Method Detail

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

isStatic

public boolean isStatic()

getClassInfo

public ClassInfo getClassInfo()

getField

public FieldAnalyzer getField()

Returns the field analyzer for the field, if the field is declared in the same class or some outer class as the method containing this instruction. Otherwise it returns null.

Returns:

see above.

getFieldName

public java.lang.String getFieldName()

getFieldType

public Type getFieldType()

getFieldInfo

public FieldInfo getFieldInfo()

needsCast

public boolean needsCast(Type type)

fillDeclarables

public void fillDeclarables(java.util.Collection used)

We add the named method scoped classes to the declarables.

Overrides:

fillDeclarables in class Operator

dumpExpression

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

Specified by:

dumpExpression in class Operator

Throws:

java.io.IOException
