Method Detail

isCanonical

public boolean isCanonical()

Specified by:

isCanonical 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

name

isNeverNull

public boolean isNeverNull()

Specified by:

isNeverNull in class AccessPath

setIsNeverNull

public void setIsNeverNull()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

exprString

public java.lang.String exprString()

Overrides:

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:

type in class AccessPath

labelcheck

public PathMap labelcheck(JifContext A,
                          LabelChecker lc)

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
