All known Subclasses: org.ofbiz.entity.GenericValue, org.ofbiz.entity.GenericPK,
| GenericEntity | | public class GenericEntity extends Observable implements Map,LocalizedMap,Serializable,Comparable,Cloneable,Reusable(Code) | | Generic Entity Value Object - Handles persisntence for any defined entity.
Note that this class extends Observable to achieve change notification for
Observers. Whenever a field changes the name of the field will be passed to
the notifyObservers() method, and through that to the update() method of each
Observer.

| cachedHashCode | | protected int cachedHashCode(Code) | | |
| delegatorName | | protected String delegatorName(Code) | | Name of the GenericDelegator, used to reget the GenericDelegator when deserialized
|
| entityName | | protected String entityName(Code) | | Contains the entityName of this entity, necessary for efficiency when creating EJBs
|
| fields | | protected Map fields(Code) | | Contains the fields for this entity. Note that this should always be a
HashMap to allow for two things: non-synchronized reads (synchronized
writes are done through synchronized setters) and being able to store
null values. Null values are important because with them we can distinguish
between desiring to set a value to null and desiring to not modify the
current value on an update.
|
| generateHashCode | | protected boolean generateHashCode(Code) | | |
| internalDelegator | | protected transient GenericDelegator internalDelegator(Code) | | Reference to an instance of GenericDelegator used to do some basic operations on this entity value. If null various methods in this class will fail. This is automatically set by the GenericDelegator for all GenericValue objects instantiated through it. You may set this manually for objects you instantiate manually, but it is optional.
|
| isFromEntitySync | | protected boolean isFromEntitySync(Code) | | This is an internal field used to specify that a value has come from a sync process and that the auto-stamps should not be over-written
|
| modelEntity | | protected transient ModelEntity modelEntity(Code) | | Contains the ModelEntity instance that represents the definition of this entity, not to be serialized
|
| modified | | protected boolean modified(Code) | | Denotes whether or not this entity has been modified, or is known to be out of sync with the persistent record
|
| mutable | | protected boolean mutable(Code) | | Used to specify whether or not this representation of the entity can be changed; generally cleared when this object comes from a cache
|
| GenericEntity | | protected GenericEntity()(Code) | | Creates new GenericEntity - Should never be used, prefer the other options.
|
| clear | | public void clear()(Code) | | |
| clone | | public Object clone()(Code) | | Clones this GenericEntity, this is a shallow clone & uses the default shallow HashMap clone
Object that is a clone of this GenericEntity |
| compareTo | | public int compareTo(Object obj)(Code) | | Compares this GenericEntity to the passed object
Parameters:
obj - Object to compare this to int representing the result of the comparison (-1,0, or 1) |
| containsPrimaryKey | | public boolean containsPrimaryKey()(Code) | | Returns true if the entity contains all of the primary key fields.
|
| containsPrimaryKey | | public boolean containsPrimaryKey(boolean requireValue)(Code) | | |
| containsValue | | public boolean containsValue(Object value)(Code) | | |
| createGenericEntity | | public static GenericEntity createGenericEntity(GenericEntity value)(Code) | | Copy Factory Method: Creates new GenericEntity from existing GenericEntity
|
| equals | | public boolean equals(Object obj)(Code) | | Determines the equality of two GenericEntity objects, overrides the default equals
Parameters:
obj - The object (GenericEntity) to compare this two boolean stating if the two objects are equal |
| get | | public Object get(String name, Locale locale)(Code) | | Checks a resource bundle for a value for this field using the entity name, the field name
and a composite of the Primary Key field values as a key. If no value is found in the
resource then the field value is returned. Uses the default-resource-name from the entity
definition as the resource name. To specify a resource name manually, use the other getResource method.
So, the key in the resource bundle (properties file) should be as follows:
......
For example:
ProductType.description.FINISHED_GOOD
Parameters:
name - The name of the field on the entity
Parameters:
locale - The locale to use when finding the ResourceBundle, if null uses the defaultlocale for the current instance of Java If the corresponding resource is found and contains a key as described above, then thatproperty value is returned; otherwise returns the field value |
| get | | public Object get(String name, String resource, Locale locale)(Code) | | Same as the getResource method that does not take resource name, but instead allows manually
specifying the resource name. In general you should use the other method for more consistent
naming and use of the corresponding properties files.
Parameters:
name - The name of the field on the entity
Parameters:
resource - The name of the resource to get the value from; if null defaults to thedefault-resource-name on the entity definition, if specified there
Parameters:
locale - The locale to use when finding the ResourceBundle, if null uses the defaultlocale for the current instance of Java If the specified resource is found and contains a key as described above, then thatproperty value is returned; otherwise returns the field value |

| set | | public void set(String name, Object value)(Code) | | Sets the named field to the passed value, even if the value is null
Parameters:
name - The field name to set
Parameters:
value - The value to set |
| set | | public synchronized Object set(String name, Object value, boolean setIfNull)(Code) | | Sets the named field to the passed value. If value is null, it is only
set if the setIfNull parameter is true. This is useful because an update
will only set values that are included in the HashMap and will store null
values in the HashMap to the datastore. If a value is not in the HashMap,
it will be left unmodified in the datastore.
Parameters:
name - The field name to set
Parameters:
value - The value to set
Parameters:
setIfNull - Specifies whether or not to set the value if it is null |

Parameters:
fields - The fields Map to get the values from
Parameters:
setIfEmpty - Used to specify whether empty/null values in the field Map should over-write non-empty values in this entity
Parameters:
namePrefix - If not null or empty will be pre-pended to each field name (upper-casing the first letter of the field name first), and that will be used as the fields Map lookup name instead of the field-name
Parameters:
pks - If null, get all values, if TRUE just get PKs, if FALSE just get non-PKs |
| setBytes | | public void setBytes(String name, byte[] bytes)(Code) | | Sets a field with an array of bytes, wrapping them automatically for easy use.
