---|---|
void |
copyFrom(int fromIndex,
int thisIndex,
UInt1Vector from)
Copies the value at fromIndex to thisIndex (including validity).
|
void |
copyFromSafe(int fromIndex,
int thisIndex,
UInt1Vector from)
Identical to
#copyFrom() but reallocates buffer if index is larger
than capacity. |
byte |
get(int index)
Get the element at the given index from the vector.
|
void |
get(int index,
NullableUInt1Holder holder)
Get the element at the given index from the vector and
sets the state in holder.
|
Types.MinorType |
getMinorType() |
static short |
getNoOverflow(ArrowBuf buffer,
int index)
Given a data buffer, get the value stored at a particular position
in the vector.
|
Byte |
getObject(int index)
Same as
get(int) . |
Short |
getObjectNoOverflow(int index)
Returns the value stored at index without the potential for overflow.
|
FieldReader |
getReader()
Get a reader for this vector.
|
TransferPair |
getTransferPair(String ref,
BufferAllocator allocator)
Construct a transfer pair of this vector and another vector of same type.
|
TransferPair |
makeTransferPair(ValueVector to)
Makes a new transfer pair used to transfer underlying buffers.
|
void |
set(int index,
byte value)
Set the element at the given index to the given value.
|
void |
set(int index,
int value)
Set the element at the given index to the given value.
|
void |
set(int index,
int isSet,
byte value)
Sets the value at index to value isSet > 0, otherwise sets the index position
to invalid/null.
|
void |
set(int index,
NullableUInt1Holder holder)
Set the element at the given index to the value set in data holder.
|
void |
set(int index,
UInt1Holder holder)
Set the element at the given index to the value set in data holder.
|
void |
setNull(int index)
Set the element at the given index to null.
|
void |
setSafe(int index,
byte value)
Same as
set(int, byte) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
void |
setSafe(int index,
int value)
Same as
set(int, int) 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,
byte value)
Same as
set(int, int, byte) but will reallocate the buffer if index
is larger than current capacity. |
void |
setSafe(int index,
NullableUInt1Holder holder)
Same as
set(int, NullableUInt1Holder) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |
void |
setSafe(int index,
UInt1Holder holder)
Same as
set(int, UInt1Holder) except that it handles the
case when index is greater than or equal to existing
value capacity BaseFixedWidthVector.getValueCapacity() . |

public static short getNoOverflow(ArrowBuf buffer, int index)
To avoid overflow, the returned type is one step up from the signed type.
This method is mainly meant for integration tests.
