Constructor Detail

ScalarAggregateOptions

public ScalarAggregateOptions(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

ScalarAggregateOptions

public ScalarAggregateOptions(long size)

Native array allocator. Access with Pointer.position(long).

ScalarAggregateOptions

public ScalarAggregateOptions(@Cast(value="bool")
                              boolean skip_nulls,

Method Detail

position

public ScalarAggregateOptions position(long position)

Overrides:

position in class Pointer

getPointer

public ScalarAggregateOptions getPointer(long i)

Overrides:

getPointer in class Pointer

kTypeName

@MemberGetter
public static byte kTypeName(int i)

kTypeName

@MemberGetter
public static String kTypeName()

Defaults

@ByVal

skip_nulls

public ScalarAggregateOptions skip_nulls(boolean setter)

min_count

@Cast(value="uint32_t")
public int min_count()

If less than this many non-null values are observed, emit null.

min_count

public ScalarAggregateOptions min_count(int setter)
