Write a byte to the file. If the file has not been opened for writing, an IOException will be raised only when an attempt is made to write the buffer

Translates internal id to original id @param transId @return

Writes an <code>int</code> to the file as four bytes, high byte first. @param v an <code>int</code> to be written. @throws IOException if an I/O erro

Get the length of the file. The data in the buffer (which may not have been written the disk yet) is taken into account. @return the length of the fi

Reads a signed 32-bit integer from this file. This method reads 4 bytes from the file. If the bytes read, in order, are <code>b1</code>, <code>b2</cod

Read a byte of data from the file, blocking until data is available. @return the next byte of data, or -1 if the end of the file is reached.

Get i'th outedge @param i @return edge object

Execute sharding by reading edges from a inputstream @param inputStream @param format graph input format @throws IOException

Set the position in the file for the next read or write. @param pos the offset (in bytes) from the start of the file. @throws IOException if an I/O e

Translates original vertex id to internal vertex id @param origId @return

Get i'th in-edge @param i @return edge object

Format the given LogRecord. @param record the log record to be formatted. @return a formatted log record

@return the number of vertices in the current graph

Sets the bytes->edge value converter object. If the object is null, then no edge-values are read (only adjacency information). @param edataConverter

Sets the bytes->vertex value converter object. @param vertexDataConverter

Get i'th edge (in- our out-edge). @param i @return edge object

Object for translating from internal to original vertex ids @return

Runs the GraphChi program for given number of iterations. <b>Note:</b> Prior to calling this, you must have set the edge-data and vertex-data converte

Merge too distribution. If either has a negative entry for some id, it will remain negative in the merged distribution (see createAvoidDistribution).

Disable/enable writing of in-edges (enabled by default) @param modifiesInedges

Encode a walk. Note, as sourceIdx is the highest order bits, the walks can be sorted by source simply by sorting the list. @param sourceId index of th

Reads an unsigned 8-bit number from this file. This method reads a byte from this file and returns that byte. <p/> This method blocks until the byte i

GraphChi uses internal vertex ids. To translate from the internal ids to the ids used in the original graph, obtain VertexIdTranslate object by using

Skips exactly <code>n</code> bytes of input. This method blocks until all the bytes are skipped, the end of the stream is detected, or an exception is

Enumerate vertices using a callback @see edu.cmu.graphchi.vertexdata.ForeachCallback @param numVertices number of vertices in the graph (hint: use eng

Reads the next line of text from this file. This method successively reads bytes from the file, starting at the current file pointer, until it reache

Get the scheduler bound to this computation. @return scheduler

Ask a vertex to be updated. @param vertexId

Get vertex-id of the i'th out edge (avoid creating the edge-object). @param i
