Method Detail

toString

public java.lang.String toString()

Returns a string representation of the object.

Overrides:

toString in class java.lang.Object

compact

void compact(ConstPool cp)

Copies all constant pool items to a given new constant pool and replaces the original items with the new ones. This is used for garbage collecting the items of removed fields and methods.

Parameters:

cp - the destination

prune

void prune(ConstPool cp)

getConstPool

public ConstPool getConstPool()

Returns the constant pool table used by this field_info.

getName

public java.lang.String getName()

Returns the field name.

setName

public void setName(java.lang.String newName)

Sets the field name.

getAccessFlags

public int getAccessFlags()

Returns the access flags.

getConstantValue

public int getConstantValue()

Finds a ConstantValue attribute and returns the index into the constant_pool table.

Returns:

0 if a ConstantValue attribute is not found.

getAttributes

public java.util.List getAttributes()

Returns all the attributes. The returned List object is shared with this object. If you add a new attribute to the list, the attribute is also added to the field represented by this object. If you remove an attribute from the list, it is also removed from the field.
