Description copied from class: Expression

Get priority of the operator. Currently this priorities are known:

• 1000 constant
• 950 new, .(field access), []
• 900 new[]
• 800 ++,-- (post)
• 700 ++,--(pre), +,-(unary), ~, !, cast

• 500 ==, !=
• 450 &
• 420 ^
• 410 |
• 350 &&
• 310 ||
• 200 ?:
• 100 =, +=, -=, etc.

Specified by:

getPriority in class Expression

checkAnonymousClasses

public void checkAnonymousClasses()

updateSubTypes

public void updateSubTypes()

Description copied from class: Expression

Tells an expression that an outer expression has changed our type and that the inner types should be recalculated.

Specified by:

updateSubTypes in class Expression

updateType

public void updateType()

Description copied from class: Expression

Tells an expression that an inner expression may have changed and that the type should be recalculated. This may call setType of the caller again.

Specified by:

updateType in class Expression

makeNonVoid

public void makeNonVoid()

Makes a non void expression, in case this is a constructor.

isConstructor

public boolean isConstructor()

getClassInfo

public ClassInfo getClassInfo()

isThis

public boolean isThis()

Checks, whether this is a call of a method from this class.

getClassAnalyzer

public ClassAnalyzer getClassAnalyzer()

Tries to locate the class analyzer for the callee class. This is mainly useful for inner and anonymous classes.

Returns:

The class analyzer, if the callee class is declared inside the same base class as the caller class, null otherwise.

isOuter

public boolean isOuter()

Checks, whether this is a call of a method from this class or an outer instance.

getMethodAnalyzer

public MethodAnalyzer getMethodAnalyzer()

Tries to locate the method analyzer for the callee. This is mainly useful for inner and anonymous classes.

Returns:

The method analyzer, if the callee is declared inside the same base class as the caller class, null otherwise.

isSuperOrThis

public boolean isSuperOrThis()

Checks, whether this is a call of a method from the super class.

isConstant

public boolean isConstant()

Overrides:

isConstant in class Operator

matches

public boolean matches(Operator loadop)

Checks if the value of the operator can be changed by this expression.

Specified by:

matches in interface MatchableOperator

isGetClass

public boolean isGetClass()

Checks if the method is the magic class$ method.

Returns:

true if this is the magic class$ method, false otherwise.

deobfuscateString
