public RegularExpressionParser.Literal(java.lang.String lit)

It constructs a literal.

Parameters:

lit - string representation of the literal.

Method Detail

getType

public int getType()

Description copied from class: RegularExpressionParser.Expression

If the given string contains the words that this Expression object requires, this method returns an array of ints. In most cases, the array contains the offsets of the words in the string that are required by this combination. However, if the array is empty, then all the words in the string satisfy the Expression. If the given string does not contain the words that this Expression object requires, then this method returns null.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object c)

Overrides:

equals in class java.lang.Object

isSimple

public boolean isSimple()

Description copied from class: RegularExpressionParser.Expression

It specifies if the expression is simple.

Overrides:

isSimple in class RegularExpressionParser.Expression

Returns:

true if expression is a literal or disjunction of literals.

parseToFSM

public FSM parseToFSM()

Description copied from class: RegularExpressionParser.Expression

It creates Finite State Machine from the expression.

Specified by:

parseToFSM in class RegularExpressionParser.Expression

Returns:

Finite State Machine corresponding
