public DefaultLineWrapper()

The constructor.

Method Detail

getHyphenatorBuilder

protected HyphenatorBuilder getHyphenatorBuilder()

Returns:

the hyphenatorBuilder

setHyphenatorBuilder

@Inject
public void setHyphenatorBuilder(HyphenatorBuilder hyphenatorBuilder)

Parameters:

hyphenatorBuilder - is the hyphenatorBuilder to set

doInitialize

protected void doInitialize()

Description copied from class: AbstractComponent

This method performs the actual initialization. It is called when AbstractComponent.initialize() is invoked for the first time.
ATTENTION:
When you override this method from a sub-class you need to do a super.AbstractComponent.doInitialize().

Overrides:

doInitialize in class AbstractLoggableComponent

autoAdjustWidthOfColumns

protected void autoAdjustWidthOfColumns(DefaultLineWrapper.ColumnState[] columnStates,
                                        TextTableInfo tableInfo)

This method calculates the width of the columns to auto-adjust.

Parameters:

columnStates - are the DefaultLineWrapper.ColumnStates.

tableInfo - is the TextTableInfo containing the available width.

wrap

public int wrap(Appendable appendable,
                TextTableInfo tableInfo,
                TextColumn... columns)

Description copied from interface: LineWrapper

This method is like LineWrapper.wrap(Appendable, TextTableInfo, String, TextColumnInfo, String, TextColumnInfo, String, TextColumnInfo) for any number of columns.

Parameters:

appendable - is the target where to append to.

tableInfo - is the TextTableInfo for the general layout.

columns - are the columns to append.

Returns:

the number of lines that have been appended excluding the first line. In other words the number of line separators that have been appended.

verifyWithOfColumns

private boolean verifyWithOfColumns(DefaultLineWrapper.ColumnState[] columnStates,
                                    TextTableInfo tableInfo)

This method verifies that the width of the columns are sane.

Parameters:

columnStates - are the DefaultLineWrapper.ColumnStates.

tableInfo - is the TextTableInfo.

Returns:

true if the width is sane, false otherwise.

isIn

private static boolean isIn(char c,
                            char[] chars)

This method determines if the given character c is contained in chars.

Parameters:

c - is the character to check.

chars - is the array with the matching characters.

Returns:

true if c is contained in chars, false otherwise.

appendCellBuffer

protected void appendCellBuffer(DefaultLineWrapper.ColumnState state,
                                DefaultLineWrapper.CellBuffer buffer)

This method fills the DefaultLineWrapper.CellBuffer with the payload for the current cell.

Parameters:

state - is the DefaultLineWrapper.ColumnState.

buffer - is the DefaultLineWrapper.CellBuffer.

append

protected void append(Appendable appendable,
                      DefaultLineWrapper.ColumnState state,
                      DefaultLineWrapper.CellBuffer cellBuffer)
               throws IOException

This method appends the text of a single cell (line of a single column).

Parameters:

appendable - is the Appendable where to append the text to.

state - the DefaultLineWrapper.ColumnState of the current column where to fill a single cell.

cellBuffer - is the DefaultLineWrapper.CellBuffer for the payload of the current cell.

Throws:

IOException - if caused by the Appendable.

appendWithAlignment

protected void appendWithAlignment(Appendable appendable,
                                   DefaultLineWrapper.ColumnState state,
                                   boolean doIndentThisLine,
                                   DefaultLineWrapper.CellBuffer cellBuffer)
                            throws IOException

This method actually appends the text for a single line of a single column according to alignment.

Parameters:

appendable - is where to append to.

state - is the current DefaultLineWrapper.ColumnState.

doIndentThisLine - - true if the current cell should be indented, false otherwise.

cellBuffer - is the text to align and append.

Throws:

IOException - if throw by the Appendable.

fill

protected void fill(Appendable appendable,
                    char filler,
                    int count)
             throws IOException

This method fills the Appendable with the given count of filler characters.

Parameters:

appendable - is the Appendable to fill.

filler - is the fill-character.

count - is the number of fill-characters (filler) to add.

Throws:

IOException - if caused by the Appendable.
