SwitchRuleHandler

public SwitchRuleHandler(IndentationCheck indentCheck,
 DetailAST expr,
 AbstractExpressionHandler parent)

Construct an instance of this handler with the given indentation check, abstract syntax tree, and parent handler.

Parameters:

indentCheck - the indentation check

expr - the abstract syntax tree

parent - the parent handler

Method Details

getIndentImpl

protected IndentLevel getIndentImpl()

Description copied from class: AbstractExpressionHandler

Compute the indentation amount for this handler.

Overrides:

getIndentImpl in class AbstractExpressionHandler

Returns:

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

checkIndentation

public void checkIndentation()

Description copied from class: AbstractExpressionHandler

Check the indentation of the expression we are handling.

Specified by:

checkIndentation in class AbstractExpressionHandler

isSameLineAsSwitch

private boolean isSameLineAsSwitch(DetailAST node)

Checks if the current SWITCH_RULE node is placed on the same line as the given SWITCH_LITERAL node.

Parameters:

node - the SWITCH_LITERAL node to compare with

Returns:

true if the current SWITCH_RULE node is on the same line as the given SWITCH_LITERAL node
