Method Detail

handlePrefix

public Node handlePrefix(PrefixHandler.Phase phase,
                         PrefixNode node,
                         NodeVisitor parentVisitor,
                         QueryContext queryContext)
                  throws QueryProcessingException

Description copied from interface: PrefixHandler

Handle a given prefix node.

Specified by:

handlePrefix in interface PrefixHandler

Overrides:

handlePrefix in class BaseNumericalPrefix

Parameters:

phase - the "Phase" of the prefix handler, indicating how far in the pipeline we are.In the standard chain, 4 phases are defined: PRE_LINGUISTIC, PRE_TRANSFORM, PRE_MAP, POST_MAP

node - The prefix node to handle

parentVisitor - If your handler is not "terminal", ie, if it supports nesting, it should call this visitor to visit the prefix node's content, additionally to performing its work. Warning: this can be null, in that case, you must not delegate.
For example, a "URL" node handler might be terminal (ie, it will "eat" all its content), whereas a "soundlike" handler will not be. It will only set the correct expansion options and pass control to lower prefixes, to support things like: soundslike:(foo OR bar OR text:coin)

queryContext - access to overridable query-related parameters

Throws:

QueryProcessingException
