Constructor Detail

Parenthesis

Parenthesis()

Constructor for serialization.

Parenthesis

public Parenthesis(ConstraintSyntaxTree expr)

Creates a new parenthesis node.

Parameters:

expr - the nested expression

Method Detail

getExpr

public ConstraintSyntaxTree getExpr()

Returns the nested expression.

Returns:

the nested expression

inferDatatype

public IDatatype inferDatatype()
                        throws CSTSemanticException

Description copied from class: ConstraintSyntaxTree

Infers the datatype of the subtree represented by this object.

Specified by:

inferDatatype in class ConstraintSyntaxTree

Returns:

the data type

Throws:

CSTSemanticException - Will be thrown if parameters of (sub-) trees do not fit together.

accept

public void accept(IConstraintTreeVisitor visitor)

Description copied from class: ConstraintSyntaxTree

Visiting method for the visitor.
This method is used for saving this model element.

Specified by:

accept in class ConstraintSyntaxTree

Parameters:

visitor - The visitor, which should save this model element.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

isSemanticallyEqual

public boolean isSemanticallyEqual(ConstraintSyntaxTree otherTree)

Description copied from class: ConstraintSyntaxTree

Checks whether this ConstraintSyntaxTree is semantically equal to another ConstraintSyntaxTree. Attention:This method is not fully supported by all operations and sub classes.

Overrides:

isSemanticallyEqual in class ConstraintSyntaxTree

Parameters:

otherTree - Another cst to check whether it is semantically equal to this cst.

Returns:

true if both trees are semantically equal, false otherwise.
