ast - the abstract syntax tree

parent - the parent handler

Method Details

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 BlockParentHandler

Parameters:

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

Returns:

suggested indentation for child

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

isIfAfterElse

private boolean isIfAfterElse()

Determines if this 'if' statement is part of an 'else' clause and on the same line.

Returns:

true if this 'if' is part of an 'else', false otherwise

checkTopLevelToken

protected void checkTopLevelToken()

Description copied from class: BlockParentHandler

Check the indent of the top level token.

Overrides:

private void checkCondExpr()

Check the indentation of the conditional expression.

checkIndentation

public void checkIndentation()

Description copied from class: AbstractExpressionHandler

Check the indentation of the expression we are handling.

Overrides:
