Modifier and Type | Method and Description |
---|---|
static float |
get(ArrowBuf buffer,
int index)
Given a data buffer, get the value stored at a particular position
in the vector.
|
float |
get(int index)
Get the element at the given index from the vector.
|
void |
get(int index,
NullableFloat4Holder holder)
Get the element at the given index from the vector and
sets the state in holder.
|
Types.MinorType |
getMinorType()
Get minor type for this vector.
|
Float |
getObject(int index)
Same as
get(int) . |
FieldReader |
getReader()
Get a reader that supports reading values from this vector.
|
TransferPair |
getTransferPair(String ref,
BufferAllocator allocator)
Construct a TransferPair comprising of this and a target vector of
the same type.
|
double |
getValueAsDouble(int index)
Gets the value at the given index.
|
TransferPair |
makeTransferPair(ValueVector to)
Construct a TransferPair with a desired target vector of the same type.
|
void |
set(int index,
float value)
Set the element at the given index to the given value.
|
void |
set(int index,
Float4Holder holder)
Set the element at the given index to the value set in data holder.
|
void |
set(int index,
int isSet,
float value)
Store the given value at a particular position in the vector.
|
void |
set(int index,
NullableFloat4Holder holder)
Set the element at the given index to the value set in data holder.
|
void |
setSafe(int index,
float value)
Same as
set(int, float) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
void |
setSafe(int index,
Float4Holder holder)
Same as
set(int, Float4Holder) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
void |
setSafe(int index,
int isSet,
float value)
Same as
set(int, int, float) except that it handles the case
when index is greater than or equal to current value capacity of the
vector. |
void |
setSafe(int index,
NullableFloat4Holder holder)
Same as
set(int, NullableFloat4Holder) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
void |
setSafeWithPossibleTruncate(int index,
double value)
Sets the value at the given index, note this value may be truncated internally.
|
void |
setWithPossibleTruncate(int index,
double value)
Sets the value at the given index, note this value may be truncated internally.
