Returns:
        true if the Property is in read-only mode, false if it's not

      • isReadOnlyChangeAllowed

        public boolean isReadOnlyChangeAllowed()
        Deprecated.
        Returns whether the read-only status of this property can be changed using setReadOnly(boolean).

        Used to prevent setting to read/write mode a property that is not allowed to be written by the underlying database. Also used for values like VERSION and AUTO_INCREMENT fields that might be set to read-only by the container but the database still allows writes.

        Returns:
        true if the read-only status can be changed, false otherwise.

      • setReadOnly

        public void setReadOnly​(boolean newStatus)
        Deprecated.
        Description copied from interface: Property
        Sets the Property's read-only mode to the specified status. This functionality is optional, but all properties must implement the isReadOnly mode query correctly.
        Specified by:
        setReadOnly in interface Property
        Parameters:
        newStatus - new read-only status of the Property

      • isPrimaryKey

      • setVersionColumn

        public void setVersionColumn​(boolean versionColumn)

        Deprecated.

      • isPersistent

        public boolean isPersistent()
        Deprecated.
        Return whether the value of this property should be persisted to the database.
        Returns:
        true if the value should be written to the database, false otherwise.

      • isRowIdentifier

        public boolean isRowIdentifier()
        Deprecated.
        Returns whether or not this property is used as a row identifier.
