reserveDictionaryIds

public HeapIntVector reserveDictionaryIds(int capacity)

从类复制的说明: AbstractColumnVector

Reserve a integer column for ids of dictionary. DictionaryIds maybe inconsistent with AbstractColumnVector.setDictionary(org.apache.flink.table.dataformat.vector.Dictionary). Suppose a ColumnVector's data comes from two pages. Perhaps one page uses a dictionary and the other page does not use a dictionary. The first page that uses a field will have dictionaryIds, which requires decoding the first page (Out batch does not support a mix of dictionary).

覆盖:

reserveDictionaryIds 在类中 AbstractHeapVector

getDictionaryIds

public HeapIntVector getDictionaryIds()

从类复制的说明: AbstractHeapVector

Returns the underlying integer column for ids of dictionary.

覆盖:

getDictionaryIds 在类中 AbstractHeapVector

getBoolean

public boolean getBoolean(int i)

指定者:

getBoolean 在接口中 BooleanColumnVector
