| readOnly | | protected boolean readOnly(Code) | | |
| state | | protected int state(Code) | | |
| AbstractField | | protected AbstractField(String name, Field field)(Code) | | Create a field object based on another field.
The newly created field shared the datatype of it's parent
(which means that any changes to the datatype affects both fields).
Parameters:
name - the name of the field
Parameters:
field - the parent field |
| AbstractField | | protected AbstractField(String name, Field field, boolean cloneDataForRewrite)(Code) | | Create a field object based on another field.
Parameters:
name - the name of the field
Parameters:
field - the parent field
Parameters:
cloneDataForRewrite - determines whether the datatype of the parent field is copied (which means it can be alteredwithout affecting the original datatype) |
| AbstractField | | protected AbstractField(String name, int type, int listItemType, int state, DataType<Object> dataType)(Code) | | Create a field object
Parameters:
name - the name of the field
Parameters:
type - the identifier for the MMBase base type for this field
Parameters:
listItemType - If the type of this field is TYPE_LIST, then this is the MMBase base type for the list elements.
Parameters:
state - identifier (virtual, persistent, system, systemvirtual)
Parameters:
dataType - the data type of the field |
| equals | | public boolean equals(Object o)(Code) | | Whether data type equals to other data type. Only key and type are considered. DefaultValue and
required properties are only 'utilities'.
Parameters:
o - the reference object with which to compare. true if o is a DataType of which key and type equal to this' key and type. |

| isTemporary | | public boolean isTemporary()(Code) | | Returns whether a field is a temporary field.
Temporary fields hold data needed by a builder to facilitate certain functionality,
such as holding node references in a transaction.
Temporary fields are never persistent and should normally be ignored.
