Constructor Detail

IIncOperator

public IIncOperator(LocalStoreOperator localStore,
                    int value,
                    int operator)

Method Detail

getLValue

public LValueExpression getLValue()

Description copied from interface: CombineableOperator

Returns the LValue.

Specified by:

getLValue in interface CombineableOperator

getValue

public int getValue()

getPriority

public int getPriority()

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
• 650 *,/, %
• 610 +,-
• 600 <<, >>, >>>
• 550 >, <, >=, <=, instanceof
• 500 ==, !=
• 450 &
• 420 ^
• 410 |
• 350 &&
• 310 ||
• 200 ?:
• 100 =, +=, -=, etc.

Specified by:

getPriority in class Expression

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 out of this store instruction.

Specified by:

makeNonVoid in interface CombineableOperator

lvalueMatches

public boolean lvalueMatches(Operator loadop)

Description copied from interface: CombineableOperator

Checks if the loadOp is combinable with the lvalue.

Specified by:

lvalueMatches in interface CombineableOperator

simplify

public Expression simplify()

Overrides:

simplify in class Operator

dumpExpression

public void dumpExpression(TabbedPrintWriter writer)
                    throws java.io.IOException

Specified by:

dumpExpression in class Operator

Throws:

java.io.IOException
