Constructor Detail

AccessPathThis

public AccessPathThis(polyglot.types.ClassType ct,
                      polyglot.util.Position pos)
Parameters:
ct - may be null.
Method Detail

isCanonical

public boolean isCanonical()
Specified by:
isCanonical in class AccessPath

isNeverNull

public boolean isNeverNull()
Specified by:
isNeverNull in class AccessPath

subst

public AccessPath subst(AccessPathRoot r,
                        AccessPath e)
Description copied from class: AccessPath
Return the result of substituting the root r with the access path e. For example, given a field access path "this.f", substituting the access path root "this" for the access path "o.g" will result in the access path "o.g.f". This method is used to instantiate procedures for calls, and labels of fields.

Specified by:
subst in class AccessPath

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object

exprString

public java.lang.String exprString()
Overrides:
exprString in class AccessPath

equals

public boolean equals(java.lang.Object o)
Specified by:
equals in class AccessPath

hashCode

public int hashCode()
Specified by:
hashCode in class AccessPath

type

public polyglot.types.Type type()
Description copied from class: AccessPath
The type of the access path (when the access path is regarded as an expression).

Specified by:

labelcheck

public PathMap labelcheck(JifContext A,
                          LabelChecker lc)
Overrides:

verify

public void verify(JifContext A)
            throws polyglot.types.SemanticException
Description copied from class: AccessPath
Go through the path, check that all the type information is set correctly, and check that every field access is to a final field, and any local used is final

Overrides:
verify in class AccessPath
Throws:
polyglot.types.SemanticException
