For each pattern, create an inverted index containing: {@code normalized(token) -> patternList} so that we can quickly compute the list of candidate p

Ensures that there is enough room in the buffer to directly access the next N chars via buffer[].

Returns the builder for a suffix tree made from <code>sequence</code>.

Returns the length (number of elements) of the range most recently acquired from {@link #next()}.

Sets the number of base vectors <i>k </i>. @param k the number of base vectors

Sets the maximum number of iterations the k-means algorithm is allowed to perform.

Sets the <strong>current</strong> token image to the provided buffer. @param array buffer in which the <strong>current</strong> token's image should

@return true if the decrease in the approximation error is smaller than the <code>stopThreshold </code>

raw value of token type field.

Advance one character ahead, or return {@code EOF} on end of input.

Builds a term-phrase matrix in the same space as the main term-document matrix. If the processing context contains no phrases, {@link VectorSpaceModel

Build a suffix tree for a given sequence and check if it contains all suffixes of the input sequence (ending in leaves).

Performs STC clustering of documents.

Compute the number of common elements in two (sorted) lists.

Extracts just the attributes of an instance (no top-level type information is preserved). @param classToName Class to name mapping provider.

Helper function to fixup eof after reading buffer directly.

Asserts that the matrix is equivalent to the provided array of values.

Iterate over all documents, fields and sentences in {@link PreprocessingContext#allTokens}.

Determines the ordering of objects in this priority queue. Subclasses must define this one method.

Normalizes column vectors of matrix <code>A</code> so that their L2 norm (Euclidean distance) is equal to 1.0. @param A matrix to normalize @param wo

Parses a {@link JsonObject} from a source. <pre> JsonObject json = {@link JsonParser}.object().from("{\"a\":[true,false], \"b\":1}"); </pre>

Invoked after <code>state</code> is fully traversed. @param state Identifier of the completed state.
