构造器详细资料

ResultsetRowsStatic

public ResultsetRowsStatic(List<? extends Row> rows,
                           ColumnDefinition columnDefinition)

Creates a new RowDataStatic object.

参数:

rows - list of Row instances

columnDefinition - ColumnDefinition for this result set

方法详细资料

addRow

public void addRow(Row row)

从接口复制的说明: ResultsetRows

Adds a row.

指定者:

addRow 在接口中 ResultsetRows

参数:

row - the row to add

afterLast

public void afterLast()

从接口复制的说明: ResultsetRows

Moves to after last.

指定者:

afterLast 在接口中 ResultsetRows

beforeFirst

public void beforeFirst()

从接口复制的说明: ResultsetRows

Moves to before first.

指定者:

beforeFirst 在接口中 ResultsetRows

beforeLast

public void beforeLast()

从接口复制的说明: ResultsetRows

Moves to before last.

指定者:

beforeLast 在接口中 ResultsetRows

get

public Row get(int atIndex)

从接口复制的说明: RowList

Optionally retrieve Row at index n. Only works on non dynamic row lists.

指定者:

get 在接口中 RowList

参数:

atIndex - row number

返回:

Row

getPosition

public int getPosition()

从接口复制的说明: RowList

Returns the current position.

指定者:

getPosition 在接口中 RowList

返回:

the current row number

hasNext

public boolean hasNext()

指定者:

hasNext 在接口中 Iterator<Row>

isAfterLast

public boolean isAfterLast()

从接口复制的说明: ResultsetRows

Returns true if we got the last element.

指定者:

isAfterLast 在接口中 ResultsetRows

返回:

true if after last row

isBeforeFirst

public boolean isBeforeFirst()

从接口复制的说明: ResultsetRows

Returns if iteration has not occured yet.

指定者:

isBeforeFirst 在接口中 ResultsetRows

返回:

true if before first row

isDynamic

public boolean isDynamic()

从接口复制的说明: ResultsetRows

Returns true if the result set is dynamic. This means that move back and move forward won't work because we do not hold on to the records.

指定者:

isDynamic 在接口中 ResultsetRows

返回:

true if this result set is streaming from the server

isEmpty

public boolean isEmpty()

从接口复制的说明: ResultsetRows

Has no records.

指定者:

isEmpty 在接口中 ResultsetRows

返回:

true if no records

isFirst

public boolean isFirst()

从接口复制的说明: ResultsetRows

Are we on the first row of the result set?

指定者:

isFirst 在接口中 ResultsetRows

返回:

true if on first row

isLast

public boolean isLast()

从接口复制的说明: ResultsetRows

Are we on the last row of the result set?

指定者:

isLast 在接口中 ResultsetRows

返回:

true if on last row

moveRowRelative

public void moveRowRelative(int rowsToMove)

从接口复制的说明: ResultsetRows

Moves the current position relative 'rows' from the current position.

指定者:

moveRowRelative 在接口中 ResultsetRows

参数:

rowsToMove - the relative number of rows to move

next

public Row next()

指定者:

next 在接口中 Iterator<Row>

remove

public void remove()

指定者:

remove 在接口中 Iterator<Row>

setCurrentRow

public void setCurrentRow(int newIndex)

从接口复制的说明: ResultsetRows

Moves the current position in the result set to the given row number.

指定者:

setCurrentRow 在接口中 ResultsetRows

参数:

newIndex - row to move to

size

public int size()

从接口复制的说明: RowList

Only works on non dynamic row lists.

指定者:

size 在接口中 RowList

返回:

the size of this row list

wasEmpty

public boolean wasEmpty()

从接口复制的说明: ResultsetRows

Did this result set have no rows?

指定者:

wasEmpty 在接口中 ResultsetRows

覆盖:

wasEmpty 在类中 AbstractResultsetRows

返回:

true if the result set did not have rows
