                  DetailAST ast,
                  AbstractExpressionHandler parent)

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

Parameters:

indentCheck - the indentation check

ast - the abstract syntax tree

parent - the parent handler

Method Detail

checkIndentation

public void checkIndentation()

Description copied from class: AbstractExpressionHandler

Check the indentation of the expression we are handling.

Specified by:

checkIndentation in class AbstractExpressionHandler

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

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

getLineWrappingIndent

private int getLineWrappingIndent()

A shortcut for IndentationCheck property.

Returns:

value of lineWrappingIndentation property of IndentationCheck

shouldIncreaseIndent

protected boolean shouldIncreaseIndent()

Description copied from class: AbstractExpressionHandler

Checks that indentation should be increased after first line in checkLinesIndent().

Overrides:

shouldIncreaseIndent in class AbstractExpressionHandler

Returns:

true if indentation should be increased after first line in checkLinesIndent() false otherwise

doesChainedMethodNeedsLineWrapping

private boolean doesChainedMethodNeedsLineWrapping()

The function checks if the new keyword is a child of chained method calls, it checks if the new is directly followed by equal operator or return operator.

Returns:
