Constructor Details

JAssignStmt

public JAssignStmt(@Nonnull
 LValue variable,
 @Nonnull
 Value rValue,
 @Nonnull
 StmtPositionInfo positionInfo)

Instantiates a new JAssignStmt.

Parameters:

variable - the variable on the left side of the assign statement.

rValue - the value on the right side of the assign statement.

Method Details

containsInvokeExpr

public boolean containsInvokeExpr()

Description copied from interface: InvokableStmt

Checks if the invokable statement contains a invoke expression that defines the invoke.

Specified by:

containsInvokeExpr in interface InvokableStmt

Returns:

true if the statement contains an invoke expression, false if not

invokesStaticInitializer

public boolean invokesStaticInitializer()

Description copied from interface: InvokableStmt

Checks if the invokable statement can potentially invoke a static initializer To cause a static initializer call, the statement contains a static method call, a new expression, or a static field reference.

Specified by:

invokesStaticInitializer in interface InvokableStmt

Returns:

true if the statement can cause a static initializer call, and false if not.

getInvokeExpr

public Optional<AbstractInvokeExpr> getInvokeExpr()

Description copied from interface: InvokableStmt

Returns the possible invoke expression in the invokable statement

Specified by:

getInvokeExpr in interface InvokableStmt

Returns:

The optional contains the invoke expression of the invokable statement or is empty if there is no invoke expression.

containsArrayRef

public boolean containsArrayRef()

Specified by:

containsArrayRef in interface Stmt

Overrides:

containsArrayRef in class AbstractStmt

getArrayRef

public JArrayRef getArrayRef()

Description copied from class: AbstractStmt

This method must only be used for Stmts which contain an ArrayRef - possible with JAssignStmts. check via containsArrayRef().

Specified by:

getArrayRef in interface Stmt

Overrides:

getArrayRef in class AbstractStmt

containsFieldRef

public boolean containsFieldRef()

Specified by:

containsFieldRef in interface Stmt

Overrides:

containsFieldRef in class AbstractStmt

getFieldRef

public JFieldRef getFieldRef()

Description copied from class: AbstractStmt

This method must only be used for Stmts which contain an FieldRef - possible with JAssignStmts. check via containsFieldRef().

Specified by:

getFieldRef in interface Stmt

Overrides:

getFieldRef in class AbstractStmt

toString

public String toString()

Overrides:

toString in class Object

toString

public void toString(@Nonnull
 StmtPrinter up)

Specified by:

toString in interface Stmt

accept

public <V extends StmtVisitor> V accept(@Nonnull
 V v)

Description copied from interface: Acceptor

Called when this object is visited.

Specified by:

accept in interface Acceptor<StmtVisitor>

equivTo

public boolean equivTo(Object o,
 @Nonnull
 JimpleComparator comparator)

Description copied from interface: EquivTo

Returns true if this object is equivalent to o according to the given comparator.

Specified by:

equivTo in interface EquivTo

equivHashCode

public int equivHashCode()

Description copied from interface: EquivTo

Returns a (not necessarily fixed) hash code for this object. This hash code coincides with equivTo; it is undefined in the presence of mutable objects. The contract is defined in JimpleComparator.

Specified by:

equivHashCode in interface EquivTo

getLeftOp

@Nonnull
public LValue getLeftOp()

Specified by:

getLeftOp in class AbstractDefinitionStmt

getRightOp

@Nonnull
public Value getRightOp()

Specified by:

getRightOp in class AbstractDefinitionStmt

fallsThrough

public boolean fallsThrough()

Description copied from interface: Stmt

Returns true if execution after this statement may continue at the following statement. (e.g. GotoStmt will return false and e.g. IfStmt will return true).

Specified by:

fallsThrough in interface FallsThroughStmt

Specified by:

fallsThrough in interface Stmt

Overrides:

fallsThrough in class AbstractDefinitionStmt

branches

public boolean branches()

Description copied from interface: Stmt

Returns true if execution after this statement does not necessarily continue at the following statement. The BranchingStmt's GotoStmt, JSwitchStmt and IfStmt will return true.

Specified by:

branches in interface Stmt

Overrides:

branches in class AbstractDefinitionStmt

withNewDef

@Nonnull
public JAssignStmt withNewDef(@Nonnull
 Local newLocal)

Specified by:

withNewDef in class AbstractDefinitionStmt

withVariable

@Nonnull
public JAssignStmt withVariable(@Nonnull
 LValue variable)

withRValue

@Nonnull
public JAssignStmt withRValue(@Nonnull
 Value rValue)

withPositionInfo

@Nonnull
public JAssignStmt withPositionInfo(@Nonnull
 StmtPositionInfo positionInfo)
