Detailed Description

Defines the operators that are used when compiling expressions and algorithms.

This class allows to to create two 'operating set singletons' one for expressions and another for algorithms.

Constructor & Destructor Documentation

org.quark.jasmine.OperatorSet.OperatorSet ( )

private

Private constructor will create the expression set

org.quark.jasmine.OperatorSet.OperatorSet ( OperatorSet  set )

private

Private constructor will create the an operator set from another set. Extra operators can then be added.

Member Function Documentation

void org.quark.jasmine.OperatorSet.addAlgorithmOperators ( )

private

Add the extra operators needed for parsing algorithms.

void org.quark.jasmine.OperatorSet.addExp ( Exp  exp )

private

Add an expression to this set.

Parameters

exp

void org.quark.jasmine.OperatorSet.addOperators ( )

private

Add the operators needed for parsing expressions.

boolean org.quark.jasmine.OperatorSet.expExists ( String  symbol )

package

See if an operator exists based on its symbol

Exp org.quark.jasmine.OperatorSet.getExp ( String  symbol )

package

Create and return an Exp object based on its symbol. If the symbol can't be found it returns null

static OperatorSet org.quark.jasmine.OperatorSet.getOperatorSet ( int  type )

static

The parameter type determines which operator set to return. The actual operator set is created on first use.

Parameters

type	EXPRESSION or ALGORITHM

Returns

the appropriate operator set.

Pattern org.quark.jasmine.OperatorSet.getPattern ( )

package

Get the pattern for this set for the parser.

Returns

String org.quark.jasmine.OperatorSet.getRegex ( )

package

Get the operator set regular expression

Returns

void org.quark.jasmine.OperatorSet.makeRegex ( )

private

Once all the operators have been added this will create all the regular expressions for each operator and the whole set.

String org.quark.jasmine.OperatorSet.regexFromExpressions ( )

private

Calculates the regex for all expression symbols to be used when parsing

String org.quark.jasmine.OperatorSet.regexFromSymbol ( String  symbol )

private

Create a regular expression from a symbol. Basically prefixes reserved characters with a backslash.
