Class MojoRowBuilder

java.lang.Object

ai.h2o.mojos.runtime.frame.MojoRowBuilder

public class MojoRowBuilder
extends java.lang.Object

The builder is used to build rows for a MojoFrameBuilder. Rows are constructed by adding values in String form to a builder instance. The rows can then be added to a MojoFrameBuilder by calling MojoFrameBuilder.addRow(MojoRowBuilder). MojoRowBuilders can be initialized in a “strict” mode, where an exception is thrown whenever there is an attempt to set a value to a column name that is not defined in the builder. Additionally, “strict” MojoRowBuilders will throw an exception if there is an attempt to create a row without every column being set a value beforehand.

Method Detail

setValue

public MojoRowBuilder setValue(java.lang.String name,
                               java.lang.String value)

Set a value to the position associated with column name in the row. If this row builder instance is in “strict” mode, an IllegalArgumentException is thrown if name is not found in this builder. Otherwise nothing happens.

The value is specified as a string and the call will try to convert the value to actual column type.

Parameters:

name - The name of the column to where the value should be set

value - The value to be set

setValue

public MojoRowBuilder setValue(int idx,
                               java.lang.String value)

Set a value to an index in the row

Parameters:

idx - The index where the value should be set

value - The value to be set

Parameters:

values - The array of values to be set into the row.

clear

public void clear()

Clear the state of the row builder

size

public int size()

Get the number values a row resulting from this builder would have

Returns:

The number of values

isStrict

public boolean isStrict()

true if this row builder instance is in “strict” mode; false otherwise.

isSet

Determine whether the column associated with name name has had a value set.

Parameters:

true if the column associated with name name has had a value set; false otherwise.

public boolean isSet(int idx)

Determine whether the column at index idx has had a value set.
