Constructor Detail

SoftWrapImpl

public SoftWrapImpl(TextChangeImpl change,
                    int indentInColumns,
                    int indentInPixels)

Method Detail

getStart

public int getStart()

Specified by:

getStart in interface TextChange

Returns:

start index (inclusive) of text range affected by the change encapsulated at the current object

getEnd

public int getEnd()

Specified by:

getEnd in interface TextChange

Returns:

end index (exclusive) of text range affected by the change encapsulated at the current object

getText

public java.lang.CharSequence getText()

Description copied from interface: TextChange

Allows to retrieve text that is directly affected by the change encapsulated by the current object.

Specified by:

getText in interface TextChange

Returns:

text related to the change encapsulated by the current object

getChars

public char [] getChars()

Description copied from interface: TextChange

Allows to get change text as a char array. Note that it's not guaranteed that change text directly maps to the returned char array, i.e. change to array content is not obeyed to be reflected in TextChange.getText() result.

Generally speaking, this method is introduced just as a step toward existing high-performance services that work in terms of char arrays. Resulting array is instantiated on-demand via CharArrayUtil.fromSequence(CharSequence), hence, it doesn't hit memory if, for example, CharSequenceBackedByArray is used as initial change text.

Specified by:

getChars in interface TextChange

Returns:

stored change text as a char array

getIndentInColumns

public int getIndentInColumns()

Specified by:

getIndentInColumns in interface SoftWrap

Returns:

number of columns between current soft wrap end and first column on a visual line

getIndentInPixels

public int getIndentInPixels()

Specified by:

getIndentInPixels in interface SoftWrap

Returns:

number of pixels between current soft wrap end and first column on a visual line

getChange

public TextChangeImpl getChange()

advance

public void advance(int diff)

hashCode

public int hashCode()

Overrides:

equals

public boolean equals(java.lang.Object o)

Overrides:

toString
