Constructor Detail

AccessSymbol

public AccessSymbol(AccessExpression ae)

Constructs an object with the given access expression.

Parameters:

ae - the access expression which a symbol is created from.

AccessSymbol

public AccessSymbol(Symbol base,
            Symbol member)

Constructs a struct symbol with the given base and member symbol.

Parameters:

base - the base symbol.

member - the member symbol.

Method Detail

getTypeSpecifiers

public java.util.List getTypeSpecifiers()

Returns the list of type specifiers.

Specified by:

getTypeSpecifiers in interface Symbol

Returns:

the list of type specifiers.

getArraySpecifiers

public java.util.List getArraySpecifiers()

Returns the list of array specifiers.

Specified by:

getArraySpecifiers in interface Symbol

Returns:

the list of array specifiers.

getSymbolName

public java.lang.String getSymbolName()

Returns the name representation of the symbol.

Specified by:

getSymbolName in interface Symbol

Returns:

the name of the symbol.

equals

public boolean equals(java.lang.Object o)

Checks if the this symbol is equal to the the given object. The comparison comes down to symbol comparison which is hashcode comparison assuming the composed symbol such as AccessSymbol or DerefSymbol provides a correct equals method.

Specified by:

equals in class PseudoSymbol

Parameters:

o - the object to be compared with.

Returns:

true if they are equal, false otherwise.

hashCode

public int hashCode()

Returns the hash code of the current struct symbol.

Specified by:

hashCode in class PseudoSymbol

Returns:

the integer hash code for this struct symbol.

getBaseSymbol

public Symbol getBaseSymbol()

Returns the base symbol.

Returns:

the base symbol.

getMemberSymbol

public Symbol getMemberSymbol()

Returns the member symbol.

Returns:

the member symbol.

getIRSymbol

public Symbol getIRSymbol()

Returns the IR symbol from which the current symbol is derived. For this struct symbol the member symbol is returned since it is the one that describes the type information of this struct symbol.

Specified by:

getIRSymbol in class PseudoSymbol

Returns:

the symbol object that exist in the IR.
