Method Detail

init

public boolean init()

Description copied from class: MMObjectBuilder

Initializes this builder The property 'mmb' needs to be set for the builder before this method can be called. The method retrieves data from the TypeDef builder, or adds data to that builder if the current builder is not yet registered.

Overrides:

init in class MMObjectBuilder

Returns:

true if init was completed, false if uncompleted.

public MMObjectNode getVersionNode(String name,
                                   String type)

Parameters:

name - the name of the component we want to get know the version information about

type - the type of tye component we want to get information about (application/builder)

Returns:

the node that contains version information about "name", "type" or null if no version information is avaiable

Throws:

SearchQueryException

Since:

MMBase-1.7
