Examples with PrimitiveFloatCodec com.datastax.oss.driver.api.core.type.codec.PrimitiveFloatCodec used on opensource projects

Example 1 with PrimitiveFloatCodec

use of com.datastax.oss.driver.api.core.type.codec.PrimitiveFloatCodec in project java-driver by datastax.

the class SettableByIndex method setFloat.

/**
 * Sets the {@code i}th value to the provided Java primitive float.
 *
 * <p>By default, this works with CQL type {@code float}.
 *
 * <p>To set the value to CQL {@code NULL}, use {@link #setToNull(int)}, or {@code set(i, v,
 * Float.class)}.
 *
 * @throws IndexOutOfBoundsException if the index is invalid.
 */

@CheckReturnValue

    DataType cqlType = getType(i);

    return (codec instanceof PrimitiveFloatCodec) ? setBytesUnsafe(i, ((PrimitiveFloatCodec) codec).encodePrimitive(v, protocolVersion())) : set(i, v, codec);
}

Example 2 with PrimitiveFloatCodec

use of com.datastax.oss.driver.api.core.type.codec.PrimitiveFloatCodec in project java-driver by datastax.

the class GettableByIndex method getFloat.

/**
 * Returns the {@code i}th value as a Java primitive float.
 *
 * <p>By default, this works with CQL type {@code float}.
 *
 * <p>Note that, due to its signature, this method cannot return {@code null}. If the CQL value is
 * {@code NULL}, it will return {@code 0.0}. If this doesn't work for you, either call {@link
 * #isNull(int)} before calling this method, or use {@code get(i, Float.class)} instead.
 *
 * @throws IndexOutOfBoundsException if the index is invalid.
