Method Detail

getName

String getName()

getType

Class getType()

Returns:

the type of object contained within this column.

getComponentType

Class getComponentType()

Get the array component type, or the type itself. For basic types, this is just the type. For example, if you have a column of java.lang.String, this also returns java.lang.String. For array types (java Arrays), or DbArray (which would be returned by getType), you get the type that is contained within the array. For example, if a single row in this column contains a DbDoubleArray, getComponentType returns double.

Returns:

if type is an array, the type of object within the array. Otherwise type itself.

getDirect

default Object getDirect()

Get the contents of this data column in array form. Note that this will return an array of the appropriate primitive type for columns of non-Boolean primitive types.

Returns:

An appropriately-typed array containing the full contents of this data column

getDirect

default Object getDirect(long startIndexInclusive,
                         long endIndexExclusive)

Get the contents of a range of this data column in array form. See DataColumn.getDirect() for an explanation of return types. Note that it's required that endIndexExclusive - startIndexInclusive < Integer.MAX_VALUE.

Parameters:

startIndexInclusive - The first position in the data column to include, inclusive

endIndexExclusive - One more than the last position in the data column to include

Returns:

An appropriately-typed array containing the contents of the specified range of this data column

getDirect

default Object getDirect(long... indexes)

getDirect

default Object getDirect(int... indexes)

get

TYPE get(long index)

Returns the value in the column at the row designated by the index

Parameters:

index - - the index of the row for which the data is being retrieved

Returns:

the value in the column at the row designated by the index

get

TYPE[] get(long startIndexInclusive,
           long endIndexExclusive)

Return the column's values for the specified row range. Note that this will be a boxed array, for data columns of primitive types.

Parameters:

startIndexInclusive - The first position in the data column to include, inclusive

endIndexExclusive - One more than the last position in the data column to include

Returns:

Return the column's values for the specified row range

get

TYPE[] get(long... indexes)

Return the column's values for the specified rows. Note that this will be a boxed array, for data columns of primitive types.

Parameters:

indexes - The row indexes to fetch

Returns:

Return the column's values for the specified rows

get

TYPE[] get(int... indexes)

Return the column's values for the specified rows. Note that this will be a boxed array, for data columns of primitive types.

Parameters:

indexes - The row indexes to fetch

Returns:

Return the column's values for the specified rows
