ApplyBuilder

protected ApplyBuilder()

ApplyBuilder

protected ApplyBuilder(SyntaxScheme scheme)
                throws ParsingException,
                       UnknownIdentifierException,
                       FunctionTypeException

Creates an ApplyBuilder instance from a SyntaxScheme.

Parameters:

scheme - SyntaxScheme to be parsed

Throws:

ParsingException

UnknownIdentifierException

FunctionTypeException

Method Detail

parse

protected void parse(SyntaxScheme scheme)
              throws ParsingException,
                     UnknownIdentifierException,
                     FunctionTypeException

Parsed an ApplyBuilder instance from a SyntaxScheme. It recognises the following new functions:

sub

res

act

env

and creates an one-and-only bag of the corresponding type, and fills it with the related argument value from the syntax scheme.

Parameters:

scheme - SyntaxScheme to be parsed

Throws:

ParsingException

UnknownIdentifierException

FunctionTypeException

getInstance

public Evaluatable getInstance()

Creates a a new Apply instance.

Specified by:

getInstance in class EvaluatableBuilder

EvaluatableBuilder.getInstance()

setBagFunction

public void setBagFunction(String expression)
                    throws UnknownIdentifierException,
                           FunctionTypeException

Sets the higher-order bag function to use. Parses the function from an syntax scheme expression.

Parameters:

expression - The syntax scheme of the bagFunction to set.

Throws:

FunctionTypeException

UnknownIdentifierException

setBagFunction

public void setBagFunction(Function bagFunction)

Sets the higher-order bag function to use.

Parameters:

bagFunction - The bagFunction to set.

setFunction

public void setFunction(String expression)
                 throws UnknownIdentifierException,
                        FunctionTypeException

Sets the Function to use in evaluating the elements in the apply. Parses the function from an syntax scheme expression.

Parameters:

expression - The syntax scheme of the function to set.

Throws:

FunctionTypeException

UnknownIdentifierException

setFunction

public void setFunction(Function function)

Sets the Function to use in evaluating the elements in the apply.

Parameters:

function - The function to set.

remove

public boolean remove(Evaluatable eval)

Removes an Evaluatable to the evaluation list.

Overrides:

remove in class EvaluatableBuilder

Parameters:

eval - The evaluatable to remove.

Returns:

true if the evaluatable has been removed succesfully.
