Method Summary

Modifier and Type	Method and Description
protected void	beginStatement(int index, StringBuilder newJs, ArrayList<Integer> starts) Record start of statement, and optionally inject new open block.
protected void	beginStatements(StringBuilder newJs, ArrayList<Integer> starts, ArrayList<Integer> ends) Called if any operations need to be performed before all statements have been processed.
protected void	endStatement(int index, StringBuilder newJs, ArrayList<Integer> ends) Record end of statement, and optionally inject close block, if block is full.
protected void	endStatements(StringBuilder newJs, ArrayList<Integer> starts, ArrayList<Integer> ends) Used to close a trailing block which never filled.
void	exec() Do not perform clustering, only fix up IE7 block issue.
Set<Integer>	getStatementsAddedBlockClose()
Set<Integer>	getStatementsAddedBlockOpen()
protected void	updateSourceInfoMap() Fixes the index ranges of individual expressions in the generated JS after chunking statements into blocks that satisfy the IE block size problem.

Method Detail

exec

public void exec()

Do not perform clustering, only fix up IE7 block issue.

Specified by:

exec in class JsAbstractTextTransformer

getStatementsAddedBlockClose

public Set<Integer> getStatementsAddedBlockClose()

getStatementsAddedBlockOpen

public Set<Integer> getStatementsAddedBlockOpen()

beginStatement

protected void beginStatement(int index,
                              StringBuilder newJs,
                              ArrayList<Integer> starts)

Record start of statement, and optionally inject new open block.

Overrides:

beginStatement in class JsAbstractTextTransformer

beginStatements

protected void beginStatements(StringBuilder newJs,
                               ArrayList<Integer> starts,
                               ArrayList<Integer> ends)

Description copied from class: JsAbstractTextTransformer

Called if any operations need to be performed before all statements have been processed.

Overrides:

beginStatements in class JsAbstractTextTransformer

endStatement

protected void endStatement(int index,
                            StringBuilder newJs,
                            ArrayList<Integer> ends)

Record end of statement, and optionally inject close block, if block is full.

Overrides:

endStatement in class JsAbstractTextTransformer

endStatements

protected void endStatements(StringBuilder newJs,
                             ArrayList<Integer> starts,
                             ArrayList<Integer> ends)

Used to close a trailing block which never filled.

Overrides:

endStatements in class JsAbstractTextTransformer

updateSourceInfoMap

protected void updateSourceInfoMap()

Fixes the index ranges of individual expressions in the generated JS after chunking statements into blocks that satisfy the IE block size problem. Loops over each expression, determines whether the statement in which it falls has a brace inserted before/after, and shifts forward according to where it falls in the block.

Specified by:
