public UInt32Builder(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

UInt32Builder

public UInt32Builder(@SharedPtr @Cast(value={"","std::shared_ptr<arrow::DataType>"})
                     DataType type,

Method Detail

Append

@ByVal
public Status Append(@Cast(value="const arrow::NumericBuilder<arrow::UInt32Type>::value_type")
                             int val)

Append a single scalar and increase the size if necessary.
