                            int expectedEntries)

Method Detail

writeBoolean

public ColumnBuilder writeBoolean(boolean value)

Description copied from interface: ColumnBuilder

Write a boolean to the current entry;

Specified by:

writeBoolean in interface ColumnBuilder

writeObject

public ColumnBuilder writeObject(java.lang.Object value)

Write an Object to the current entry, which should be the Boolean type;

Specified by:

writeObject in interface ColumnBuilder

write

public ColumnBuilder write(Column column,
                           int index)

Description copied from interface: ColumnBuilder

Write value at index of passing column

Caller should make sure that value at index is not null

Specified by:

write in interface ColumnBuilder

Parameters:

column - source column whose type should be same as ColumnBuilder

index - index of source column to read from

writeTsPrimitiveType

public ColumnBuilder writeTsPrimitiveType(TsPrimitiveType value)

Description copied from interface: ColumnBuilder

Write a TsPrimitiveType sequences to the current entry;

Specified by:

writeTsPrimitiveType in interface ColumnBuilder

appendNull

public ColumnBuilder appendNull()

Description copied from interface: ColumnBuilder

Appends a null value to the block.

Specified by:

appendNull in interface ColumnBuilder

build

public Column build()

Description copied from interface: ColumnBuilder

Builds the block. This method can be called multiple times.

Specified by:

build in interface ColumnBuilder

getDataType

public TSDataType getDataType()

Specified by:

getDataType in interface ColumnBuilder

getRetainedSizeInBytes

public long getRetainedSizeInBytes()

Description copied from interface: ColumnBuilder

Returns the retained size of this column in memory, including over-allocations. This method is called from the inner most execution loop and must be fast.

Specified by:

getRetainedSizeInBytes in interface ColumnBuilder

newColumnBuilderLike
