Method Details

appendSource

protected void appendSource(StringBuilder appendTo)

Implementers extend this to append their source to the given string builder. Done via string builder to encourage a more efficient implementation than is possible with concatenating multiple toString calls that typically contruct a string builder anyway.

keywordArgumentsOffset

public int keywordArgumentsOffset()

hasKeywordArguments

public boolean hasKeywordArguments()

indexOfArgNamed

public int indexOfArgNamed(String toFind)

Returns:

argIndex of argument with name toFind, or -1 if not found

accept

public <T,
R> R accept(ExpressionVisitor<T,R> visitor,
 T data)

getPositionalArguments

public List<FunctionCall.Argument> getPositionalArguments()

Builds a list of all the arguments that were given before the first keyword argument appears

Note that the parser is currently allowing (I think) positional elements to occur after keywords, which will break this code. We should probably stop this as I'm 99% sure we never want positional args to be interleaved with keyword args

equals

public boolean equals(Object o)

canEqual

protected boolean canEqual(Object other)

hashCode

public int hashCode()

getIdentifier

public Token getIdentifier()

getArguments

public List<FunctionCall.Argument> getArguments()

getBoundary

public Optional<Pair<Token,Token>> getBoundary()

Returns:

a pair of tokens that represent the start and end of this expression, to be used when giving users information about where errors have occurred. If the expression has been rebuilt then the boundary may be empty or it may be from the original expression. Intended for use in problems to trace errors back to their source.

toString

public final String toString()

Overrides:

toString in class Object

Returns:

the source, surrounded by the class name to make it easier to discern from a plane string among other debug output

toSource

public final String toSource()

Specified by:

toSource in interface Expression

Returns:

a normalized version of the AST that can be parsed to be exactly the same AST as this
