java.lang.Objectpitt.search.semanticvectors.VectorStoreReaderText
public class VectorStoreReaderText
This class provides methods for reading a VectorStore from a textfile.
The textfile should start with an optional header line,
"-dimensions|N
".
All subsequent lines should be of the form
String|Num1|Num2|...|NumN
The serialization currently presumes that the object (in the ObjectVectors) should be serialized as a String.
This class is mainly for interoperability with plain text file formats: normal (fast) implementations should use the internal VectorStoreReader class that uses Lucene's I/O functions.

getVector(java.lang.Object desiredObject)
Given an object, get its corresponding vector This implementation only works for string objects so far |
static ObjectVector |
parseVectorLine(java.lang.String line)
Returns an object vector from a text line. |
