All Implemented Interfaces:

java.lang.CharSequence, Name

Direct Known Subclasses:

SharedNameTable.NameImpl, UnsharedNameTable.NameImpl

public abstract class Name
extends java.lang.Object
implements Name

An abstraction for internal compiler strings. They are stored in Utf8 format. Names are stored in a Name.Table, and are unique within that table.

This is NOT part of any API supported by Sun Microsystems. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

Method Detail

contentEquals

public boolean contentEquals(java.lang.CharSequence cs)

Description copied from interface: Name

Compares this name to the specified CharSequence. The result is true if and only if this name represents the same sequence of char values as the specified sequence.

Specified by:

contentEquals in interface Name

Parameters:

cs - The sequence to compare this name against

Returns:

true if this name represents the same sequence of char values as the specified sequence, false otherwise
