HostColumnVector (cudfjni 24.12.0 API)

java.lang.Object
- ai.rapids.cudf.HostColumnVectorCore
- - ai.rapids.cudf.HostColumnVector

All Implemented Interfaces:

AutoCloseable
```
public final class HostColumnVector
extends HostColumnVectorCore
```
Similar to a ColumnVector, but the data is stored in host memory and accessible directly from the JVM. This class holds references to off heap memory and is reference counted to know when to release it. Call close to decrement the reference count when you are done with the column, and call incRefCount to increment the reference count.

```
public HostColumnVector(DType type,
                        long rows,
                        Optional<Long> nullCount,

                        List<HostColumnVectorCore> nestedHcv)
```
    Create a new column vector with data populated on the host.
    
    Parameters:
    
    type - the type of the vector
    
    rows - the number of rows in the vector.
    
    nullCount - the number of nulls in the vector.
    
    hostDataBuffer - The host side data for the vector. In the case of STRING this is the string data stored as bytes.
    
    hostValidityBuffer - Arrow-like validity buffer 1 bit per row, with padding for 64-bit alignment.
    
    offsetBuffer - only valid for STRING this is the offsets into the hostDataBuffer indicating the start and end of a string entry. It should be (rows + 1) ints.
    
    nestedHcv - list of child HostColumnVectorCore(s) for complex types
- Method Detail
  - setEventHandler
```
public HostColumnVector.EventHandler setEventHandler(HostColumnVector.EventHandler newHandler)
```
    Set an event handler for this host vector. This method can be invoked with null to unset the handler.
    
    Parameters:
    
    newHandler - - the EventHandler to use from this point forward
    
    Returns:
    
    the prior event handler, or null if not set.
  - getEventHandler
```
public HostColumnVector.EventHandler getEventHandler()
```
    Returns the current event handler for this HostColumnVector or null if no handler is associated.
  - noWarnLeakExpected
```
public void noWarnLeakExpected()
```
    This is a really ugly API, but it is possible that the lifecycle of a column of data may not have a clear lifecycle thanks to java and GC. This API informs the leak tracking code that this is expected for this column, and big scary warnings should not be printed when this happens.
  - close
```
public void close()
```
    Close this Vector and free memory allocated for HostMemoryBuffer and DeviceMemoryBuffer
    
    Specified by:

    Overrides:
    
    close in class HostColumnVectorCore
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class HostColumnVectorCore
  - incRefCount
```
public HostColumnVector incRefCount()
```
    Increment the reference count for this column. You need to call close on this to decrement the reference count again.
  - getRefCount
```
public int getRefCount()
```
    Returns this column's current refcount
  - copyToDevice
```
public ColumnVector copyToDevice()

```
    Create a new Builder to hold the specified number of rows. Be sure to close the builder when done with it. Please try to use #build(int, Consumer) instead to avoid needing to close the builder.

If any overflow occurs in extracting integral part, an IllegalArgumentException will be thrown. This API is inefficient because of slow double -> decimal conversion, so it is mainly for testing. Compared with scale of [[java.math.BigDecimal]], the scale here represents the opposite meaning.
  - fromStrings
```
public static HostColumnVector fromStrings(String... values)
```
    Create a new string vector from the given values. This API supports inline nulls. This is really intended to be used only for testing as it is slow and memory intensive to translate between java strings and UTF8 strings.

The scale will be zero if all input values are null.
  - fromBoxedBooleans
```
public static HostColumnVector fromBoxedBooleans(Boolean... values)

```
public static HostColumnVector fromBoxedUnsignedLongs(Long... values)
```
    Create a new vector from the given values. This API supports inline nulls, but is much slower than using a regular array and should really only be used for tests.
    Java does not have an unsigned long type, so the values will be treated as if the bits represent an unsigned value.
  - fromBoxedFloats
```
public static HostColumnVector fromBoxedFloats(Float... values)
```
    Create a new vector from the given values. This API supports inline nulls, but is much slower than using a regular array and should really only be used for tests.
  - fromBoxedDoubles
```
public static HostColumnVector fromBoxedDoubles(Double... values)
```
    Create a new vector from the given values. This API supports inline nulls, but is much slower than using a regular array and should really only be used for tests.
  - timestampDaysFromBoxedInts
```
public static HostColumnVector timestampDaysFromBoxedInts(Integer... values)
```
    Create a new vector from the given values. This API supports inline nulls, but is much slower than using a regular array and should really only be used for tests.
  - timestampSecondsFromBoxedLongs
```
public static HostColumnVector timestampSecondsFromBoxedLongs(Long... values)
```
    Create a new vector from the given values. This API supports inline nulls, but is much slower than using a regular array and should really only be used for tests.
  - timestampMilliSecondsFromBoxedLongs
```
public static HostColumnVector timestampMilliSecondsFromBoxedLongs(Long... values)
```
    Create a new vector from the given values. This API supports inline nulls, but is much slower than using a regular array and should really only be used for tests.
  - timestampMicroSecondsFromBoxedLongs
```
public static HostColumnVector timestampMicroSecondsFromBoxedLongs(Long... values)
```
    Create a new vector from the given values. This API supports inline nulls, but is much slower than using a regular array and should really only be used for tests.
  - timestampNanoSecondsFromBoxedLongs
```
public static HostColumnVector timestampNanoSecondsFromBoxedLongs(Long... values)
```
    Create a new vector from the given values. This API supports inline nulls, but is much slower than using a regular array and should really only be used for tests.
