Default constructor.

ComplexEntry

public ComplexEntry(int classIndex,
                    int nameAndTypeIndex)

Constructor.

Parameters:

classIndex - the constant pool index of the ClassEntry describing the owner of this entity

nameAndTypeIndex - the constant pool index of the NameAndTypeEntry describing this entity

Method Detail

getClassIndex

public int getClassIndex()

Return the constant pool index of the ClassEntry describing the owning class of this entity. Defaults to 0.

setClassIndex

public void setClassIndex(int classIndex)

Set the constant pool index of the ClassEntry describing the owning class of this entity.

getClassEntry

public ClassEntry getClassEntry()

setNameAndTypeIndex

public void setNameAndTypeIndex(int nameAndTypeIndex)

Set the constant pool index of the NameAndTypeEntry describing this entity.

getNameAndTypeEntry

public NameAndTypeEntry getNameAndTypeEntry()

Return the referenced NameAndTypeEntry. This method can only be run for entries that have been added to a constant pool.
