Method Details

getImplementation

public Expression getImplementation()

Description copied from class: Expression

Type checking may assign a more complex implementation to an innocuous-looking expression (like an identifier). Return that implementation, or the original expression itself if there is no special implementation.

This appears at present to be dead code, and is not called from within javac. Access to the implementation generally occurs within the same class, and thus uses the underlying field directly.

Overrides:

getImplementation in class Expression

equals

public boolean equals(Identifier id)

Check if the expression is equal to a value

Overrides:

equals in class Expression

assign

private Vset assign(Environment env,
 Context ctx,
 Vset vset)

Assign a value to this identifier. [It must already be "bound"]

get

private Vset get(Environment env,
 Context ctx,
 Vset vset)

Get the value of this identifier. [ It must already be "bound"]

bind

boolean bind(Environment env,
 Context ctx)

Bind to a field

checkValue

public Vset checkValue(Environment env,
 Context ctx,
 Vset vset,
 Hashtable<Object,Object> exp)

Check expression

Overrides:

checkValue in class Expression

checkLHS

public Vset checkLHS(Environment env,
 Context ctx,
 Vset vset,
 Hashtable<Object,Object> exp)

Check the expression if it appears on the LHS of an assignment

Overrides:

checkLHS in class Expression

checkAssignOp

public Vset checkAssignOp(Environment env,
 Context ctx,
 Vset vset,
 Hashtable<Object,Object> exp,
 Expression outside)

Check the expression if it appears on the LHS of an op= expression

Overrides:

checkAssignOp in class Expression

getAssigner

public FieldUpdater getAssigner(Environment env,
 Context ctx)

Return an accessor if one is needed for assignments to this expression.

Overrides:

getAssigner in class Expression

getUpdater

public FieldUpdater getUpdater(Environment env,
 Context ctx)

Return an updater if one is needed for assignments to this expression.

Overrides:

getUpdater in class Expression

checkAmbigName

public Vset checkAmbigName(Environment env,
 Context ctx,
 Vset vset,
 Hashtable<Object,Object> exp,
 UnaryExpression loc)

Check if the present name is part of a scoping prefix.

Overrides:

checkAmbigName in class Expression

toResolvedType

private ClassDefinition toResolvedType(Environment env,
 Context ctx,
 boolean pkgOK)

Convert an identifier to a known type, or null.

toType

Type toType(Environment env,
 Context ctx)

Convert an identifier to a type. If one is not known, use the current package as a qualifier.

Overrides:

toType in class Expression

isConstant

public boolean isConstant()

Check if constant: Will it inline away?

Overrides:

isConstant in class Expression

inline

public Expression inline(Environment env,
 Context ctx)

Inline

Overrides:

inline in class Expression

inlineValue

public Expression inlineValue(Environment env,
 Context ctx)

Overrides:

inlineValue in class Expression

inlineLHS

public Expression inlineLHS(Environment env,
 Context ctx)

Overrides:

inlineLHS in class Expression

copyInline

public Expression copyInline(Context ctx)

Description copied from class: Expression

Create a copy of the expression for method inlining

Overrides:

copyInline in class Expression

costInline

public int costInline(int thresh,
 Environment env,
 Context ctx)

Description copied from class: Expression

The cost of inlining this expression. This cost controls the inlining of methods, and does not determine the compile-time simplifications performed by 'inline' and friends.

Overrides:

costInline in class Expression

codeLValue

int codeLValue(Environment env,
 Context ctx,
 Assembler asm)

Code local vars (object fields have been inlined away)

Overrides:

codeLValue in class Expression

codeLoad

void codeLoad(Environment env,
 Context ctx,
 Assembler asm)

Overrides:

codeLoad in class Expression

codeStore

void codeStore(Environment env,
 Context ctx,
 Assembler asm)

Overrides:

codeStore in class Expression

codeValue

public void codeValue(Environment env,
 Context ctx,
 Assembler asm)

Overrides:

codeValue in class Expression

print

public void print(PrintStream out)

Print

Overrides:

print in class Expression
