◆addCol() [1/4]

void com.vertica.sdk.VerticaBlock.addCol(ByteBuffer arg, int colstride, VerticaType dt, String colName)

Add the location for reading a particular argument.

Parameters

  • arg: The base location to find data.
  • colstride: The stride between data instances.
  • dt: The type of input.
  • colName: Name of the column

◆addCol() [2/4]

void com.vertica.sdk.VerticaBlock.addCol(ByteBuffer arg, int colstride, VerticaType dt)

Add the location for reading a particular argument.

Parameters

  • arg: The base location to find data.
  • colstride: The stride between data instances.
  • dt: The type of input.

◆addCol() [3/4]

void com.vertica.sdk.VerticaBlock.addCol(ByteBuffer arg, ByteBuffer da, int colstride, VerticaType dt)

Add the location for reading a particular argument.

Parameters

  • arg: The base location to find data.
  • da: The location to find out of band string data.
  • colstride: The stride between data instances.
  • dt: The type of input.

◆addCol() [4/4]

void com.vertica.sdk.VerticaBlock.addCol(ByteBuffer arg, ByteBuffer da, int colstride, VerticaType dt, String colName)

Add the location for reading a particular argument.

Parameters

  • arg: The base location to find data.
  • da: The location to find out of band string data.
  • colstride: The stride between data instances.
  • dt: The type of input.
  • colName: Name of the column

◆getColDataAreaRef()

ByteBuffer com.vertica.sdk.VerticaBlock.getColDataAreaRef(int idx)

Get the ByteBuffer that stores out of line string data (Data Area) for the idx'th argument

Parameters

  • idx: The column number to retrieve from the input row.

Returns the ByteBuffer

◆getColRef()

ByteBuffer com.vertica.sdk.VerticaBlock.getColRef(int idx)

Example

ByteBuffer a = arg_reader.getColPtr(0);

Parameters

  • idx: The column number to retrieve from the input row.

Returns a ByteBuffer to the idx'th argument, containing data for the column
