Field Detail

number

int number

The number of the variable

readcount

int readcount

Some statistics

writecount

int writecount

scopeNumber

int scopeNumber

An indication of which block the variable comes from. Helps identify uplevel references.

originalOfCopy

LocalMember originalOfCopy

Used by copyInline to record the original of this copy.

prev

LocalMember prev

The previous local variable, this list is used to build a nested context of local variables.

Constructor Detail

LocalMember

public LocalMember(long where,
                   ClassDefinition clazz,
                   int modifiers,
                   Type type,
                   Identifier name)

Constructor

LocalMember

public LocalMember(ClassDefinition innerClass)

Constructor for a block-inner class.

LocalMember

LocalMember(MemberDefinition field)

Constructor for a proxy to an instance or class variable.

Method Detail

getScopeNumber

public int getScopeNumber()

Return current nesting level, i.e., the value of 'scopeNumber'. Made public for the benefit of 'ClassDefinition.resolveName'.

getMember

final MemberDefinition getMember()

Is this a proxy for the given field?

isLocal

public boolean isLocal()

Special checks

Overrides:

isLocal in class MemberDefinition

copyInline

public LocalMember copyInline(Context ctx)

Make a copy of this field, which is an argument to a method or constructor. Arrange so that when occurrences of the field are encountered in an immediately following copyInline() operation, the expression nodes will replace the original argument by the fresh copy.

getCurrentInlineCopy

public LocalMember getCurrentInlineCopy(Context ctx)

Returns the previous result of copyInline(ctx). Must be called in the course of an Expression.copyInline() operation that immediately follows the LocalMember.copyInline(). Return "this" if there is no such copy.

copyArguments

public static LocalMember[] copyArguments(Context ctx,
                                          MemberDefinition field)

May inline copies of all the arguments of the given method.

doneWithArguments

public static void doneWithArguments(Context ctx,
                                     LocalMember[] res)

Call this when finished with the result of a copyArguments() call.

isInlineable

public boolean isInlineable(Environment env,
                            boolean fromFinal)

Is this local variable's value stable and simple enough to be directly substituted for occurrences of the variable itself? (This decision is made by VarDeclarationStatement.inline().)

Overrides:

isInlineable in class MemberDefinition

isUsed

public boolean isUsed()

Check if used

getAccessVar

LocalMember getAccessVar()

setAccessVar

void setAccessVar(LocalMember f)

getAccessVarMember

MemberDefinition getAccessVarMember()

setAccessVarMember

void setAccessVarMember(MemberDefinition f)

getValue

public Node getValue(Environment env)

Return value

Overrides:

getValue in class MemberDefinition

getNumber

public int getNumber(Context ctx)

Value number for vsets, or -1 if none.
