  3. Public static field

Returns:
property value or null if no property or static field was found

Specified by:
getPropertyValue in interface GrailsClass
Parameters:
name -
type -
Returns:
The property value or null

getPropertyValue

public Object getPropertyValue(String name)
Description copied from interface: GrailsClass

Gets the initial value of the given property on the class

Specified by:
getPropertyValue in interface GrailsClass
Parameters:
name - The name of the property
Returns:
The initial value

hasProperty

public boolean hasProperty(String name)
