Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression1.asInstanceOf[String]

will not. In the latter example, because the type argument is erased as
part of compilation it is not possible to check whether the contents of the list are of the requested typed.

The eq
method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on
non-null instances of AnyRef
:
* It is reflexive: for any non-null instance x
of type AnyRef
, x.eq(x)
returns true
.
* It is symmetric: for any non-null instances x
and y
of type AnyRef
, x.eq(y)
returns true
if and
only if y.eq(x)
returns true
.
* It is transitive: for any non-null instances x
, y
, and z
of type AnyRef
if x.eq(y)
returns true
and y.eq(z)
returns true
, then x.eq(z)
returns true
.
Additionally, the eq
method has three other properties.
* It is consistent: for any non-null instances x
and y
of type AnyRef
, multiple invocations of
x.eq(y)
consistently returns true
or consistently returns false
.
* For any non-null instance x
of type AnyRef
, x.eq(null)
and null.eq(x)
returns false
.
* null.eq(null)
returns true
.
When overriding the equals
or hashCode
methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2
), they
should be equal to each other (o1 == o2
) and they should hash to the same value (o1.hashCode == o2.hashCode
).

This method is used to compare the receiver object (this

If you override this method, you should verify that your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to override hashCode
to ensure that objects
that are "equal" (o1.equals(o2)
returns true
) hash to the same

Set this to use your own form template when rendering a Record to a form.
Set this to use your own form template when rendering a Record to a form.
This template is any given XHtml that contains three nodes acting as placeholders such as:
<lift:field_label name="firstName"/> - the label for firstName field will be rendered here <lift:field name="firstName"/> - the firstName field will be rendered here (typically an input field) <lift:field_msg name="firstName"/> - the <lift:msg> will be rendered here hafing the id given by uniqueFieldId of the firstName field.
Example.
Having:
class MyRecord extends Record[MyRecord] {
def meta = MyRecordMeta
object firstName extends StringField(this, "John")
}
object MyRecordMeta extends MyRecord with MetaRecord[MyRecord] { override def mutable_? = false }
...
val rec = MyRecordMeta.createRecord.firstName("McLoud")
val template = <div> <div> <div><lift:field_label name="firstName"/></div> <div><lift:field name="firstName"/></div> <div><lift:field_msg name="firstName"/></div> </div> </div>

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)

not be equal (o1.equals(o2)
returns false
). A degenerate implementation could always return 0
.
However, it is required that if two objects are equal (o1.equals(o2)
returns true
