getIndentImpl

protected IndentLevel getIndentImpl()

Description copied from class: AbstractExpressionHandler

Compute the indentation amount for this handler.

Overrides:

getIndentImpl in class AbstractExpressionHandler

the expected indentation amount

checkCase

private void checkCase()

Check the indentation of the case statement.

getSuggestedChildIndent

public IndentLevel getSuggestedChildIndent(AbstractExpressionHandler child)

Description copied from class: AbstractExpressionHandler

Indentation level suggested for a child element. Children don't have to respect this, but most do.

Overrides:

getSuggestedChildIndent in class AbstractExpressionHandler

Parameters:

child - child AST (so suggestion level can differ based on child type)

Returns:

suggested indentation for child

Description copied from class: AbstractExpressionHandler

Check the indentation of the expression we are handling.

Specified by:

checkIndentation in class AbstractExpressionHandler
