Field Detail

dt

public final org.relaxng.datatype.Datatype dt

Datatype object that is used to test the equality.

value

public final Object value

This expression matches this value only.

name

public final StringPair name

name of this datatype. The value of this field is not considered as significant. When two TypedStringExps share the same Datatype object, then they are unified even if they have different names.

Constructor Detail

ValueExp

protected ValueExp(org.relaxng.datatype.Datatype dt,
                   StringPair typeName,
                   Object value)

Method Detail

getType

public org.relaxng.datatype.Datatype getType()

Specified by:

getType in interface DataOrValueExp

getName

public StringPair getName()

Specified by:

getName in interface DataOrValueExp

calcHashCode

protected final int calcHashCode()

Description copied from class: Expression

Computes the hashCode again.

This method and the parameter to the constructor has to be the same. This method is used when the object is being read from the stream.

Specified by:

calcHashCode in class Expression

equals

public boolean equals(Object o)

Specified by:

equals in class Expression

visit

public Object visit(ExpressionVisitor visitor)

Specified by:

visit in class Expression

visit

public Expression visit(ExpressionVisitorExpression visitor)

Specified by:

visit in class Expression

visit

public boolean visit(ExpressionVisitorBoolean visitor)

Specified by:

visit in class Expression

visit

public void visit(ExpressionVisitorVoid visitor)

Specified by:

visit in class Expression

calcEpsilonReducibility

protected boolean calcEpsilonReducibility()

Description copied from class: Expression

computes epsilon reducibility

Specified by:

calcEpsilonReducibility in class Expression
