Method Detail

get

public java.lang.Object get(java.lang.String attributeName)

Specified by:

get in interface DynamicallyAccessible

get

public static java.lang.Object get(java.lang.Object receiver,
                                   java.lang.String attributeName)

hasAttribute

public boolean hasAttribute(java.lang.String attributeName)

Determines whether an attribute of the given name exists on this object's definition, or if not, if there is a javabeans-style accessor named appropriately for that attribute. Put another way, determines whether a get() call would work against this attribute name. The existing implementation is inefficient, but simple to maintain.

Specified by:

hasAttribute in interface DynamicallyAccessible

hasAttribute

public static boolean hasAttribute(java.lang.Object receiver,
                                   java.lang.String attributeName)

getAccessorSelector

protected java.lang.String getAccessorSelector(java.lang.String attributeName)

Deprecated. This method is deprecated in favour of the static _getAccessorSelector(receiver,attribute)

_getAccessorSelector

protected static java.lang.String _getAccessorSelector(java.lang.Object receiver,
                                                       java.lang.String attributeName)

hasAccessor

public boolean hasAccessor(java.lang.String attributeName)

Specified by:

hasAccessor in interface DynamicallyAccessible

hasAccessor

public static boolean hasAccessor(java.lang.Object receiver,
                                  java.lang.String attributeName)

camel

public static java.lang.String camel(java.lang.String string)

Deprecated. This method has been moved to net.israfil.foundation.core.Strings.camel(String)
