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

getCompareType

public Type getCompareType()

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.

opEquals

public boolean opEquals(Operator o)

Overrides:

opEquals in class Operator

                    throws java.io.IOException

Specified by:

dumpExpression in class Operator

Throws:
