Method Detail

getOperatorCharacters

java.lang.String getOperatorCharacters()

The set of characters, which could form an operator

getIdentifier2OperatorMap

java.util.Map<java.lang.String,AbstractExprOperator> getIdentifier2OperatorMap()

Get the identifier to operator map

Returns:

the map which stores the Operators for a given head string like Times, Plus, Sin,...

getOperator2ListMap

java.util.Map<java.lang.String,java.util.ArrayList<AbstractExprOperator>> getOperator2ListMap()

Get the operator-string to possible operator-list map

Returns:

the map which stores the operator-list for a given operator string like *, +, ==...

get

AbstractExprOperator get(java.lang.String identifier)

Get the operator for a given identifier string like Times, Plus, Sin,...

Parameters:

identifier -

Returns:

getOperatorList

java.util.List<AbstractExprOperator> getOperatorList(java.lang.String operatorString)

Get the operator-list for a given operator-string

Returns:

the operator-list for a given operator string like *, +, ==...

isValidIdentifier

boolean isValidIdentifier(java.lang.String identifier)

Check if the identifier name is valid.

Parameters:

identifier - the currently parsed identifier

Returns:

false if the identifier is not valid (in this case the parser creates a SyntaxError exception); otherwise return true
