grails.beans.util.LazyBeanMap

All Implemented Interfaces and Traits:

java.util.Map<java.lang.String, java.lang.Object>
```
@groovy.transform.CompileStatic
class LazyBeanMap
extends java.lang.Object
implements java.util.Map<java.lang.String, java.lang.Object>
```
A map that backs onto a bean. The map is not initialized from the beans property values on creation, but instead lazily reads the values on demand. No caching is applied, so each read results in a reflective call to retrieve the property. Users of this API should apply their own caching strategy if necessary.

Note that the java.util.Map#values() and java.util.Map#entrySet() implementations are expensive operations as they will read all properties of the target bean and should be used with caution.

Additionally the Map#remove(java.lang.Object) and java.util.Map#clear() methods are not implemented and will throw java.lang.UnsupportedOperationException.
deprecated:
use LazyMetaPropertyMap instead
