Method Detail

create

public ResultSet create(ColumnMetaData.AvaticaType elementType,
                        Iterable<Object> elements)

Description copied from interface: ArrayImpl.Factory

Creates a ResultSet from the given list of values per Array.getResultSet().

Specified by:

create in interface ArrayImpl.Factory

Parameters:

elementType - The type of the elements

elements - The elements

createArray

public Array createArray(ColumnMetaData.AvaticaType elementType,
                         Iterable<Object> elements)

Description copied from interface: ArrayImpl.Factory

Creates an Array from the given list of values, converting any primitive values into the corresponding objects.

Specified by:

createArray in interface ArrayImpl.Factory

Parameters:

elementType - The type of the elements

elements - The elements

createResultSetRowsForArrayData

private List<List<Object>> createResultSetRowsForArrayData(Iterable<Object> elements)

Creates the row-level view over the values that will make up an Array. The Iterator has a row per Array element, each row containing two columns. The second column is the array element and the first column is the offset into the array of that array element (one-based, not zero-based).

The ordering of the rows is not guaranteed to be in the same order as the array elements.

A list of elements:

[1, 2, 3]

might be converted into

Iterator{ [1, 1], [2, 2], [3, 3] }

Parameters:

elements - The elements of an array.

createRowForArrayData

private Iterator<List<Object>> createRowForArrayData(List<Object> elements)

Creates an row-level view over the values that will make up an Array. The Iterator has one entry which has a list that also has one entry.

A provided list of elements

[1, 2, 3]

would be converted into

Iterator{ [ [1,2,3] ] }

Parameters:

elements - The elements of an array
