Constructor Detail

ElementHolder

public ElementHolder(InstanceElement[] instances)
              throws AoException

Create a new ElementHolder from an array of instance elements. The base attributes are automatically detected and the matching application attribute names are stored in the internal hashtable baseAttributeNames.

Parameters:

instances - Array of instance elements to create the ElementHolder from.

Throws:

AoException

ElementHolder

public ElementHolder(NameValueUnit[][] inNvu,
             java.util.Hashtable<java.lang.String,java.lang.String> baseAttributes)
              throws ExecutableException

Create a new ElementHolder from a NameValueUnit[][]. The base attributes must be supplied as a Hashtable. All null entries in the NameValueUnit[][] are removed.

Parameters:

inNvu - The NameValueUnit[][] holding the instances ant their attributes.

baseAttributes - The Hashtable holding the base attributes.

Throws:

ExecutableException - if base attribute name or id is missing.
