field
protected final com.sun.codemodel.JFieldRef field
- Reference to the
AbstractListField.field
of the target object.
AbstractListField.Accessor
protected AbstractListField.Accessor(com.sun.codemodel.JExpression $target)
unbox
protected final com.sun.codemodel.JExpression unbox(com.sun.codemodel.JExpression exp)
box
protected final com.sun.codemodel.JExpression box(com.sun.codemodel.JExpression exp)
ref
protected final com.sun.codemodel.JExpression ref(boolean canBeNull)
- Returns a reference to the List field that stores the data.
Using this method hides the fact that the list is lazily
created.
- Parameters:
canBeNull
- if true, the returned expression may be null (this is
when the list is still not constructed.) This could be
useful when the caller can deal with null more efficiently.
When the list is null, it should be treated as if the list
is empty.
if false, the returned expression will never be null.
This is the behavior users would see.
count
public com.sun.codemodel.JExpression count()
unsetValues
public void unsetValues(com.sun.codemodel.JBlock body)
- Description copied from interface:
FieldAccessor
- Generates a code fragment to remove any "set" value
and move this field to the "unset" state.
- Parameters:
body
- The code will be appended at the end of this block.
hasSetValue
public com.sun.codemodel.JExpression hasSetValue()
- Description copied from interface:
FieldAccessor
- Return an expression that evaluates to true only when
this field has a set value(s).
- Returns:
- null
if the isSetXXX/unsetXXX method does not make sense
for the given field.
