                        LocalInfo local)

Method Detail

isRead

public abstract boolean isRead()

isWrite

public abstract boolean isWrite()

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

fillInGenSet

public void fillInGenSet(java.util.Collection in,
                         java.util.Collection gen)

Overrides:

fillInGenSet in class Operator

fillDeclarables

public void fillDeclarables(java.util.Collection used)

Overrides:

getLocalInfo

public LocalInfo getLocalInfo()

setLocalInfo

public void setLocalInfo(LocalInfo newLocal)

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.
